I was sitting at my computer today and then started having problems focusing. I noticed that my eyes started to go up and down cross eyed (room was stacked). If I looked down it wasn't as bad as well as with my peripheral vision. I have been on my computer for about 5 hours today and 5 hours last night (I'm a graphic designer...I'm almost always on my computer). Could this be a result of computer eye strain? Both monitors are LCD but at work I have fluorescent lighting. I intend to see a doctor because it's not normal for me (first time this happened) but he's not in today.

Also..no symptoms like nausea or faintness or dizziness. It was just really weird. I also had dilated pupils.
