Every pair of AI smart glasses you can actually buy today does three things: takes photos and video from your point of view, plays audio without plugging your ears, and answers when you talk to it. None of the models in this guide has a screen. Anything you have seen suggesting otherwise was a concept video.

How we picked the models in this guide
The first filter was brutal and it removed most of the field: the glasses had to have a live product page we could check by hand on the day of writing. Half the AI eyewear you read about is a Shenzhen prototype, a Kickstarter promise, or a US-only launch. Those are out.
We have not worn any of these. Everything below comes from the manufacturers' own spec sheets, from the specialist press (Tom's Guide, Android Central, Android Police, 91mobiles, Road to VR) and from long-term reviews written six months after purchase, which are the only ones that tell you what happens once the novelty burns off.
Four things carried weight, in this order: what the assistant genuinely does rather than what the keynote promised, how long the battery lasts when you are actually recording, how the recording indicator handles the privacy of everyone else in the room, and what it costs to get your prescription into the frame. Star ratings and review counts were used to shortlist and are not quoted here. Announced-but-unshipped features counted for nothing, and on this product category that turned out to matter.
What the AI on a pair of glasses actually does
On the three Meta models here, the assistant lives in the frame and wakes on your voice. Ask it to take a photo, start a clip, describe what is in front of you, or translate. Live translation covers six languages and works with pre-downloaded packs, so it keeps going in aeroplane mode. You can answer a WhatsApp call, fire off a message, start a playlist. The phone stays in your pocket.
Now the part the ads skip. There is no display. No floating arrows on the pavement, no subtitles hovering beside the person speaking; translation is read into your ear and that is it. The scene descriptions are the weakest link. One six-month review asked what kind of tree it was looking at and got back that it was "a tree with green leaves". Live streaming, announced at launch, still had not shipped half a year later.
The fourth pair here plays a different game, and it deserves credit for saying so. The Xiaomi has no on-board AI whatsoever. It has microphones, open-ear speakers, and a gesture that wakes whichever assistant already lives on your phone, whether that is Gemini, Siri or Alexa. Useful shortcut, not a machine that sees.
Rule of thumb: no camera means the "AI" is your phone's AI, routed through a nicer microphone. That difference is worth roughly two hundred euros.
The recording LED, and everyone else in the room
Start a recording and a white LED lights up on the frame. It is the only warning the people around you get, and it works right up until it doesn't.
The catch is that the LED can be removed. Paid services exist that will disable it, and the response has been predictable: Android apps have appeared that detect nearby glasses in the act of recording. This is not a niche worry. It is why gyms, schools and a growing number of offices have started treating camera glasses as unwelcome.
Filming identifiable people, and especially publishing that footage without consent, carries legal consequences in most of Europe and varies by state in the US. Check the rules of the building before you walk in wearing these.
Claimed battery life versus the battery life you get
The second-generation Ray-Ban Meta claims up to eight hours of typical use, against roughly four on the first generation. That single number is the whole reason this generation is worth discussing. Fast charging gets you to 50% in twenty minutes, and the case holds another 48 hours.
"Typical use" means occasional music and the odd photo. Record video and the eight hours evaporate, because video is the expensive part, and there is a hard ceiling per clip anyway: five minutes, dropping to three at 3K. Oakley quotes the same eight hours, with a 230 mAh cell found in an iFixit teardown and up to 19 hours on standby.
| Model | Claimed runtime | What halves it |
|---|---|---|
| Ray-Ban Meta Gen 2 (Wayfarer, Skyler) | Up to 8 h typical use | 3K video, continuous live translation |
| Oakley Meta HSTN | Up to 8 h, 19 h standby | Long clips mid-activity |
| Xiaomi Mijia Smart Audio Glasses | Up to 12 h of music | Long calls (drops to 8-9 h) |
Ray-Ban Meta Gen 2: Wayfarer or Skyler
Identical hardware, two different frames. A 12 MP ultra-wide camera, video up to 3K at 60 fps, five microphones, 32 GB of on-board storage, IPX4 splash resistance. What separates them is the shape of your face and the light you spend your day in.
