Razzhood Kids' AI Glasses Q&A

Razzhood is a high-quality pair of sports glasses for children and teenagers, with a camera: offline stills, offline recording, two-way privacy, a Bluetooth headset and AI apps, all in the one pair.

The frame is designed, made and finished the way premium sports eyewear is, and any professional optician can fit it with lenses.

Razzhood is a pair of AI glasses built on high-end sports-eyewear craft. There is one form, and it has the camera.

It uses a TR90 frame, titanium hinges and trim, and liquid-silicone air-cushion nose pads, and any optician can fit it with prescription lenses for myopia, hyperopia and astigmatism.

"Razz" was taken for its sound, 瑞兹; "hood" for its meaning, 帽. Together they make 瑞兹帽, the Chinese name for Razzhood.

The brand reads itself this way: every wizard has magic. But there are spells only the exceptionally gifted can say out loud.

The temples are brandless: only the black hole logo, with no Razzhood and no "瑞兹帽" printed on them. When someone asks a child what glasses those are, they can answer: "They are 瑞兹帽. I backed them very early on, which also made me one of the first donors to the Musk Institute."

It is built around offline stills, offline recording and two-way privacy; it also puts frame materials, craft, sizing and long-term wear for children and teenagers at the centre rather than at the margins.

Recordings stay on the glasses themselves, with no dependence on your phone's connection. No signal, aeroplane mode, phone left behind — you can still capture your own voice.

Because a software promise can be quietly rewritten in the next firmware update, and geometry cannot.

When you speak, your voice reaches the main mic 7 to 9 dB louder than the reference mic. When someone half a metre away speaks, the two mics are almost equidistant from them and the difference is under 1 dB. The threshold sits at 4–5 dB, and anything below it is never written.

No DSP, no beamforming, no voiceprint, no model, no added cost. And no way to switch it off — it is not a setting, it is where the holes are drilled.

No, and that is deliberate.

At the hardware level it records the wearer and no one else — a few people brainstorming, an interview, a lecture, this pair cannot do it, and a voice recorder is the right tool for that.

Online meetings are another matter. If you want your own half of the meeting kept separately, this fits exactly: what comes back is the part you said.

No screen, and no AR. Nothing is projected in front of your eyes.

What we build is the input layer: take what you say and what is in front of you cleanly, then hand it to the phone. What it turns into after that is a question for when you are back at a screen.

The glasses connect over Bluetooth to AI apps on a phone or a computer, such as Doubao, Qwen and voice-driven coding tools. Anything that needs a large model runs on the phone, on the computer or in the cloud.

The Razzhood companion app handles pairing and content management, and is planned for iPhone, iPad and Android phones and tablets; over Bluetooth the glasses also work with AI applications on computers running macOS or Windows. Exact OS versions, store regions and the feature list are whatever the launch notes say at release.

iOS, iPadOS and Android are planned; the glasses also pair with macOS and Windows computers as a Bluetooth audio device. Features may open up on different platforms in stages, and the app store listing and the compatibility list are the final word.

The hardware itself carries no compulsory monthly fee. When you connect a third-party AI app, that app's own terms decide whether it charges you.

The images on this page show the current design direction. Colours, structural details, electronics and accessories on the production version are whatever the shipping product and the purchase page say.

The glasses are built around offline stills and do not do continuous long-form video. That keeps power draw and weight down, and removes the privacy pressure of a lens rolling continuously in public.

The final capture modes depend on production testing and the launch notes. As things stand the product is stills-first, and continuous video is not treated as a core feature.

Storage falls from thirty-odd GB to a few GB, and the battery does not have to grow to feed continuous encoding. Both of those savings went into the sensor and the lens.

Flash is also getting more expensive this year, and continuous 4K video is exactly what eats it. Skipping it saves more than space, it saves real money — and that lands in the price you pay.

Because on a sensor this small, stacking the pixel count higher is the easiest and the most useless thing you can do.

On the same area, more pixels means each one is smaller, and how much light a single pixel catches decides the noise in low light and how much highlight and shadow detail survive together. Cram 20 megapixels into the same area and every pixel catches half the light. The spec sheet looks better; the photographs look worse.

So we spent the budget in the opposite direction: a bigger individual pixel. The 4K photographs 12 megapixels produce are more than enough to look at on a phone, post to social platforms, or print at six inches.

Allwinner V883. Quad-core CPU, 4 TOPS of on-device compute.

