Yes some exercises like blinking your eyes rapidly is supposed to help.I guess the best thing to do would be to take a break after every hour and do some thing else , which is good both for your eyes and body which receives some much needed exercise..

I had a long break of two hours today but could not stand it any more. So I am back to business. I will try it later again.

It's not possible to take long break always at that time just try to blink your eye and wash them after 2 to 3 hours. This was suggested by doctor to me. Ya also don't forget proper posture is must.

Yes washing eyes with clean water is supposed to be very good.I normally take a break after an hour or so and get busy with something else .That way I dont neglect my other duties and also taking care of my eyes ..

Yes due to this we may cause cancer also this is discussed here previously.

Which cancer we may have by this Sasi? :blink:

I was told that it is also very important to have sufficient light since many people use the computer even in the dark managing with just the light on the screen which is not good for our eyes...

Most people have this habit of watching TV too with no lights on in the room.They want to get the theater experience while watching a film at home I guess ! :) But, one can feel the strain on our eyes , I have had this experience once while watching Tv at a relatives house..the same goes for computer, many people do the same..

Most people these days spend long hours in front of the Computer or watching TV. We all know that both these activities are bad for our eyes and health too since it curtails physical activity.Most of us would agree with that since we all have personal experience of using both ...However , it is better to be careful while you can rather than regret later…I have a relative who is unable to use his fingers since they shake – the doctors say that the nerves are swollen and it is because of using the computer.He used to use it for 10 -12 hours a day for something like 11 years..
