Glance up during a meeting and a notification from your phone is right there in crisp green text. Nobody across the table can see it. The RayNeo iO puts captions, translations, a teleprompter and your alerts on the lens, and the most useful of those turns out to be the simplest: checking your phone without touching it.
At 33 grams (1.2 oz), they're barely heavier than regular frames, and from across the room they pass for ordinary glasses. There's no camera, which takes the awkwardness out of wearing them around people.
The display
The binocular MicroLED display is monochrome green, with a 23.5-degree field of view. That's small, but it's plenty for notifications and short text. In a normally lit office, the text is sharp, high-contrast and easy to read, and it stays visible in a bright room. What's on the lens stays private to you.
Comfort
They feel close to normal glasses, but not everyone gets through a long day without noticing them. After about an hour, some heads feel pressure at the top of the nose and around both ears. A nose pad kit comes in the box to relieve pressure, so try the sizes before you give up on them.
Battery
RayNeo rates the 240mAh battery at up to 48 hours of typical use. Running the display or translation nonstop drains it faster. The standard bundle includes a USB-C charging clip, and the case that comes with it doesn't charge. A charging case is an optional extra.
Features and AI
Translation covers 55 languages and 109 accents. You control it with your voice and head gestures, and an array of regular and bone-conduction mics picks up your voice. RayNeo AI and Gemini are free. Other AI models need a monthly VIP subscription.
Setup
You can't set the glasses up without the RayNeo app and a RayNeo account, which is annoying if you just want to put them on. They work with iPhone and Android. Prescription lenses are an add-on, but RayNeo doesn't publish a range. They're IP54, so a light rain shower is fine.
