I couldn't find 0.75 glass anywhere. I took a risk especially with the size, but it's just fine for a man in terms of size. For the minimal use I make of them, they are just right.

From the first day, the lens would come out of the frame... eventually, at some point while I was wearing them, the frame broke on its own where it circles the lens at the top... I had bought 2 pairs, the same thing happened to both

As other users have said, they have a fragile frame. I ordered 2 pieces, one arrived broken on both sides! Fortunately, the store replaced it for me immediately.

I bought two pairs which both broke (both of them) within two months.
Very fragile frame that breaks easily.

Decent glasses for their price, nice design, they are not different from prescription ones, upon order. Good for anyone who wants to have multiple pairs at home and anywhere, without worrying about high charges...
