Prevent headaches from working at the computer
Do not work continuously on your computer for more than half an hour. This in fact is a very relative concept because some people tire faster than other when working on the computer. Computer screens emit radiation, so the less time in front of the computer, the better. Or switch to one of the newer, flat plasma screens which are much easier on the eyes.
If you feel that your eyes are under strain, take a break. The best relaxation for your eyes is staring at a distant object or just keeping them closed. Your eyes will give you signs when they are under strain. You will find that you are getting tired sooner, your eyes may start to water or you might notice that you have to squint your eyes in order to get a better view.
If your eyes give you signs that it has had enough take the cue. But often, after you get used to working on the computer, you start ignoring these signs. The best thing you can do is make it a point to give your eyes a break at least every half hour of working on the computer.
The best rest that you can give your eyes is staring at a distant object.
Use an anti-glare screen to cut out the radiation while working on your computer. Radiation is bad for your eyes and an anti-glare screen is the only and the best solution to this. Another option is to wear glasses that have an anti-glare coating on the lenses.
Try to blink deliberately while working on the computer. When you work on the computer there is an increased tendency to stare unblinkingly at the monitor. This especially true if you are playing an exciting game. In such cases you should make a conscious effort to blink your eyes.
If you do not blink your eyes, they will become dry, they will hurt and this will ultimately precipitate as a headache. It is when you blink that your eyelids wash your eyeballs with the tear secretions. Your eyeballs must be moist always so remember to blink your eyes even if you are deeply engrossed in something interesting.
The room where your computer is should be properly lit. Watching television or working on the computer in the dark unnecessarily strains your eyes. Make sure to always turn on a lamp or overhead light.
In the ideal condition, the light source should be behind you placed in such a way that the glare des not reflect on the screen.
If your job requires long hours in front of the computer, you may want to consider buying a special lamp that clips on the monitor. This lamp reduces the eye-strain caused by staring at the computer screen, and thus reduces headaches.
