Eyestrain means different things to different people. It can be experienced as burning, tightness, sharp pains, dull pains, watering, blurring, double vision, headaches, and other sensations, depending on the person. If you have any eye discomfort caused by viewing something, you can call it eyestrain. Things to help reduce eyestrain include:

• Minimize direct glare caused by lighting directly in your line of sight.

• Minimize reflected glare on computer screens.

• Minimize contrast, such as a dark screen surrounded by a bright background like a window or a lit wall. The best solution is to find a way to darken the area around the screen.

• The amount of light you use is going to depend on your age, the quality of the print you're reading, and other factors. There should be plenty of light for easy reading, but too much light can may cause eyestrain. Task lighting, like a a table lamp, may prove to be helpful.