What actually matters is not those two numbers, but which jobs it puts on the silicon: AI-ISP (noise reduction, wide dynamic range and colour all resolved at the moment of capture), PDAF phase-detect autofocus (raise your hand and press, no waiting while it hunts), electronic stabilisation (you are walking when you shoot, not braced), 4K encoding.

Because taking a photograph never needed AI. The phrase "AI glasses" runs the two together, but technically they are entirely different:

Taking a photograph never touches the second row. The chain is sensor → ISP → encode → write to flash. Not one step needs a network, and not one step needs a large model. So with the connection down, in aeroplane mode, or with the phone not on you, the photograph is still taken and still stored.

All of it is hardware blocks inside the ISP, and none of it is AI:

3A — auto exposure, auto white balance, autofocus (PDAF phase detection).

Correction — dead pixel correction, lens shading correction, black level correction, and the geometric distortion correction an ultra-wide lens has to have.

Imaging — demosaicing, colour matrix, gamma, sharpening.

Noise and dynamic range — 2D/3D noise reduction, WDR multi-frame merging.

Stabilisation — electronic image stabilisation.

Output — JPEG/HEIF encoding, writing to the file system.

Every phone and every camera has all of this. Nobody usually says its name out loud.

"AI-ISP" is a term that misleads easily, so here is exactly what it means.

It means that a few stages inside the ISP — noise reduction, demosaicing, wide dynamic range merging — use small neural network operators in place of classical algorithms. The models are a few MB, and they run on those 4 TOPS.

That is not the same thing as "running a large model on the device". One computes the noise away; the other understands what is in the picture. We do the first. We do not do the second.

So essentially all 4 TOPS on this chip serve imaging. They are not set aside for you to hold a conversation with an AI on your glasses.

All of it is settled in the local ISP, with no connection:

Anything that has to understand content happens on the phone or in the cloud:

Retouching and stylising a shot, identifying a plant or an animal, turning a photograph into a black-and-white line drawing, transcribing and tidying speech, semantic search across the album ("find that ginger cat from last summer").

The glasses have one job: take the picture and the sound cleanly, then hand them over.

What a flagship phone chip is good at is running large models on the device itself. Our AI is not on the glasses, it is on the phone.

So what we want is not a chip that thinks, it is a chip that takes a clean frame — AI-ISP, phase-detect autofocus and electronic stabilisation are the three things that decide whether a photograph comes out. The cost and the power we saved went into the sensor, the lens and the battery.

Fast aperture, ultra-wide, fixed focal length, a multi-element hybrid glass and plastic group.

Fixed focal length: glasses do not need zoom, turning your head is the zoom. Zoom means a motor, a longer barrel, more moving parts — all three add weight, all three drain power, all three are somewhere to break.

Ultra-wide: because you have no viewfinder. When you raise your hand and press, you are not sure where the edges are — go wider and you will not take half of someone's head off. Get the shot first, crop on the phone later.

Fast aperture: it decides whether dusk, indoors and under the trees — the "not that bright but you want the shot anyway" places — are usable at all.

Glass and plastic hybrid: all-plastic elements are cheap, but the edges go soft and pick up purple fringing. Adding a glass element pushes both down, at the cost of a little more money and a little more weight. That is a cost we accept.

150mAh, the same class as mainstream AI glasses.

Measured runtimes for every mode will be published before we ship — standby, how many photographs, how long it records continuously, how long it plays back, each one tested before it is written down. We are not inventing numbers now.

What can be said now is the order of the drain: recording costs more power than photography, not the other way round. A photograph wakes the device for a second or two and drops back into deep sleep; recording keeps the microphone, the encoder and the writes running the whole time. So recording is used in stretches, not left on — if you want it running all day, this is not the pair for you.

Because the battery is one of the heaviest single parts in a product like this, and every step up in capacity presses a little harder on the bridge of your nose.

And a pair that presses is a pair you will not wear every day. A device you do not want to wear has a runtime of zero, however long the number says.

150mAh is enough because of the decision not to do continuous video: the chip never runs flat out for long, power draw is an order of magnitude lower, the battery can be small, and there is no need to add heat-spreading structures and metal parts to shed the heat.

We would rather you charged it once a day than took it off after two hours.

16GB of eMMC, holding 2000 to 10000 4K photographs. The range is wide because you set how big a single photograph is yourself, anywhere from 1.5MB to 8MB. Set it smaller to store more, set it larger to keep the detail.

That storage is shared with recordings. Photographs and recordings are both written to the glasses first and synced later, and once they are synced you can clear the space.

