Your eyes contain many tiny muscles. Their main job is to change the shape of the eyes. Your eyes actually change shape so they can focus and move up, down, and side to side. Your eye muscles function the same as all your other muscles in the body, if they do not get the proper needed exercise your muscles can weaken, especially as we age. Most people have to wear glasses / lenses because their muscles are too weak and therefore cannopt chance the shape of their eyes.
Aging actually causes the lens of the eye to harden and so force the muscles to work harder. You can learn how to exercise and train your eye muscles. You can improve your eyesight with these eye exercises.
Most eye problems come from either emotional / mental stress or near point stress. You should learn to relax the eye and the eye muscles. Relaxing your eyes sounds difficult, but it is much easier than you think.
Practice palming, this procedure really helps relax your eyes. Also, practice looking away... Every 10-20 minutes that you stare at your screen, look away for 10 seconds at an object at least 10 feet away, preferably, something nice to look at, like a natural view :)
