I have to say that I buy what I can get at the dollar store. So far I have found two pairs that fit good keep gunk out of my eyes and are fully functional one super dark lens and one yellow lens. Good glasses in my opinion. Like Irulan I too have been known to forget them on bumpers sit on them ect. (or worse for some) let my grandson play with them. I can pay good hard earned money on bikes, bike clothing, and parts for the bike but not for sunglasses.
