Meta CEO Mark Zuckerberg showed off a flurry of new AI and mixed reality products, including a future version of holographic glasses, at the company's annual Connect developer conference on Wednesday,

Perhaps the most interesting feature of the Orion glasses are the lenses, which are not made from glass or plastic. Instead, Meta is using a silicon carbide where tiny projections are beamed onto the lenses. This material is supposed to be more durable, lighter and features an ultrahigh index for refraction of the on-board projectors.
