How much hours should i stay on a computer/laptop ?

Depends on what you are doing. If you are studying, then GOOD JOB! Keep at it. But if you are just wasting time on a site such as Facebook, then maybe you should cut down on time...
Thats a little too long you can have some serious eye problems when you get up in your age
i spend 3 hours on mine !
The best 2 to 3 hours, don't long time sitting on the side of computer, affect vision and body health.
