Computer Vision Syndrome Overview
Computers are an important part of our lives. Research shows a rise in the detection of visual problems associated with computer use - referred to as computer vision syndrome.
Symptoms
- Headaches
- Eye strain
- Blurred vision
- Eye irritation
- Double vision
- Excessive tearing or dry eyes
- Pain in the eyes
- Excessive blinking
Prevention
- Position your screen about an arm’s length from your eyes and 20 degrees below eye level.
- Keep your room lighting the same brightness as your computer screen. Don’t stare at the monitor in a dark room
- Minimize reflected glare on your screen by using dimmer switches on lights and protective anti-reflection coatings on glasses
- Use the 20-20-20 rule. Every 20 minutes take a 20-second break and focus your eyes on something at least 20 feet away.
- Blink fully. People tend to blink less than half as often during computer use, which can result in dry eyes. Use of eyedrops prescribed by your Optometrist may relieve comfort.
- Ask for anti-reflection coatings on lenses of your glasses, that can be applied at the time of manufacturing, to protect your eyes from bright and/or flickering light sources such as fluorescent lights. Your Optometrist can recommend appropriate eyewear specifically suited for computer use.
Treatment
- Small uncorrected refractive errors such as nearsightedness, farsightedness, astigmatism or presbyopia can be corrected with eyeglasses or contact lenses to increase the efficiency and comfort when working at the computer.
- Eye muscle misalignment or deficiencies can be improved through eye exercises or vision therapy, which can reduce the focusing strain on the eyes.
- A routine eye exam will determine if you can benefit from glasses, contact lenses, or vision therapy.
