The Meta Ray-Ban Display’s most interesting tech might be the glass

The Meta Ray-Ban Display glasses feature advanced glass technology that sets them apart from other augmented reality (AR) glasses. According to the iFixit teardown, the glasses use a reflective geometric waveguide system in the lenses, which bounces light to the wearer's eyes at specific angles, preventing others from seeing the screen. This system differs from the older "diffractive" approach used in other AR glasses, which can cause visual artifacts for the user. The glasses also include a liquid crystal on silicon (LCoS) micro-projector in the right arm that generates a 600x600-pixel grid image. While the glass technology is impressive, iFixit notes that the manufacturing process is likely expensive, suggesting that Meta may be selling the glasses at a loss. Additionally, the teardown reveals that the glasses are not designed for easy repairs, as the arms and frame need to be split in half, and Meta did not provide a way to clip them back together. iFixit concludes that any repairs will require specialized skills and tools, indicating that the first iteration of these smartglasses is not user-repairable.
