Washington, Mar 11 (ANI): Blinking frequently while sitting in front of the computer helps reduce the risk of dry eyes from prolonged use, say researchers.

Keshia Sims Elder, assistant professor in the University of Alabama at Birmingham School of Optometry, has revealed the blinking frequently helps keeps the front surface of the eye moist.

"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 Elder.

There are other ways to protect sight and avoid computer vision syndrome, Elder said.

Undergoing a regular comprehensive eye exam eyes and wearing correct eyeglass or contact-lens can help avoid computer-related eye woes.

Just 20 seconds of rest to eyes can help prevent dry eyes. Even using a humidifier will help boost eye moisture.

"Special glasses and computer screen filters are available to help reduce glare and discomfort," Elder said.

Pre-existing, uncorrected vision problems like farsightedness, astigmatism and age-related eye conditions may also contribute to computer vision syndrome.
