computer vision care
Computer Eye SyndromePeople suffering from “computer eye syndrome” may experience eye fatigue, eye strain, blurred vision and glare related headaches.
These maladies can be greatly reduced by using special lenses set to focus at your “computer working distance” (usually 20 to 21 inches). These lenses are anti-reflective lenses, which means they reduce the glare that causes eye fatigue.
By sharpening visual performance, these lenses help you see with more clarity. Clarity with less glare helps your eyes feel better at work. Long hours in front of a computer screen and harsh fluorescent lighting can really make for tired eyes.
Using the PRIO computerized vision testing system, we can help ease the strain of sore, tired eyes by fitting you with special PRIO computer glasses. For more information on the PRIO vision testing system, refer to our “OPTICAL PRODUCTS” section of our website and visit the “PRIO COMPUTER EYEWEAR” page.

Computer Vision Syndrome Facts
- DEFINED Computer Vision Syndrome is a group of eye and vision problems related to near work that people do related to computer use, according to the American Optometric Association.
- SYMPTOMS Eye fatigue, together with headaches, blurred vision, dry eyes and general fatigue; sore back and neck.
- WHO’S AFFECTED Anyone who spends several hours a day working at a computer. Even in their 20s if they don’t need bifocals or reading glasses, they can still have symptoms, stresses and strains.
- HOW MANY The U.S. Occupational Safety and Health Administration estimates that more than 90 percent of the 70 million U.S. workers who use computers longer than three hours per day experience CVS.
- WHY IT HURTS Computer users don’t blink enough to keep eyes moist; they compensate to see the screen by bending their heads down to look over glasses or holding chin up to see through lower part of lenses, causing aches; eyes get strained by overhead lighting.
- NEED TO KNOW Vision questionnaire asks what kind of overhead lighting is above work station; how long you work on a computer each day; what symptoms are experienced; distance from eye to keyboard, eye to computer screen and reference material.
9 Ways To Reduce Computer Eyestrain
- GET AN EYE EXAM According to the National Institute of Occupational Safety and Health, computers users should have an eye exam before they start working on a computer and once a year thereafter.
- USE PROPER LIGHTING When using computers, lighting should be about half that used in most offices.
- TAKE FREQUENT BREAKS Full-time computer users should take a 10-minute break every hour.
- REFOCUS YOUR EYES Look away from your computer screen every 10-15 minutes and focus for 5-10 seconds on a distant object.
- BLINK MORE OFTEN Studies show that people blink less often when staring at a computer. Tears coating the eye evaporate more rapidly during long nonblinking phases and cause dry eyes.
- MODIFY YOUR WORKSTATION Place written pages on a copy stand adjacent to your monitor. Properly light the copy stand. Adjust your workstation and chair to the correct height. Use ergonomic furniture to assure proper screen locations and posture.
- MATCH THE COMPUTER SCREEN TO THE BRIGHTNESS OF THE ENVIRONMENT The contrast between the background and on-screen characters should be high.
- MINIMIZE GLARE Use window shades, blinds or drapes to block out excessive sunlight or install an anti-glare screen, to minimize reflections.
- EXERCISE Stand up, move about or exercise frequently.