Why not fit more flash we concentrate on stills and do not do continuous video, so 16GB is enough. The hardware serves what the product is for, it is not there to win a spec comparison — the budget we saved went into the materials and the craft of the frame itself.

No. Photographs are stored on the glasses first and synced later.

Yes. It lights when a photograph is taken and goes dark when one is not, sitting next to the camera, facing outward, not toward your eyes. It is not a setting you can turn off.

We changed our minds on this one. On an earlier recording-only design we took every light off the device, on the grounds that those glasses physically cannot record the person beside you — no problem, so no signal needed.

A camera has no such property. A lens captures whatever it points at, and you cannot design one that photographs only what you meant to look at and never anybody else. The boundary can only be drawn by people and by rules, which means the people beside you have to be able to see the state. The premise changed, so the conclusion had to change with it.

The camera points where you are facing and sees what you see. It is for outdoors, and for when you are on your own.

Please follow the rules of wherever you are — exam halls, secure sites and some museums do not allow camera devices at all.

No.

Both microphones sit on the frame front: the main mic is at the lower edge of the left rim, dead centre, its port facing down toward your mouth, 4–7 cm away; the reference mic is at the top of the right rim, port facing up and away from your mouth, and much farther from it. The difference in level between the two is what decides; someone half a metre away never clears the threshold.

This is not a software filter, it is where the holes are. A physical guarantee is worth far more than a software promise — a software promise can be quietly changed in the next firmware update. Geometry cannot.

Quietly enough that the person half a metre away hears nothing, and it still picks you up clearly. That is what those 4–7 cm between the main mic and your mouth buy you.

Because the temples are too far from your mouth. Sound pressure falls off fast with distance, and the gap between a few centimetres and a dozen is not a small one — it is the difference between position alone keeping other people out and not.

Put the mics on the temples and you are left guessing, in software, which words were yours. When the guess is wrong, you have no way of knowing it was wrong.

On the glasses' own storage. Nothing touches Bluetooth or the network while you record.

When it syncs, and where to, is your call. What you said belongs to you.

The glasses are built around two-way privacy: a child can murmur or whisper their own class notes and ideas without the people beside them easily hearing; the glasses lean on the geometric difference between the near-mouth main mic and the reference mic to capture the wearer and leave the teacher's and classmates' conversation out.

Using them at school still means following school rules, classroom discipline and local law; respect what other people want when you take a photo. The privacy design is not a reason to work around the rules.

Mainly the frame and everything that holds it on your face: a TR90 frame, titanium-alloy hinges and trim, liquid-silicone air-cushion nose pads, conventional optical lens fitting, and the light weight and impact resistance that children and sport ask for. Lenses are configured separately according to what you choose.

Because a device you do not want to wear is worth nothing, however many features it has.

Frame, temples, hinges, nose pads — all built to the standard of the high-end sports and children's eyewear sold in the US. Take every electronic part out and it is still a thousand-yuan pair of glasses — good enough to keep on indoors, good enough to keep on out in the field.

To be precise, what we use is a hybrid: TR90 for the body, titanium alloy for the hinges and the trim. Not solid titanium, not plain plastic. The next question has the full comparison table.

There are three reasons the body is not solid titanium. The first two are engineering. Only the third is weight.

One: there is a microphone hidden in the front rim, and electronics in both temples. Routing flex cable through a metal frame is a harder problem, and we could not find what it would buy us.

Two: metal fights the antennas. These glasses carry Wi-Fi and Bluetooth LE, and antennas have to radiate outward. A metal frame shields them and detunes them, and keeping them alive would mean a stack of structural compromises — compromises that cost more than titanium is worth.

Three: TR90 fits this job better. It is the nylon used in high-end American outdoor sports eyewear: very light, very tough, it springs back under load instead of taking a set; it does not conduct heat, so it is not hot in summer or cold in winter; it contains no nickel, so it rarely sets off allergies. Not the cheap plastic the word "nylon" brings to mind.

What titanium alloy really has going for it is that you can warm it to fine-tune the fit, and that particular sense of luxury. But this is a thing you wear a dozen hours a day and take outside to move in — what we want is durable and light.

Because the two are solving different problems. Solid titanium is the best answer for a conventional pair of glasses, and what we have to fit is a pair with a battery, antennas, speakers and sensors inside. On four counts the hybrid is the better fit.

So what is the titanium still there for? It stays in the two places it most belongs: the hinges and the trim. The hinge is where glasses actually break, and that spot wants metal's strength and precision; the trim is where the material quality is made visible — the shine and the feel of metal are things a moulded part cannot imitate.

