I’ve always thought smart glasses makers should explore updating prescriptions as eye sights change so people didn’t need to buy new lenses. Is it possible? I’m surprised no one (I’ve seen) has introduced this. Disposable tech is not good for the environment.
Heading to San Fran (as the locals call it). What local-hole-in-the-walls (other than California Pizza Kitchen and Philz Coffee) should I be sure to check out?
