Over 80% of Sunscreen Performed Below Their Labelled Efficacy

I know ultraviolet CCD sensors exist and are probably expensive, specialty scientific equipment. I've kinda had this hope that one smartphone manufacturer (any of the big ones) would go to the trouble of including a UV camera and drive costs down. On the one hand you can market a unique and fun photography tool that lets you see the world in a different way. And then in the more serious part of the commercial, you show friends at the beach taking UV pictures of each other after applying sunscreen and one person says "You missed a spot right there, mate."

Plus I'd imagine you could immediately tell if your sunblock were BS and do an even better job of holding these folks accountable. You and buddy of similar skin tone both buy SPF 50 and apply it, take pictures, and see that one of you is not as well protected.

I've wanted this!

Also, cheap chinese UV camera tablets ($25) that just showed you yourself through a UV camera. This seems more likely to happen than getting Apple to add a UV camera. They already sell cheap LCD photo frames. I'm sure they can make them cheap. A few influencers and suddenly everyone would get one for checking their UV protection.

Camera sensors are already sensitive to UV, and in fact, have a UV filter that, if you remove it, will let any camera see UV.
