Vision and Computers
Most people who use a computer for prolonged periods ex. on the job, at school or at home including children may be at risk for computer vision syndrome (CVS) which is the use of a computer for many hours uninterrupted. Symptoms include: headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, and difficulty refocusing the eyes. These symptoms can worsen with improper lighting conditions (i.e. glare or bright overhead lighting or overhead vents, direct air from a fan.
Treatment includes: eyeglasses such as single vision computer glasses, bifocals or progressive additional lenses called task lenses specific to the computer. Taking frequent breaks is critical to reducing fatigue. The 20-20-20 Rule recommends getting up and moving away from your computer for short breaks at least every 20 minutes. Take a few minutes to stretch your arms and back, and let your eyes relax their focus by looking at something at least 20 feet away. Blinking fully and frequently will help to reduce your risk of dry eyes from computer use.
