Eyestrain Eyestrain occurs when your eyes get tired from intense use, such as driving a car for extended periods, reading or working at a computer. Although eyestrain can be annoying, it usually isn't serious and goes away once you rest your eyes. In some cases, signs and symptoms of eyestrain can indicate an underlying eye condition that needs treatment. Although you may not be able to change the nature of your job or all the factors that can cause eyestrain, you can take steps to reduce eyestrain.

How to Reduce Eye Strain How to reduce eye strain: What is the best reading posture for comfortable reading? The best light is daylight. The human eye has been "tuned" to daylight. All other sources of light are really poor substitutes. The ideal reading position would be a sitting posture with the head erect; the book being kept, if the reader is below the age of 35, sixteen inches away, if above the age of 40, at the focal length of the reading glasses prescribed. The light, be it daylight or artificial light, should come from the left, preferably over the shoulder, to prevent glare. It has been noticed time and again that if the eye is permitted to relax by looking at the distance intermittently during reading, eye strain does not develop despite long hours of near application. Thus, every effort should be made to be near a window, where one can occasionally glance out to relax the accommodation. Eye strain also tends to develop faster if the eyes are pushed to read for long periods when they are tired.