In a line: TR90 takes the structure and the electronics, titanium takes the load and the finish.

Because what the two need is entirely different: one puts function first, the other looks.

What TR90 has going for it: extremely high flex and impact resistance, springing back after being bent, and hard to break by dropping, sitting on, twisting or knocking; usually thirty to fifty percent lighter than acetate; it does not shatter into sharp fragments, which lowers the risk of a second injury to eyes and face; it stands up to sweat and heat, so it does not deform when you perspire or leave it somewhere hot; it contains no metal and no nickel, so the allergy risk is low. TR90 was designed for sport and high-impact use in the first place.

What acetate has going for it: layered, textured colour with real depth of gloss, and a substantial, expensive feel in the hand; warm it and it adjusts easily, so an optician can tune the fit precisely.

What acetate costs you: harder and more brittle, so it cracks or snaps under impact; noticeably heavier; more prone to deforming in heat. Not suited to frequent hard exercise, and not suited to the rough handling a child gives things.

Neither is absolutely better than the other; they are simply for different situations. What the high-end sports brands use is usually a better TR90 formulation, not ordinary moulded plastic.

Thin, and wide — the same feel as the temples on a pair of fashion sunglasses. It is a balance in three directions.

Thin so it does not look clumsy. Electronics packed into a temple turn into a bulge more easily than anything else, and the moment it bulges it stops reading as eyewear.

Wide so there is somewhere to lay the electronics out flat, instead of stacking them upward. For the same volume, spread out looks far better than piled high.

Wide also settles something else along the way: it shades the outer corner of the eye. Ultraviolet slanting in from the side is the part most glasses miss, and a wide temple blocks it physically.

But we do not wrap the whole way round. Wrapping all the way, the way proper goggles do, blocks more — at the price of a frame that has to be thick and heavy. Block what needs blocking, and do not pile weight on for the last little bit.

Liquid silicone, air-cushion structure, swappable for a different height. Sports eyewear generally avoids metal nose pads, for five reasons.

One: they slip once you sweat. A metal pad is hard and smooth on the surface, and heavy sweating drops the friction sharply, so the glasses slide down. Soft silicone does the opposite — wet, it grips harder.

Two: safer in an impact. In hard exercise or a fall, a metal pad easily concentrates pressure on the bridge of the nose and can injure it; a soft pad cushions instead.

Three: more comfortable. Worn hard for hours, metal pads leave dents and red marks either side of the nose, and can simply hurt. Soft silicone has more contact area, sits closer, and spreads the pressure more evenly.

Four: a different kind of structure. Sports eyewear uses one-piece moulded soft pads, height-adjustable rubber pads, or nothing but the fit of the frame itself — designs that suit fast movement, sweat and vibration.

Five: allergies and durability. Some people react to metal, and skin is more sensitive during exercise; soft silicone also will not oxidise and blacken.

Everyday metal frames use metal pads for adjustability and for the premium look. What we put first is grip, cushioning, comfort and safety.

Yes, and the spares are in the box. Bridge height varies enormously from person to person, and one size cannot possibly suit everyone — a high bridge takes the low pad, a low bridge takes the high one.

This is also the main mechanism by which we can serve Western and Asian faces at once: the biggest difference between them is not head circumference, it is bridge height and facial depth.

Our thinking on the temples is brandless: no brand name, just the simplest possible logo mark — and that ring stands for a black hole.

There is space left beside it. For ¥100 you can add a small emoji icon of your own there — pick one from our set, or design your own and hand it to us.

The position is fixed, next to the logo. Like the logo, it is electroplated on, not a sticker.

Leave a note with your order. If you designed it yourself, send us the image and we will confirm whether it can be made and what it will look like before starting.

Because with baked enamel, one colour and five colours are not the same order of difficulty. Concentrating the effort on a single colour at launch is what holds the consistency of the finish.

Other colours will come later, but not in this first batch.

Two reasons.

It is the one colour that does not enter into a contest with skin tone. A dark frame sets up a hard contrast against light skin; a pale frame gets swallowed by dark skin. White is the colour that goes wrong at neither end — fair skin or deep, a white frame just frames the face cleanly. For a product that has to face Western faces and Asian faces and every skin tone at once, that counts for far more than "attractive".

It is also the one that punishes the process hardest. The slightest colour variation, orange peel or paint pooling at an edge has nowhere to hide on white. We use the same baked finish as that classic white on the Apple phone — choosing white means knowingly pushing our own yield down a notch.

