Like the ones you can find at stores like H&M, ZARA or FOREVER 21, for instance.
I have been told that they are not good for our eyes (aka they might get hurt) because the glass/plastic is far from good quality, and that people should stick to those sold at places where they sell prescription glasses too.
I do not wear sunglasses because I wear prescription glasses and can't be bothered with getting a pair of prescription sunglasses -besides, they would be very expensive since my eyes are 'high maintenance' lol-, but sometimes I just wonder...
I mean, some of those glasses at the stores are pretty darn cute and inexpensive, so I kind of wish they were good enough.
I did get a pair of heart shaped polka dotted red glasses -yeah, ALGO- at Primark for photoshoot purposes, but I would never leave the house with those on anyways, so it doesn't count!
