Eyestrain occurs when the eyes become tired from being intensely used for a long period of time. Activities that often cause eyestrain include reading for a long period of time or trying to see in dim lighting. Computer eyestrain is very common, as many people work all day with their eyes focused on a monitor. The symptoms of eyestrain include discomfort, watery or dry eyes, itchy or scratchy eyes, blurring, difficulty focusing, fatigue, headaches, and sometimes doubling vision. Although the symptoms of eyestrain are bothersome, they usually pass after resting the eyes. Although eyestrain itself is not serious, it can be a symptom of a serious condition, such as glaucoma.
Reducing eyestrain is simple. When reading, make sure there is adequate light in the room, and be sure to look away and focus on something else in the room every couple of pages. When working on the computer, reduce both outdoor and indoor light. Be sure to minimize glare off of walls or off the computer monitor, use an LCD monitor, and adjust your monitor’s brightness and contrast so it is about the same brightness of your office.
Experts also say that blinking more often, taking short breaks throughout the day, closing your eyes for a few minutes, and exercising your eyes helps reduce eyestrain. A good eye exercise is to focus on an up-close object for 10 to 15 seconds, and then focus on a faraway object for the same amount of time — experts say to repeat this exercise 10 times.
