In today’s hi-tech world the relationship of the eye and the computer screen is becoming a topic of concern in medical fields. Studies have found that up to 70 percent of computer workers worldwide experience symptoms of Computer Vision Syndrome, or CVS.
Unfortunately, Computer Vision Syndrome is not only limited to the adult population. Many children are involved with computers in their school and home environments. Hours spent on computers by children can result in the same vision stresses experienced by adults. CVS in children can have a profound effect on the normal progression of their vision maturity.
Symptoms of Computer Vision Syndrome usually appear after 2 or more continuous hours of work on the computer. Headaches, wandering focus, itchy or watery eyes, double vision, and blurry vision are the most common symptoms. Other symptoms also occur and can even include muscle and joint aches, especially in the shoulders and neck.
Harder to Focus On
CVS results from the affect of the computer screen on the eye. Eyes do not read and process characters on a computer screen the same way they process printed materials. Printed characters have crisp edges and high contrast levels making it easy for the eye to focus.
Characters on the computer screen are less defined. Each character is composed of small dots of light that are bright in the middle and fade towards the outer edges. Just as the images fade, our eyes wander across the characters and have difficulty finding a focal point. We must force our eyes to focus which creates a strain.
When reading printed material the eyes automatically find the RPA, the resting point of accommodation. Once this point is determined the eyes can comfortably read the text. The eye has difficulty relaxing on the RPA on the computer screen. The eye wanders and must be forced back to the focal point. This is the cause of eye tension and CVS.
Computer Reading Glasses Work
Is there help available for Computer Vision Syndrome? Yes! Computer reading glasses can greatly ease the symptoms of CVS. Reading glasses work to reduce eye strain and make it unnecessary to constantly look for a focal point when reading text on a computer screen.
Computer glasses have the added benefit of helping in the workplace. Workers who wear computer reading glasses show fewer mistakes in their work and a marked increase in output. This result is due to less stress caused by vision strain.
One drawback to computer glasses has been the fear that they may resemble safety glasses. This fear can be put to rest. Lenses for reading glasses are placed in fashion forward spectacle frames. This includes reading glass styles such as ½ frames and full frames.
Many people who work with computers regularly usually have several pairs of eye glasses instead of just one. They keep the glasses handy by storing a pair near the home and work computer while also carrying a pair for reading computer screens in department stores or at the library.
In fact some people will have reading glasses stored in every room in the house including the kitchen where so many newspapers are read and the bedroom for reading a book before falling asleep. You can keep a pair in the car too so that you always have reading glasses available no matter where you go.