The Wayfarer is the safe answer, and in the clear-lens version it is the one you can keep on indoors without looking like you forgot to take your sunglasses off. List price starts around $379.

- Meta AI on board: voice commands, scene description, live translation in six languages
- Up to 8 hours of typical use, 50% charge in 20 minutes, 48-hour case
- 32 GB of on-board storage and five microphones
- Clear lens, so it stays on indoors
| Camera | 12 MP ultra-wide |
|---|---|
| Video recording | 3K at 60 fps, 5 min per clip |
| Battery life | up to 8 h typical use |
| Ai assistant | Meta AI on board, translation in 6 languages |
| Water resistance | IPX4 |
| Recording led | yes, white LED |
Double the runtime of the first generation, genuinely quick top-ups, a clear lens that works indoors, native WhatsApp and Instagram integration, and enough storage that you stop thinking about it.
Video comes out 4:3, which anyone shooting for a widescreen edit will notice within a day. Clips cap at five minutes. The companion app has drifted into being an AI content feed with a glasses tab attached, and iPhone music support is partial: YouTube Music, for one, isn't covered.
The Skyler is the narrower, lighter frame, built for smaller faces; the cat-eye shape sits where a Wayfarer would push against your temples. This version ships with Transitions lenses that darken outdoors and clear up inside, which is the most convenient thing on this page and also pushes the list price to around $459.

- Transitions lenses: clear indoors, dark in sunlight
- The same 12 MP camera and 3K video as the Wayfarer
- Meta AI, live translation and WhatsApp calls without touching the phone
- Up to 8 hours of typical use with the charging case
| Camera | 12 MP ultra-wide |
|---|---|
| Video recording | 3K at 60 fps, 5 min per clip |
| Battery life | up to 8 h typical use |
| Ai assistant | Meta AI on board, translation in 6 languages |
| Water resistance | IPX4 |
| Recording led | yes, white LED |
A 48 g acetate frame with a genuinely smaller fit, Transitions lenses that solve the in-and-out problem, and none of the Wayfarer's hardware sacrificed to get there.
You pay a substantial premium for the photochromic glass alone, and adding a prescription means having that lens remade from scratch, with a quote that starts high. Transitions barely darken behind a windscreen, because the glass filters the UV that triggers them. The narrow frame also suits fewer faces than the Wayfarer.
Oakley Meta HSTN, the pair you take running
Same brain, different chassis. The HSTN is built around sport: a wrap fit, interchangeable PRIZM or Transitions lenses, the 12 MP camera with 3K video, five microphones, IPX4. It launched at $399, and the full collection runs to six frame-and-lens combinations, all of them stated to accept prescription lenses.
On a run or halfway up a climb they are worth a look for one reason: hands-free point-of-view capture is the single job these glasses do that a phone genuinely cannot. In a meeting room, on the other hand, a wrap-around sports frame announces itself.
Illustrative image- Wrap sport fit, built for running and cycling
- 12 MP camera with 3K video and five microphones
- Up to 8 hours of typical use and up to 19 hours on standby
- Six frame and lens combinations, all stated to accept prescription lenses
- Meta AI with voice commands and live translation
| Camera | 12 MP ultra-wide |
|---|---|
| Video recording | 3K, 5 min per clip |
| Battery life | up to 8 h, 19 h standby |
| Ai assistant | Meta AI on board, translation in 6 languages |
| Water resistance | IPX4 |
| Recording led | yes, white LED |
Far better stability during activity than any of the Ray-Ban frames, a mature Oakley lens ecosystem behind it, prescription compatibility stated across the whole range, and long standby.
IPX4 covers splashes and sweat, not heavy rain, and certainly not a dunking. The frame is loud in the wrong setting. And it launched twenty dollars above the Ray-Ban.
Xiaomi Mijia Smart Audio Glasses: no camera, no ambiguity
This is a step down in price and, refreshingly, a step down in pretence. No camera means no LED problem, no changing-room problem, and no explaining yourself. They weigh 27.6 g, carry an IP54 rating against dust and splashes, claim up to 12 hours of music, and settle nearer 8-9 hours on calls according to one detailed European review. In Europe they list at €179, or €199 for the titanium version.
