Your optician will also encourage you to wear sunglasses year-round, UV damage can occur even in overcast conditions.

I see an independent optician who is fairly old. Although they sell sunglasses, the optician has never suggested that I should wear them. Do you think this is perhaps newer guidance that is shared by more recently-graduated opticians, or maybe something promoted by a major chain of opticians?

I'm of the older generation (in my 50s), and at least in my circles, Ray-Bans aren't particularly cool either. They're not exactly un-cool, but they do tend to be worn by a particular sort of person.

Apple? Or do you mean Meta? It would be understandable if you had never heard of them, given the recent rebrand!
