Overview
- The lenses use a reflective geometric waveguide, supplied by specialty glass makers such as Schott using Lumus-developed tech, to direct light to the wearer and limit onlooker visibility.
- A right-arm liquid crystal on silicon micro‑projector produces a 600×600‑pixel image that avoids rainbow artifacts and the telltale eye glow associated with diffractive waveguides.
- iFixit says common fixes would require splitting the glued arms and frame, with speakers soldered in and bespoke lenses difficult to source, leading it to deem the first model effectively unrepairable.
- Hackaday notes a roughly 960 mWh internal battery accessible only after heating and prying open the arm, with spare parts beyond the battery likely hard to obtain.
- The glasses sell for about $800 in the U.S., and iFixit speculates the specialized optics raise manufacturing costs enough that Meta may be selling at a loss.