What they do: music, calls, notification read-out (still in beta) and waking your phone's assistant. What they don't do: everything else. One flaw worth knowing before you buy: waking Gemini produces no confirmation chime, so you talk and hope. Outdoors, the volume runs out of headroom on a busy street.
Availability is the honest caveat for readers in the US: Xiaomi's eyewear is straightforward to buy across the EU and hit-or-miss on Amazon.com, where it turns up through third-party sellers if at all. If you are shopping stateside and want camera-free audio glasses, treat this as the template rather than the purchase.
Illustrative image- No camera at all: audio, microphones and your phone's assistant
- 27.6 grams with 5 mm temples, IP54 rated
- Up to 12 hours of music claimed, 8-9 hours on calls
- Four microphones with wind noise reduction
- Xiaomi Glasses app for gestures, dual connection and notification read-out (beta)
| Camera | none |
|---|---|
| Video recording | no |
| Battery life | up to 12 h of music |
| Ai assistant | phone assistant only (Gemini, Siri, Alexa) |
| Water resistance | IP54 |
| Recording led | not needed: no camera |
A third of the price of the Meta models, feather-light, a full day of runtime, IP54, and the quiet advantage of never having to answer the question "are you filming me?"
No camera, no on-board translation, no scene description. The AI belongs to your phone. Not loud enough on a busy street. Notification read-out is undercooked. Lenses have to be swapped at an optician, so get the quote first.
Prescription and sun lenses: the bill nobody budgets for
This is the line item that quietly doubles the spend. If you wear glasses, you have three routes. Ray-Ban now sells Meta Optics frames designed from the start for correction, and in Italy they arrived from €469 for the frame alone, with lenses quoted separately by the optician and climbing with high index, varifocals and coatings. Expect the same structure elsewhere.
Route two is fitting prescription lenses into a Meta or Oakley frame you already own. Oakley states compatibility across all six HSTN combinations, which is more than the competition commits to. Route three applies to the Xiaomi and is much cheaper, because underneath the electronics it is an ordinary frame.
Sunglasses invert the logic. Transitions add roughly eighty euros to the list price and save you carrying two pairs, but they underperform in a car, where the windscreen blocks the UV they need. Anyone who drives a lot is better off with a fixed dark lens and a separate pair for reading.
When it's worth buying
Gen 2 has been on sale since September 2025 and street prices have drifted well below list on both sides of the Atlantic. There is no urgency here, and November promotions on this category have been unusually aggressive.
One thing not to do is chase the discounted first generation. Four hours of battery against eight is the difference between a thing you wear all day and a thing you put on charge at three in the afternoon. The saving does not survive contact with that.
And if you are mostly buying these for music, stop. They cost three or four times a good pair of headphones and sound considerably worse; our guide to noise cancelling headphones for study and focus covers where that money goes instead.
Don't buy them if…
If you want isolation to work or study, these are the wrong product by design. Open-ear audio leaks outward and lets the world in; the earbuds versus over-ear comparison is the better starting point.
If you are waiting for a display, keep waiting. Screen-equipped models exist, they cost substantially more, and European availability is still thin.
If you work in a hospital, a bank, a plant, or anywhere cameras are simply not allowed, a lens in the middle of your frame is a daily obstacle. The Xiaomi sidesteps the whole argument.
And if you shoot for a living, five-minute clips from a 4:3 sensor are not an action camera. They were never meant to be.

Our verdict
For most people the right pair is the Ray-Ban Meta Gen 2 Wayfarer with the clear lens. It is the one you keep on indoors, it carries the doubled battery that finally makes this category usable, and it undercuts every Transitions option here.
Narrow faces, and anyone in and out of buildings all day, should take the Skyler with Transitions and accept the premium. Buy for running, cycling or skiing and the Oakley Meta HSTN is the only one that stays put. Want music, calls and a voice assistant with no camera on your face? Spend a third as much on the Xiaomi Mijia Smart Audio Glasses. Fewer tricks, and nobody edges away from you at the bar.
