But what are AI glasses actually for?
A camera, speakers and an assistant that answers out loud. What these glasses really do, what they do not, and the two questions to ask before spending.

They look like ordinary sunglasses from a brand you know. Inside the frame, though, are a camera, microphones, two speakers hidden in the arms and an AI assistant you talk to out loud. They start at a few hundred euros, about the price of a mid-range phone, and you can buy them in a shop.
That this is interesting technology, I am not arguing with. What remains to be worked out is whether an ordinary person needs it.
Smart glasses: glasses with electronics inside, usually a camera, microphones and speakers. AI assistant: the program you talk to and that answers out loud, like your phone's but more capable. Open-ear audio: speakers that play near your ear without blocking it, so you still hear the world around you. Display: here it is not a full screen in front of your eyes, but a small panel appearing in one corner of your vision.
Two different categories, worth not confusing
What you can mostly buy today is the first category, glasses with no screen. They have a camera, speakers and a voice assistant. You see nothing, you hear. These are the Ray-Ban and Oakley models made with Meta, and they start at a few hundred euros.
The second category has a lit panel inside the lens, showing messages and directions. That is the one the newspapers write about, and in much of Europe it is also the one you cannot buy. The most talked-about model is on sale only in the United States, and its European launch, announced for early 2026, was postponed by the maker with no new date. If you read an enthusiastic piece about glasses that show walking directions in front of your eyes, it was almost certainly about a product you cannot have yet.
So the rest of this article is mostly about the first category, the one you could actually buy.
What they really do
They take photos and video without you pulling out your phone. Press a button on the arm, or ask out loud, and the photo is taken. This is the feature people use most, and it says plainly who they suit: anyone whose hands are busy. Cooking, cycling, carrying a small child, working with tools in hand. Image quality is below a good phone, but in those moments the phone is in a pocket.
They play music and handle calls without blocking your ears. Anyone walking through a city, or running, really does appreciate still hearing the traffic.
They answer questions about what you are looking at. Ask “what is this monument”, “read me this label”, “do these two colours work together”, and the assistant answers out loud. It is the part that impresses in demonstrations. In daily use it helps in flashes, and the reason needs saying: the answers are sometimes right and sometimes wrong with equal confidence, and you have no way of telling at that moment.
They translate a live conversation, but only between a handful of languages, which have to be downloaded first. If you were hoping for the universal translator from films, we are a long way off.
Where they genuinely help, and who for
The strongest case is someone whose hands are busy and who wants to record: a craftsperson filming a job, a motorcyclist or cyclist, a parent who does not want to spend the day behind a screen. The second is anyone who wants music and calls with ears free, and would have bought glasses of that brand anyway.
The weakest case is curiosity about the assistant. In my view, if you buy them for the AI, after three weeks you will be using them for music.
Then there is one use that deserves a line of its own and gets talked about very little. For people with very little sight, being able to have what is in front of you described out loud, and a label read to you, is a serious matter rather than a toy. Anyone in that situation should try them before buying, though, because performance varies a lot with light and with the kind of text.
You do not "see the internet" inside your eyes, and nothing is overlaid on your vision with the models widely on sale. They are ordinary glasses that hear and speak. If what worried you was the idea of images projected into your eyes all day, that is not what happens.
Two things enthusiasts leave out
The first is the battery. The stated figures run to several hours, and they hold if you use them as glasses with a bit of music. If instead you do what you will want to do in the first weeks, filming and asking the assistant things constantly, the battery collapses, and people who have used them that way report far shorter run times, on the order of an hour or two. Before trusting the figure on the box, look for a recent review of the exact model you are considering. The case recharges them several times, but it needs charging too.
The second is that the camera points at other people. It is the most delicate part of the whole business, and it deserves the section below.
The camera-in-other-people’s-faces question
There is a small light on the frame that comes on when you record. It is there to warn the person in front of you. The problem, raised by European data protection authorities that have examined these products, is that the light is hard to see outdoors in bright light, which is exactly where sunglasses get used.
And there is a consequence buyers often do not have in mind: when you film other people, you are the one responsible in the eyes of the law. European data protection rules do not reach into what genuinely stays inside your private life, but that exemption falls away when you film strangers in public and above all when you publish those images. Filming a party at home and filming the queue at the post office are two different things legally.
Nobody is fined for wearing glasses. But a few habits avoid nearly every problem: saying out loud that you are recording when others are in shot, not filming where people expect not to be filmed (changing rooms, clinics, schools, crowded transport), and not publishing recognisable faces of strangers without their agreement.
What leaves your glasses
To work, the assistant sends what you ask to the maker’s servers, so it needs a connection and an account. Photos and videos stay on your phone until you share them. But when you ask a question about an image, that image is sent and stored, and is generally also used to improve the systems. The same goes for voice recordings.
Options to limit that storage exist, but they vary by country and over time: look at them in the app settings on the day you switch the glasses on, not on the box. And then a practical rule that always holds, do not ask the assistant to read personal documents, medical results, payslips or identity papers.
If you would buy glasses of that brand anyway and you like the idea of taking photos and listening to music without pulling out your phone, they are a fine object and you will use them. If you are weighing them up for the artificial intelligence, wait. Today the assistant is the least mature part of the product, and the one that promises most is on models not on sale across much of Europe yet. Look at what they do now, in the shop, and decide on that.
One thing to try first
If you can, wear them in the shop for a few minutes. They are heavier than ordinary glasses and not everyone finds them comfortable after a few hours. If you wear prescription glasses they can be fitted with corrective lenses, but the cost of the lenses is on top of the frame and your optician has to quote it, because it depends on your prescription and the type of lens.
If the idea of an AI that answers out loud interests you more than the object itself, try the one already in your pocket before spending: I cover it in what actually differs between ChatGPT, Gemini and Copilot.
