Watch Out For Eye Strain


Parents have two more items to add to their back-to-school checklist: an eye check for their children and a review of their computer workstation for possible causes of eye strain.

Light sources should not be visible when sitting directly in front of the monitor

One out of two children spends more than four hours a day in front of a computer screen, according to the American Optometric Association (AOA).

The association warns that many children may be developing Computer Vision Syndrome due to prolonged computer use. “Computer use is an increasing source of vision problems, and children may experience many of the same symptoms as adults. Too much time in front of a computer screen can lead to eye discomfort, fatigue, blurred vision and headaches,” optometrist Leonard Press, a vision-learning specialist with the AOA, said in a prepared statement.

According to the association, parents should be aware that an adult computer workstation may not be suited to a child, who may have to look up at a higher angle than an adult. Parents should invest in a chair that can be adjusted for the child’s height. The recommended distance between the monitor and the eye for children is between 18 and 28 inches.

Children may work or play on a computer with a lot of glare for a long period of time without turning down the lights in the room to reduce the glare.

Parents can check for sources of glare by sitting in front of the computer. Windows or other light sources should not be directly visible when sitting in front of the monitor. Holding a small mirror flat against the screen can help pinpoint light sources that are reflecting from above or behind.

At the same time, kids’ eyes may lose the ability to focus on other objects because of extended computer time. The association recommends that children take at least a 20-second break for every 20 minutes of computer time.
