Question

Why do peoples eyes look puffy or tired when they take off their glasses?

Answer 1

You know I've never actually noticed that but a friend of mine would wear her glasses rather than contacts if she thought she had dark circles under her eyes because she said the frames hid them!

Answer 2

Maybe they are aliens!  

Answer 3

mine do too. i think its because you/we/I aren't used to looking at the person without glasses on or something to do with that..

Answer 4

I think because many of us choose our frames to conceal that puffiness, and tiredness... so it really jumps out  when we take our specs off.
