Avoid eyestrain
The image you see on your computer screen is not a natural image, and after staring at a computer screen for a long time, you may get eyestrain, headaches and visual disturbance. To help your eyes every 15 minutes, lift your eyes from the screen and look at a distant object – out the window, down the hall, or the farthest object you can find. A dark green object is the best to look at. Gazing at a distant object, the eye muscles can relax, because they do not have to pull the eyes into focus, where both pupils sare oriented towards the center.
Watch Your Back
As we are in a position almost exactly the same for maybe hours at a time, that position should be correct if we are to avoid straining our backs. If bent or sitting in a way where back muscles area straining to keep us in place, it will lead to back discomfort or cramps knots. Make sure your chair supports your back, and try to sit as straight as possible without being tight or uncomfortable. If your chair is not comfortable, try to swing around in your seat and get up and stretch every so often to relax your muscles.
Avoid repetitive strain disorder (RSD)
Holding the mouse in the same manner for long periods can cause a condition known as repetitive strain disorder in a joint such as the wrist. This can cause it to be damaged by tension over a long period of time. This damage can be quite painful and difficult to correct if left untreated. To prevent this problem, take your hand off the mouse and put it under the table and pull upward with the palm of your hand, then press down on the table with your fingers. Then flex your fingers quickly, and then move your hand up and down and sideways, bending the wrist - in other words, all moves that are different from the movements you make with the mouse. Above all, do these movements, if the mouse hand starts to feel stiff or sore, and even more, especially when it comes to the wrist.
Avoid a stiff neck
To avoid a stiff neck, make sure the computer screen is angled correctly so that the surface of the screen is 90 degrees to the line of sight. Also, organize your desk, chair, screen and the screen at a height that is most comfortable for your neck muscles. Looking a bit down on the screen is usually the best because it relaxes the neck, but experiment a bit until you find the height of the screen more comfortable for the neck muscles.
Use the Right Equipment
Make sure your screen has good focus and resolution. Blurred images can cause you to ruin your eyes and you will be unable to concentrate, resulting in fatigue. Keyboards are cheap, so find one that is easy to use, without having to use excessive force, and find one with a design that is comfortable for you. Do not use a mouse that is too small or too large for your hand, but find one that "fits" you and is always comfortable.
This advice may seem trivial, but following it can prevent serious damage to our body. These things are easy to follow, and ensure that we will continue to enjoy our computers for a long time to come.
