Arggg, itchy itchy eyes!!

Since last Sunday, the minute I woke up, my eyes were very itchy. I'm not sure why but it's just soooo itchy. I forced myself not to go touch my eyes and keep washing it with Optrex.

When I woke up on Monday morning, i got an itchy and red right eye. Washing with Optrex does makes me feels comfortable a bit but it still very itchy. Even until today, I'm still having itchy eyes!! I'm not sure what causing it, is it because of the air? or is it because I spent too long time in front of the computer? or is it because I don't have enough sleep?

Arggggg... It's so irritating!! please go away...
