do you feel headache some times when you do work on your computer?

Yes sometimes, but I always feel my eyes are hurting when I used computer more than 4 hours. Tears comes out in my eyes. I feel sick and over used. Stressed out and very tired. I read some discussions here in my lot and I responded. They advised me to have as break time to time.

Yes,i am also feel headache when i am working before the computer for long time.I think almost every one will have this feelings,especially when the workload is very heavy,we have to make extra work on computer,and at this time,my headache will sharpen.So i always listen to my favourite music and do some meaningful things to lighten my pain.

yea,nine times out of ten it's the brightness of the monitor that gives you the headaches.i've found i can work a lot longer just by turning down the brightness.

Yeah, I feel that sometimes. But whenever I feel that way, I try to stop and rest my eyes for a while, it helps.

I do not feel headache while working with my PC, i work about 10 hours daily with my computer. If i feel bored browse through various endangerment sites or watch movie clips.

yes many a times when i work for hours i fell headache , actually it felt even today since i was working for 4 hrs continuously in front of computer screen so my head was bursting in pain , so i went to the nearby park for some time and the headache disappeared.and the above suggestion is truly correct about the luminisens, of th computer screen . well i also turned it down , and it is really feeling good to my eyes.
