I've worn them for ~ 50 years, Sam.
I wouldn't be without them.
Like many blue-eyed folks, I'm very light sensitive, though.
I also found I need dark sunglasses on very bright, or snowy days. Particularly driving, the transitions don't darken as much as normal.

I've always been a curmudgeon - now I'm an old curmudgeon.
