Frequent Blinking Helps Prevent Eye-Related Disorders, Optometrist Says

Long hours spent viewing a computer screen may cause eye fatigue and dryness because users often blink less, which can lead to vision-related disorders.

Long hours spent viewing a computer screen may cause eye fatigue and dryness because users often blink less, which can lead to vision-related disorders.

Keshia Sims Elder, assistant professor of optometry at the University of Alabama at Birmingham, suggests blinking frequently while working on the computer to reduce the risk of eye-related disorders.

"Many work in front of a computer all day, and this can leave vision vulnerable to problems like dry eyes, eyestrain, and other problems that may signal computer vision syndrome," said Sims Elder said. "Blinking keeps the front surface of the eye moist."

In addition, Sims Elder suggested other ways to protect sight and avoid computer vision syndrome. Employees should:

Schedule a regular eye examine. Sims Elder said a regular comprehensive eye exam will ensure healthy eyes and correct eyeglass or contact lens strength. "Be certain to tell your optometrist about the computer work you do," Sims Elder said.
Take frequent breaks. Rest your eyes and occasionally look away from the computer for 20 seconds. "Try this quick time-out for your eyes every 20 minutes or so," she said.
Use a humidifier at home or in the workplace. This will boost eye moisture, Sims Elder said.
Wear the right glasses. Eyewear that is specifically designed to function comfortably at the computer can be beneficial. "Special glasses and computer screen filters are available to help reduce glare and discomfort," she said.