The measured weight of the standard-size production version will be published before the official launch. The product is still built around a child wearing it for long stretches, holding the weight down through the TR90 body, the flexible temples and a light structure.

Mostly not through materials. Through the decision to take stills only, and not long video.

Continuous 4K encoding keeps the chip at full load for a long time; power draw goes up, the battery has to grow, the heat has to be dealt with — and the battery is one of the heaviest single parts in a product like this, with the heat-spreading structure and metal parts as a second bill. Stack those three and they weigh far more than the camera module itself.

We only take stills, so the chip can drop back into deep sleep between two shots, an order of magnitude lower in power. The battery does not have to grow, and nothing has to give way to cooling.

Rinse first, then wipe. Never wipe dry. The most common reason a lens gets scratched is being wiped while dust is still sitting on it, grinding that dust across the coating. Rinse with cool water first, then dry with a cloth. Do not use alcohol or household glass cleaner, which will strip the coating off.

Do not leave the glasses on a car dashboard. Heat softens TR90 and warps the frame, and a warped frame moves the main mic away from your mouth — that one distance is the thing this product depends on most.

The microphone port is a very small hole with a metal mesh behind it. If a recording ever starts to sound muffled, look at that hole on the lower edge of the left rim first. Rinse it; do not poke anything into it.

Razzhood comes in one standard size only. Frame width 132mm, frame height 42mm, lens width 48mm, bridge width 17mm.

Sprung temples and a temple profile designed to widen the fit range mean the standard size suits most children, and plenty of adults too. Whether it suits you still comes down to your actual face width and how it feels on.

That's a different road, and a reasonable one — multiple shapes and colours solve the problem of taste, so people with different styles can each find their own.

We spent the same tooling budget on whether it fits. The reasoning: this pair isn't purely a fashion object. It has to stay on for a dozen hours a day, it has to stay on during outdoor sport, and it has to sit on a six-year-old. In those situations, staying on beats looking good.

And because we have only one colour, we can get the paint on that one colour right. For a first release, do one thing, and do it all the way.

Measuring your head circumference is the most accurate. Or send us the string of numbers printed inside the temple of the glasses you wear now and we'll match it for you — that string is usually "lens width □ bridge width – temple length".

It does, mainly thanks to the swappable nose pads. The biggest difference between the two isn't head circumference, it's bridge height and facial depth — a high bridge takes the low pads, a low bridge takes the high pads, and the same frame lands in the right place on either face: no sliding down, no pressing on eyelashes.

Yes. The shape sits between a square and a round frame, so it reads neutral; the standard size fits most children through its sprung temples and temple profile, and plenty of adults as well.

No — that's one of the reasons we chose white. A white frame doesn't play the contrast game with skin tone; fair or dark, it simply frames the face cleanly.

And pale rose gold is a warm colour: on any skin tone it lifts, it doesn't weigh down.

Usually the hinge. So the standard size's hinge is engineered to sports-eyewear durability, with titanium alloy carrying the constant opening, closing and load.

Trivex is one of the lens materials we recommend first for children and for sport, because it's light, impact-resistant and optically strong. But it isn't an included lens — buy according to the prescription plan you actually need.

Pale rose gold against a white frame is striking and warm, and it fits the energy of children and teenagers, which is why it's the default recommendation. It isn't included by default, and it isn't the only option.

Pale rose gold is a light tint, so it holds up indoors and out and over a phone screen. The actual UV, blue-light, impact and prescription performance depends on the lens material and coatings you finally choose — colour alone doesn't tell you.

Mostly artificial blue light.

Blue light from the sun is actually good for you, and at night there's no sun to give you any, so it doesn't touch melatonin. The problem is the short wavelength of artificial blue light — day or night, we think you should block it.

At night, blue isn't the only thing to block. It's the whole short end: blue, green and violet.

Some lenses on the market advertise that they "filter the harmful blue light and keep the beneficial blue light", sorting it by wavelength. That doesn't match the thinking in the American biohacker community — the consensus among US biohackers and longevity researchers is that artificial blue light is bad for the body full stop, because it affects not only melatonin in the eye but the microbial layer of the skin.

To be clear: that is that community's position, and the position we adopted when making product decisions. It is not a settled medical conclusion.

It is. To block blue and green at night, deep red and true red genuinely work best.

We didn't pick them, for a very practical reason: with deep or true red on at night you can barely make anything out, and in daylight they look bizarre, because the colour is simply too red.

