Computer users don't get tired as others why??

Most probably because of the fulfillment (or part of it) that we get because of computer usage. Most of our daily activities revolve around it now so it is slowly becoming a part of our system. The downside though is that it will hurt your eyes. Yikes!

I use computer 8~12 hours a day. My eye is dry after a day's work. Perhaps many workers have such experience. Firstly, there is no way to eliminate eye fatigue, our eye strain problems would be worse. Uncorrected farsightedness may contribute to eye fatigue. Dry eyes can also make the eyes feel more tired when doing extended computer work.

there are so many information and interested things on the Internet, people can read news, watch movies,play games,and chat with friends, they are enjoying what they are doing, so they feel time goes so fast and not feel tired. on the other hand, people always sit before computer without moving, they feel comfortable.

Hi dear, Self interest and involvement is the main reason. Also, in computers, it is just like a flow and whatever we do on computer is like reading a novel. As and when we work more the involvement and mental insertion is too much involved. Sometimes, we never bother what is happening near by. The more we concentrated on work, the participation of mind also become more specific and mind works. Again, to a certain extent, thinking also involved. The more time we use, simultaneously our mind works and the thinking passes through fingers and key board, eyes are concentrated on screen or monitor. Means our sense organs mostly inter bonneted with the device and this cyclical process continues for a long time. Again, some works are mostly based on result oriented and time bound things, most people would prefer to work at one stretch and more closely related interaction with computers. This would result interesting and most of the time we wont feel tiered or boring. Especially, the work choice is ours and we enjoy the same also. Thank-s

Maybe because when you enjoy what you are doing, there's a tendency that you lose track of time, and before you know it you've already spent a lot of time in the computer than you should have. It actually happens to me most of the time.
