I have see-through sunglasses, because they are specially made for my eyes. I can’t take them off inside because then i cant see well. But thats exactly why i opted for see-through glasses, so people can still see my eyes. They aren’t hidden :)
I believe that makes a difference to people, they just want to be able to see your eyes :)
Maybe, but you notice how you used the word 'frames' there instead of 'sunglasses'? I bet if they were wearing empty frames they'd have said that, what with those two words meaning different things and all. :P