Pale rose gold is the compromise that holds up day and night, indoors and out.

Because you're not going to take them off when you walk through a door.

Sunglasses have exactly one mode: on outside, off inside. That's precisely why a sunglass lens can be as dark as the sun demands. This pair has a set of headphones and a camera in it, and that mode breaks in two places.

Indoors you can't take them off. You might be mid-call, or halfway through listening to something. Taking the glasses off means cutting it short — and forcing someone in a doorway to choose between hearing and seeing clearly is a miserable thing to do. So the lens has to hold up under ceiling lights, and a dark tint can't.

Outdoors you still have to look at your phone. Pulling up the shot, going through the album, changing a setting — all of it happens outdoors, in sunlight, on a screen. A dark lens pushes the glasses onto your forehead every single time — and the moment they go up, the main mic leaves your mouth. A light lens shades your eyes without shading your screen.

In bright light a light tint does more than that sounds like: it takes the glare off, takes it off until you stop noticing it's there. For a pair of glasses you have no intention of removing, that's what you actually want.

There is: photochromic lenses. That's the complete answer to the doorway problem — clear indoors, sunglasses outdoors, nothing to do.

The molecules in a photochromic lens change shape when ultraviolet hits them; in that shape they absorb visible light, and the lens darkens. Take the UV away, they relax back, and the lens goes clear again. No power, no switch.

They suit this pair especially well, because you never have to push the frame onto your forehead — and the moment you do, the main mic leaves your mouth. Photochromics can be made with a prescription too.

Because you're going to look at your phone.

Polarisation filters out the light that reflects off flat surfaces at a particular angle — water, wet tarmac, a car bonnet. For fishing and driving that really is useful.

But phone and laptop screens emit polarised light to begin with. Put a polariser in front of one and the screen dims; turn your head and at some angles it goes black outright. Every sync, every look at a photo, the lens is fighting you.

Polarisation was built for looking at water. This is a product built for looking at a phone.

We asked a lot of fashion creators, and the answer came back consistent and blunt: a gradient reads middle-aged. It's a permanent band of dark, and it shows up in every photo of you.

Photochromic is the same idea without that baggage — most of the time it's a clear lens, and when the sun comes out it's a pair of sunglasses. Nothing about it is permanent.

The lenses aren't tied to any one option. Take it to a professional optician and choose plano, short-sighted, long-sighted, astigmatic, progressive, photochromic, tinted or high-index lenses.

You assume it's the late nights, you assume you slept badly. In fact you may already be slightly long-sighted.

For some people it starts at thirty-eight, for others forty-five, for others fifty; it varies enormously. And the awkward part is this: if you need a prescription in your thirties or barely past forty, you don't want anyone thinking you're wearing reading glasses.

But what you're wearing is a pair of AI glasses. That changes the whole thing.

Get tested at an optician — that's the most accurate. Or, simpler: try the off-the-shelf ones in the shop, and whichever feels comfortable is the one for you.

Long-sight prescriptions don't usually shift much, and the spread between most people isn't large either — which is very unlike short sight.

The real problem is that if you never wear them, you never notice. Losing small print doesn't arrive as the thought "I should get glasses". It seeps into your work, your studying and your life as a slight dullness: reading the menu twice, skipping the manual, nudging the phone's font size up and up, finding it harder and harder to read at night.

Both work.

Progressives: the distance prescription (or plano) up top, the reading prescription at the bottom. One pair, two jobs.

Two pairs: one for distance, one for close up. Some people simply never get on with progressives — the edge of the field swims, and going down stairs you have to tilt your head to find the angle. So two pairs is where plenty of people end up.

By material and prescription, from ¥60. Tinted is 1.2× the clear price, photochromic 1.5×. The clear tier includes blue-light and UV coatings.

0–300 degrees: 1.56 standard resin from ¥60 / 1.60 (MR-8) from ¥100 / Trivex from ¥180.

300–600 degrees: 1.60 (MR-8) from ¥100. 500–800 degrees: 1.67 (MR-7) from ¥180. Above 800 degrees: 1.74 (MR-174) from ¥360.

Lenses of the same specification usually run ¥100 to ¥2,000 in Chinese high-street shops, and $50 to $800 at LensCrafters and Walmart Vision Center in the US. That's a reference range from published price lists, for comparison only; it isn't anyone's actual quote.

Astigmatism, progressives and unusual pupillary distances are priced separately. Send us the prescription and we'll confirm everything before it's made.

You can, and we kept that open deliberately.

