What is computer vision syndrome? CVS refers to a variety of vision-related symptoms that occur when you regularly work at a computer workstation for two or more hours a day. Studies show that 50% to 90% of computer users experience CVS syndrome, and most are not even aware they have the condition. With increased computer use by children and teens, optometrists are reporting increasing numbers of youngsters exhibiting symptoms of CVS.
Eyestrain symptoms require your awareness and professional attention. Some of the symptoms identified by optometrists include: eyestrain, watery eyes, dry eyes, blurred or double vision, difficulty focusing, a heavy feeling of the eyelids or forehead, after-images, temporary nearsightedness, headaches, neck and back aches. Any of these can negatively impact your mental and physical wellbeing as well as your productivity.
Glare and other factors causing eyestrain and Computer Vision Syndrome (CVS)
The American Optometric Association has also noted three factors particular to children's computer use that is impacting their vision:
Ergonomic experts urge parents and teachers to be continuously aware of the positioning and computer practices of children. The length of time children use the computer should be monitored and breaks required. Their desks, keyboards, and monitors should be ergonomically adjusted for the child's height and computer usage. Room lighting and causes of glare should be eliminated. Another very important step is to talk with the children and let them know that blurry vision and odd sight issues are not normal and should be brought to someone's attention.
What can you do to minimize Computer Vision Syndrome?
There are several suggestions made by many professionals to correct computer work environment situations that can lead to the eyestrain symptoms or other manifestations of CVS directly related to the computer work environment. Test your work station and make sure the following recommendations are in place:
Consider using computer filters for anti glare screen benefits. Glare screens and computer monitor hoods are available for LCD monitors and are very useful in reducing eyestrain symptoms caused by lighting glare. They are easy to attach, most simply hook over the top of your screen, and they make a big difference.
Magnified vision, too. You can also purchase a magnifier computer filter that can double the size of your screen's characters without distortion. While not suitable for serious eye diseases, a computer screen magnifier offers viewing convenience.
