E1O guides / Field guide
Smart glasses without a camera
A camera-free frame can still have microphones, a display and a cloud connection. Here is how to separate those choices before choosing a pair.
A display. A different point of view.Start with what you want the glasses to do. Reading a short message requires a display. Listening to a spoken answer requires audio output. Photographing the scene in front of you requires a camera. Those are separate capabilities, and the label “smart glasses” does not tell you which ones a particular model includes.
This guide is written by E1O, which is developing camera-free glasses. It explains the distinction using manufacturer information and our current product direction. It is not a hands-on comparison of shipping hardware.
Three questions to ask separately
Is there a camera on the frame?
Check the exact model, not just the brand. A camera-free frame cannot photograph its surroundings using an onboard camera. That does not tell you whether the companion phone app can request access to the phone’s camera. Even’s developer documentation, for example, lists no camera on G2 while explaining that a plugin can access the phone camera with permission.
Can the glasses capture audio?
Microphones support spoken requests and other audio features. Their presence, controls and processing deserve a separate check. Even G2 has a microphone array despite having no frame camera. Ask how to disable capture and whether the feature you want needs the microphones to stay available.
Where does processing happen?
The glasses, phone and online services may each handle different parts of a request. Camera-free hardware does not establish offline operation or a particular data-retention policy. Read the documentation for the specific feature and service you intend to connect. Even’s hardware and phone architecture documentation illustrates these distinctions.
Examples, with the differences kept visible
| Product | Camera on the frame | What to check next |
|---|---|---|
| Even G2 | No, according to Even. | It has a display and microphones, and uses a companion phone. Confirm feature availability and data handling. |
| E1O | Camera-free product direction. | In development, with a private display and a connected phone. Final hardware specifications and availability are not announced here. |
| Ray-Ban Meta Gen 2 | Yes: the manufacturer lists a 12 MP camera. | This is a camera-equipped example. It does not satisfy a requirement for a frame without a camera. |
Sources checked September 8, 2026: Even G2, E1O’s YC profile, and Ray-Ban Meta product information. Product generations matter; this table does not describe every model sold by those brands.
Choose around a real task
For a teleprompter, check whether you can comfortably read your script, advance it and resume your place. For short notifications, check how much text is visible and how you dismiss it. For translation, distinguish written translation on the display from spoken translation through audio. For coding-agent updates, find out where the agent continues running when you walk away from the computer.
A useful demonstration should show the actual device, a real input and its result. A display illustration can explain layout, but it cannot establish outdoor brightness, optical clarity, battery endurance or how the frame fits your face. Ask for those observations separately, especially before buying a product you have not tried.
Where E1O fits
We are building camera-free glasses for useful information in your line of sight, connected to a personal assistant through the E1O phone app. Coding agents remain on an awake, connected Mac. Our website’s display previews use firmware layouts with example content; the illustrated scenes and product concept renders are not physical optical tests.
If that matches your use case, join the early-access waitlist and tell us what you want to do. We have not announced a public launch date, and joining does not guarantee an invitation.
