Having to buy prescription sunglasses is so annoying - they're expensive up-front, and then they need re-lensing as your eyes change, instead of just being something you can keep. I'm currently in a dispute with a company who sent a pair back with a bent frame *and* a chip on a lens.

Have also chosen a new pair for a different style - and explicitly ruled out Ray-Ban because I don't want to be associated with those weird Meta glasses!
