Eye strain

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.

Symptoms

Eyestrain signs and symptoms include:

Causes

Common causes of eyestrain include:

Computer and digital device use

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 have the greatest risk of this condition.

Computer use strains eyes more than reading print material because people tend to:

In some cases, an underlying eye problem, such as eye muscle imbalance or uncorrected vision, can cause or worsen computer eyestrain.

Some other factors that can make the condition worse include:

Complications

Eyestrain doesn't have serious or long-term consequences, but it can be aggravating and unpleasant. It can make you tired and reduce your ability to concentrate.

Diagnosis

Your eye doctor will ask you questions about factors that might be causing your symptoms. He or she will perform an eye exam, including testing your vision.

Treatment

Generally, treatment for eyestrain consists of making changes in your daily habits or environment. Some people may need treatment for an underlying eye condition.

For some people, wearing glasses that are prescribed for specific activities, such as for computer use or for reading, helps reduce eyestrain. Your doctor may suggest that you take regular eye breaks to help your eyes focus at different distances.

Lifestyle and home remedies

Consider these tips to reduce or prevent eyestrain.

When reading printed materials or doing close work, try to position the light source behind you and direct the light onto your page or task. If you're reading at a desk, use a shaded light positioned in front of you. The shade will keep light from shining directly into your eyes.

Your doctor can suggest which eyedrops might be best for you. Lubricating drops that don't contain preservatives can be used as often as you need. If the drops you're using contain preservatives, don't use them more than four times a day. Avoid eyedrops with a redness remover, as these may worsen dry eye symptoms.

Tips for computer work

Computer use is a common cause of eyestrain. If you work at a desk and use a computer, these self-care steps can help take some of the strain off your eyes.

If you need light for writing or reading, use an adjustable desk lamp. Close blinds or shades, and avoid placing your monitor directly in front of a window or white wall. Place an anti-glare cover over the screen.
