Impact of Computer Use on Children



The impact of Computer Vision Syndrome on children

According to the American Optometric Association (AOA), parents should consider these issues concerning their children’s use of computers:

  • Children have a limited degree of self-awareness. Prolonged activity without a significant break can cause eye focusing problems and eye irritation. These problems may occur as the eyes' focusing system "locks in" to a particular target and viewing distance.  In some cases, this may cause the eyes to be unable to smoothly and easily focus on a particular object, even long after the original work is completed.

  • Children are very adaptable. As a result, children often work in an unhealthy situation — such as with glare on the computer screen — and might not even think about changing the computer arrangement or surroundings to achieve more comfortable viewing. This can result in excessive eye strain. Also, children often accept blurred vision caused by nearsightedness (myopia), farsightedness (hyperopia) or astigmatism because they think everyone sees the way they do.

  • Children are not the same size as adults. Most computer workstations are arranged for adult use. Therefore, a child using a computer on a typical office desk often must look upward at a higher angle than an adult. Since the most efficient viewing angle is slightly downward about 15 degrees, problems using the eyes together can occur.

  • Use of computers with less than optimum lighting.The lighting level for the proper use of a computer is about half as bright as that normally found in a classroom. Increased light levels can contribute to excessive glare and problems associated with adjustments of the eye to different levels of light.
