why do most people wear sunglass in the night time or inside

I dont know either. But it has always been my instinct to take off my glasses when I already under a roof. Maybe some people do that as a fashion statement. They think that look cool even if they look stupid.

there are many reasons why people wear sunglasses during the night or inside.one reason is that people who are shy are not always comfortable staring into another persons eyes or anything that has to do with crowd,but instead of looking down,they rather put on sun glasses.another reason is that pompous people wear it to feel on top of the world and when such speak...u detect pride in their voice.then some people wear it because of their eye problem or "photophobia".may be they cant stare directly at a bulb or anything that generates light. it once happened to me when i had an accident. I had photophobia,that when i sleep and i wake up...its a problem any time any day. Remember, not everyone thinks like you, some people might just be obsessed with sun glasses.

People do this for many reasons. Some because they like to stare and don't want people to see who they are starring at. Some because they have red eyes for one reason or another. And some people are just insecure and they feel like if you can't see their eyes you can't see them. Or can't see what they are thinking or how they are feeling. Eyes can tell a lot.

It makes them look cool I guess or maybe they don't want their eyes to be seen.
