why do people wear dark sunglasses inside buildings or at night??.. these are not blind people. do they......?

There could be some others reasons except for being look cool. The Hong Kong director Wong Kai Wai wears sunglasses everywhere, at first I thought he just wants to look cool but later I found out that he has some eye disease and his eyes would get hurt if he sees lights.

Some may be light sensitive. Most think that they look cool.

no , their not blind... they just wanna show there new gucci or dior sunglasses , wanna look cool and act cool...or maybe they just forgot to take there sunglasses off..

They probably have something wrong... I had caught that eye fungus and was treated for 2 years and I could not see in the light, it's light sensitivity and I had to wear sunglasses in the house and in stores, everywhere, light is very painful, it was awful and very embarrassing, people judge and make fun before they know what's going on....

I have some custom made chanel sunglasses that get really light inside and then when you go outside they turn really dark, and i do look good.

There are some people in the world who are immature and think that wearing sunglasses indoors or at night are cool. Actually it is if you see them wearing but if you think of it, it is actually quite dumb. So my advice is stop noticing all the nonsense people are doing in the world as that will just make you stress and think more. It will give you more wrinkles over the years.

Yes I think that's why most of em do it. Some people who wear them in buildings may have other reasons.....like they're extra-sensitive to light....or they had a heavy nite...

My answer to this would be that either they forgot to take them off, or they are hiding their bloodshot eyes, or they just think they look cool and don't care how hard it is for them to see where they are going.

Yes and No. The sunglasses are obviously part of their own self image and they are more comfortable with them on.

I don't see the cool factor, but I like to wear shades in the evening, I've always been weird like that!