The frame is built on conventional optical geometry, not as a sealed part that only takes factory lenses. Walk into any professional optician with it and every lens option they can do, they can do on this pair.

Tell them it's a TR90 front in ordinary indoor-eyewear proportions, and ask them not to force the rims open while the temples are attached.

Sphere (SPH), cylinder (CYL) and axis (AXIS) for each eye, plus pupillary distance (PD). Your optician has them, and most prescriptions print them right on the sheet.

Then tell us whether you want that prescription clear, tinted or photochromic. If you're not sure, don't choose yet — leave a note with the order, or just send us a photo of the prescription.

Three things worth knowing before you order.

Behind a car windscreen they barely darken at all. Laminated glass blocks most of the ultraviolet, so the lens never gets the signal. If you'll mainly use them while driving, go straight to a fixed tint.

Temperature changes them. In the cold they go darker and clear more slowly; in the heat they never reach their darkest, but they clear faster.

They never go completely clear indoors — a faint residual tint stays.

No. UV protection comes from the lens material and its UV design, not from how dark the tint is. A dark lens without proper UV protection can dilate your pupils and raise the risk instead.

Razzhood frames take a range of lenses. When you choose, confirm UV protection, impact resistance, prescription range and coatings with a professional optician; not every available lens carries identical specifications.

You can. The frame is built on conventional optical geometry, so lenses can be replaced or added whenever you need. What it costs depends on the lens material, the prescription, the coatings and the fitting service.

You look at the code on the register, and the payment is done. No phone out of your pocket, no unlocking, no app to open.

Inside China, Alipay is so far the only one to have built this into AI glasses. Outside China, no payment app has brought it to AI glasses at all.

With Nihao Pay as our partner, it works in all four markets at once.

“First pair” is what we knew to be true at the time of writing.

It is a deep partner of China UnionPay.

Its CEO, Rufei, projects US$10 billion in transaction volume on the platform in 2026.

That is why we picked them as our payment partner: making pay-with-a-look work across China, the United States, the Middle East and Southeast Asia takes deep integration on the clearing side, not just wiring up a QR code.

The US$10 billion is their CEO's projection, not a number that has already happened.

Nihao Pay is an ecosystem app on Razzhood.

At the same time, Razzhood is an ecosystem partner inside Nihao Pay's payment network.

Each is a link in the other's ecosystem.

This first batch is built for users in mainland China, and the interface is Chinese only.

Chinese speakers abroad can still buy a pair and use Nihao Pay for small no-PIN payments. Shipping outside China we work out one on one once you join the community.

The platform is open: phone apps, desktop apps, even pure web apps can join.

The glasses capture image and sound cleanly, and everything after that goes to the people who specialize in it — finishing photos, taking notes, keeping records, payments. We don't intend to build all of that ourselves. The full list will be published as it fills out.

Because they are two completely different capabilities.

Capturing a clean image comes down to the chip, the sensor, the lens and the structure — that is hardware, and hardware is our job.

Turning a raw frame into a photo you would actually post comes down to models, taste and years of iteration — that is software, and people have been at it for a long time.

If we built that layer ourselves we would most likely lose to them, and close the door on the ecosystem while we were at it.

The open ecosystem can support apps for children's creative work, photo organizing, voice notes, study records, voice-driven programming and more. The learning and development material for that lives on the Vibe Coder Basic and Vibe Coder Advanced pages.

The interface documentation and the development kit: how to connect, how to pull a photo, how to pull a recording, how to trigger a shot. Developers get the same set we use ourselves. The documentation goes public before shipping.

Other people's things. A user's photos and recordings belong to the user — not to us, and not to any third-party app. What a developer receives is the copy the user has authorized, not a back door.

Yes. The bar for making a working app has come down: parents, product managers, designers and children can all reach a prototype with Vibe Coding.

What actually needs setting up is the server, the accounts, the data storage and the connection to the glasses. Vibe Coder Basic and Advanced cover the path from prototype to finished product, one stage each.

Because the hard part isn't building it. It's finding the first few hundred users from a cold start.

An app made specifically for children aged six and up that has several hundred real users the day it launches is a valuable thing — and that is exactly what we can offer. Our goal is to pre-sell more than ten thousand pairs within three months, on top of the channel the Musk Institute and the Razzhood community give us.

The interface documentation and the development kit go public before shipping, and resident engineers can help with backend setup. We review every app before it enters the ecosystem, and the ones for children most of all.

Ten thousand pairs is our goal, not something that has already happened.

