Discover the Cutting-Edge Waveguide Technology Powering Meta’s Ray-Ban Smart Glasses

Recently, the teardown experts at iFixit took a close look at Meta’s Ray-Ban Display glasses. They uncovered some exciting technology: a geometric waveguide that enhances the floating display feature. For those who enjoy gadget disassemblies, iFixit also released a video showcasing the entire teardown process.

These smart glasses show some promise when it comes to repairability. You can open the arms with a bit of heat, revealing a 960 mWh battery and several printed circuit boards (PCBs). However, finding spare parts may be tricky beyond the battery.

The front of the glasses houses an antenna and a special lens that works with a liquid crystal on silicon (LCoS) projector. This projector reflects images directly to your eye. Although LCoS is not new—having been used in devices like Google Glass—the innovative waveguide technology in these glasses stands out. Instead of the usual diffractive waveguide, Meta uses a geometric reflective waveguide, developed by Lumus and manufactured by Schott. This upgrade promises improved optical efficiency and reduced light leakage.

Despite these advancements, the glasses aren’t highly repairable. Plus, there’s the style factor; some people may see wearing them as a bit “dorky.”

Tech expert Jane Doe notes that while these glasses are a step forward in augmented reality (AR), the balance between functionality and fashion remains challenging. As AR technology evolves, wearable designs must become more appealing to gain mainstream acceptance.

Interestingly, a recent survey found that 64% of potential users cite style as a primary concern when considering smart glasses. This finding highlights the ongoing tug-of-war between innovation and user perception.

In conclusion, while Meta’s Ray-Ban Display glasses showcase impressive technology, their practicality and aesthetic appeal may hold them back from widespread adoption. For further details on this technology, check out reports from Lumus and Schott.
