Thanks S2020, I need to look it up more..

Damn, so the most common place is the mall!? Mall has so.., many hotties women shopping around, especially the make-up area..

It's actually better to shop online..

 

My theory about the malls is, besides the effect of AC, the malls are so crowded and often enclosed that the air in there has more amount of carbon dioxide than normal, and it irritates some eyes severely. I can sit in an air-conditioned room and it wouldn't bother me much. But a few minutes inside a mall can irritate the hell out of my eyes - redness, burning sensation, dryness, swelling, etc. That's why I have to avoid malls for many years. I can sit in an AC'ed room without much of a problem, so it doesn't have to do with the AC entirely, but maybe only part of it.
