iO

The iO solves the problem almost nobody else has solved: display glasses you can wear all day without thinking about them. At 33 grams they are the lightest with a display in our catalogue, and up to two days of battery takes the nightly charger out of your routine. The display is a monochrome green waveguide: sharp for notifications, navigation and captions, and deliberately incapable of playing video — that is not its job.

Its best feature is translation: some 55 languages at roughly one second of latency, enough to follow a real conversation. The missing camera cuts both ways, and we count it as a win: nobody around you has to wonder whether they are being recorded — but there are no photos either. There are no speakers at all, so audio goes through your earphones, and the third-party AI models sit behind a separate monthly subscription.

Who is it for? Anyone who wants a discreet everyday HUD — agenda, messages, translation — while still wearing something that looks like normal glasses. If you expect a camera and media, you are in the wrong category: Ray-Ban Meta does that better, and we compare it with the iO head to head. And if what you want is cinema, look at RayNeo's own viewers instead.