We don't plan to build these ourselves, but every one of them is buildable:

Plants and animals in the fieldA child sees a plant they don't recognize up in the hills, presses once, and comes home with an illustrated list of names.

Photo notesA line or two on every picture, spoken or typed.

Outdoor timeAn app that does exactly one thing: track how long you are really outdoors each day.

Food logTwenty shots across an hour-long meal turn themselves into a food diary, which you can also feed into a health analysis.

Retail price is ¥1,200 a pair.

A ¥200 deposit per pair reserves it and is non-refundable; the balance of ¥1,000 a pair is a second, separate payment before shipping, and you can reserve several pairs at once. The deposit is paid on this site by card, Alipay or WeChat Pay. The pale rose-gold lens is the default recommendation, not a default gift.

The launch date is to be confirmed and the ship date is to be confirmed. Once they are set we will publish them on the purchase page and in the formal order terms.

Both the launch date and the ship date are still to be confirmed, so three months is not a figure to count on. Once the schedule is published, the purchase page and the formal order terms are what govern.

If you choose custom prescription lenses, each pair has to be cut individually to your optometry values. Orders that need no custom lens follow the production and shipping schedule.

This first batch is distributed in mainland China only. If you are abroad and want a pair, you can reserve one now at the same price; enter your real address.

Two weeks before shipping we will confirm the overseas details with you one on one; at that point extra shipping, duties and other related fees become payable.

One advantage of ordering from China is the lens price. Our custom lenses usually cost less than a bricks-and-mortar optician in the United States, and you can order several sets at once so shipping and duties are only paid once, then have a local optician fit them later.

All of the above is handled by a person, so email us to confirm.

The base package holds the glasses, replacement nose pads, a case and a cleaning cloth. The charging accessories included follow the official packing list. Lenses are fitted according to the prescription option you choose; the pale rose-gold lens is not included by default.

No — this is neither a co-brand nor a tie-up. For every pair of glasses sold, Razzhood donates to the Musk Institute as agreed; beyond that, each side's own brand, products, courses and events are governed by that side's official statements. Razzhood has no commercial relationship with SpaceX, Tesla or xAI.

The first 1000 pre-orders receive a place in the Musk Institute's first cohort, and the place is transferable. The Institute's activities, applications and participation rules are governed by the Musk Institute's official page.

The Musk Institute studies Musk's approach to innovation, first principles and cross-disciplinary practice, and turns that thinking into learning material for teenagers and future founders. Its courses, events and partnerships are governed by its official page.

For every pair of Razzhood glasses sold, a donation goes to the Musk Institute as agreed, with no sales threshold and no cap. The Musk Institute studies approaches to innovation, first principles and cross-disciplinary practice, and turns that thinking into learning material for teenagers and future founders.

The first 1000 pre-orders receive a place in the Musk Institute's first cohort, and the place is transferable. Student activities, eligibility and everything that follows are governed by the Musk Institute's official page.

The current offer treats no travel as a default benefit. If the Musk Institute organizes something in future, the route, the cost, the eligibility and the liability are governed by a separate official event description and agreement.

No Texas viewing date or launch is confirmed as a Razzhood purchase benefit. Any future event is governed by the organizer's official announcement.

The current offer does not include a viewing trip, so there is no confirmed list of what is included and what is not. If a standalone event happens later, the sign-up page will set out the costs and the responsibilities.

No such promise has been made. Razzhood should not be read as a project Elon Musk takes part in, attends or endorses.

No. Razzhood has no commercial or official event relationship with SpaceX.

The current offer does not include a launch viewing. If a standalone event happens later, its rescheduling, cancellation and refund rules are governed by the event agreement.

The current offer includes no travel benefit that requires a visa. If a standalone international event happens later, participants are responsible for confirming their own visa and travel conditions under the event's terms.

Launch Partners are creators and community organisers who take part in Razzhood's early community building, co-created content and user feedback. The exact number, the selection process, the benefits and the responsibilities are set by the official programme description.

The brand invites them directly, based on their work, their experience running a community, their values and what they have actually contributed. The final rules, the number of places and the timeline are set by the Launch Partner programme when it is published.

Launch Partners take part in the brand's early community building; Musk Institute students take part in the institute's teaching and events. The two roles, their selection criteria and their benefits are independent of each other, each governed by its own official rules.

Keep publishing original work on AI, glasses, learning for children and teenagers, or Vibe Coding, and send us a note through an official channel. The brand reaches out to creators whose work and community contribution fit.
