Reducing Near-Point Stress on the Eyes Headaches, burning and watery eyes, squinting and eyes that tire easily are common symptoms of near-point stress caused by such continuous close-up visual activities as reading and writing. The problem lies in the fact that human beings were not designed for near vision as a continuous activity. We have "hunter-soldier" eyes for survival. Only in the last 50 years or so have so many people been forced to deal with sustained, near visual tasks. Many visual difficulties can be reduced by following a few of the following simple guidelines:
Look up and away from your close-up task regularly. Make it a habit to change your focus from near to distant objects as frequently as possible.
When watching television, try to sit eight to ten feet away from the set. The ideal distance for close up visual tasks is 14 to 16 inches from the eyes
Good lighting is important. A good rule of thumb is to make your working or reading light three times brighter than the lighting in the rest of the room..
