Follow the 20-20-20 rule to reduce eye strain

The average American worker spends seven hours a day on the computer, either in the office or working from home. To alleviate digital eye strain, follow the 20-20-20 rule: take a 20-second break to view something 20 feet away every 20 minutes.
Computer Vision Syndrome describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and cell phone use. The level of discomfort appears to increase with the amount of time spent looking at digital screens.
The most common symptoms include eyestrain, headaches, blurred vision, dry eyes, and neck and shoulder pain. They may be caused by poor lighting, glare on a digital screen, improper viewing distances, poor seating posture, and uncorrected vision problems.
Solutions vary. But Computer Vision Syndrome can usually be alleviated by obtaining regular eye care and making changes in how you view the screen.
In some cases, people who do not need eyeglasses for other daily activities may benefit from glasses prescribed specifically for computer use. In addition, eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Special lens designs, lens powers, or lens tints or coatings may help.
Some computer users experience problems with eye focusing or eye coordination that can't be adequately corrected with eyeglasses or contact lenses. A program of exercises for the eye, called vision therapy, may be needed to treat these problems. Vision therapy trains the eyes and brain to work together more effectively.
