Do smart glasses really translate conversations? (2026)
Where it stands
As of Oct 22, 2026: live translation in the lens is on sale in the Meta Ray-Ban Display ($799). Reviewers found it useful but imperfect.
Real-time translation is the feature people most often ask smart glasses for. Here's what two long reviews of the Meta Ray-Ban Display found.
How does it work?
The glasses listen to the person in front of you and show their words as text in a small display in the right lens, either as captions or translated. You control it with a wristband that reads finger gestures.

How good is the translation?
Useful, not perfect. Engadget's reviewer talked with a native Spanish speaker and found it more natural than audio translation, but it still missed some of what he said. Tom's Guide tested it on an Italian TV series: adequate, but it dropped fast dialogue and garbled some lines.

Which languages?
At the time of Tom's Guide's review: English, Spanish, French and Italian. Check Meta's current list before buying, since features have changed with updates.

What does it cost in battery and comfort?
Meta quotes about six hours, but Engadget says display-heavy tasks like live translation drain the battery much faster. The frames are thick and weigh 69 g, with pressure after six or seven hours.

Is it a privacy problem?
Engadget points out that live translation could be used to quietly listen in on conversations you otherwise couldn't follow, which is also true of Meta's other glasses. An LED lights up when the camera records.

How we know (2 sources)
Ten days with the $800 Meta Ray-Ban Display: a bright display in the right lens for messages, Meta AI, walking directions, camera preview and live captions and translation. Translation in a real conversation was smoother than on display-free glasses but missed some words. Frames are thick and 69 g; battery runs about six hours and drains much faster with translation or video calls. Few apps so far.
Read the sourceReview (updated Jan 31, 2026): the most complete smart glasses the reviewer has tested, but expensive, with limited third-party apps and half-baked maps. Live captions appear within a second or two; live translation (English, Spanish, French, Italian at the time) was adequate but missed fast dialogue. Battery drained faster than Meta's six-hour figure.
