Eyestrain is a common condition that occurs when your eyes get tired from intense use, such as while driving long distances or staring at computer screens and other digital devices.
Eyestrain can be annoying. But it usually isn't serious and goes away once you rest your eyes or take other steps to reduce your eye discomfort. In some cases, signs and symptoms of eyestrain can indicate an underlying eye condition that needs treatment.
Extended use of computers and other digital devices is one of the most common causes of eyestrain. The American Optometric Association calls this computer vision syndrome or digital eyestrain. People who look at screens two or more hours in a row every day are at greatest risk of this condition.
In some cases, an underlying eye problem, such as eye muscle imbalance or uncorrected vision, can cause or worsen computer eyestrain.
