RayNeo iO vs Ray-Ban Meta Gen 3: which one to buy
The RayNeo iO went on sale in September and the Ray-Ban Meta Gen 3 were announced a few weeks later at Connect. They are the newest thing you can buy, they cost roughly the same and a lot of people are putting them side by side. The catch is that they do opposite things: pick by price alone and you will end up with the wrong pair.
RayNeo iO from 549 € · Ray-Ban Meta Gen 3 from 449 €.
The one sentence that decides it
The iO shows you things. The Gen 3 sees things.
The iO has a display in the lens and no camera. The Gen 3 has a 12 MP camera and no display: whatever it answers, it says in your ear. Nothing on the market does both well at this price, so that is the decision — there is no other.
What you see: the iO display
A monochrome green waveguide, 1,300 nits, a 23.5-degree field of view and 97% transparency. In plain English: you read crisp text — a notification, a turn-by-turn arrow, a translation subtitle — floating in front of you, and you still see the world behind it perfectly. It is not augmented reality with 3D objects, and it does not pretend to be.
What it does best is translate: 55 languages, 109 accents and roughly one second of latency, with the text appearing in the lens while the other person is still talking. Nothing else in our catalogue comes close at this level.
What it records: the Gen 3 camera
12 MP, 3K video at 30 fps and 1080p at 60, HDR stills and adjustable stabilisation. It is the best camera a pair of Ray-Ban Meta has ever carried, and the camera is still the number-one reason people buy these glasses: filming the kids, the trip or the ride without pulling out a phone.
The Gen 3 also makes sound. It has open-ear speakers for music, calls and Meta AI's answers. The iO has no speakers at all: everything it tells you, it writes.
Battery: not a close call
The iO lasts up to 48 hours. The Gen 3, 9 hours, plus around 50 more from the charging case.
Two different philosophies. The iO lets you forget the charger for two days; the Gen 3 tops itself up every time you put it away. Day to day the Gen 3 gets to bedtime just fine, but the iO is the one you throw in a weekend bag without the cable.
Weight and comfort
The iO weighs 33 grams — the lightest glasses with a display in our whole catalogue. Meta does not publish the Gen 3's weight, and that counts against it. The Gen 2 weighed 50 grams and the Gen 3 is slimmer, but until they give a figure we are not going to invent one.
Where the Gen 3 clearly wins is choice: three shapes — Wayfarer, Aviator and Zena — and a long list of colours and lenses, including Transitions, polarised and prescription. The iO comes in two colours.
The AI, and the language small print
The Gen 3 runs Meta AI, tied into WhatsApp and Instagram, and Muse arrives this year — the new voice you can call by name.
The iO runs RayNeo AI with Gemini 3.1 Flash Lite out of the box and lets you plug in ChatGPT, Claude or DeepSeek on a separate monthly tier. More open, and more expensive to keep running if you want the big models.
One awkward but important detail: RayNeo's product page confirms English, while several other languages are listed without a firm commitment. Meta confirms its language list outright.
Price, store and warranty
The prices are above. Both are sold today through their maker's own store, not Amazon. And there is a difference almost nobody checks: Meta gives three years of warranty in Europe, RayNeo gives one.
So, which one?
Buy the Gen 3 if you want glasses that record, sound and answer, and you will use them every day to take photos without reaching for your phone. It is the safe pick: confirmed languages, a long warranty and Meta's store behind it.
Buy the iO if your thing is reading: live translation, alerts, navigation, subtitles. And if the camera makes you uncomfortable — yours, or what the person in front of you thinks of it — the iO solves that by design.
Buy neither if what you actually want is real augmented reality. For that you need to look at the RayNeo X3 Pro, with a camera and a colour display, and they cost considerably more.
