Eyestrain from reading or using computers doesn't really injure the eyes, but it makes them tired. To be exact, it is the muscles around the eyes that get tired or strained. The best cure for eyestrain is to give your eye muscles a rest. Take a break from what you're doing. Close your eyes for a while, or stare off into the distance for a moment.

Also, you may want to use a desk lamp while reading or sewing, but make sure it doesn't shine into your eyes. Remember, the finer the task, the more light required.

Eyestrain can cause discomfort, such as watery or dry eyes, difficulty focusing, fatigue, and perhaps headache. Also, although eyestrain itself isn't serious, it can be one symptom of serious conditions, such as glaucoma. If you're bothered by long-lasting, frequently recurring eyestrain, you should see an eye-care professional.
