What Causes Computer Vision Syndrome?

Eye problems that are caused due to the computer can be termed as Computer Vision Syndrome. Staring a computer screen has become a part of our daily lives, for many of us. Work and pleasure both include using a computer or a tablet. Looking at this screen for prolonged periods can cause many problems including strain, pain and stress due to the repeated eyeball movements and non-blinking nature of the work that we do when we stare at a screen for many hours.

Let us find out more about the causes of computer vision syndrome or CVS:

  • Repeated Movements: When the same motion is carried out on a continuous basis, it can lead to stress based injuries due to the strain and stress caused in that part of the body. Much like carpal tunnel syndrome and other injuries like tennis elbow and shoulder joint problems, this condition is also caused due to the constant and repetitive movements which are known to lead to stress injuries. The longer you continue the activity, the worse it is bound to get.
  • Focus: When you sit in front of a computer screen and work, one of the most important things that you are doing is called focus. When you focus on a screen on a continuous basis, to align your eyes with what you need to read or see, you are causing long term damage if this activity is carried out for too many hours on a daily basis. This back and forth motion that makes us focus can lead to pressure and strain on the eyes, which should be broken by concentrating on other activities like writing on a paper or reading from a book.
  • Eye Muscles: These types of movements and activities can actually put a lot of pressure and undue strain on the muscles of the eyes. Also, things become even more difficult for the delicate eye muscles with the glare and blue light emanating from the computer screen which also has other elements like a flicker. This causes the eyes to align themselves by putting pressure on the eye muscles, which makes working on a computer that much more challenging than reading a book.
  • Wrong Glasses or Lenses: If you have nearsightedness or farsightedness, then these problems can become even more severe due to this kind of condition. Also, if you are wearing the wrong prescription glasses or lenses, your eyes are bound to suffer even more when you stare at a screen for such a long time.

Apart from all these factors, working on a computer gets even more challenging after a certain age like your forties. If you wish to discuss about any specific eye problem, you can consult a specilized opthamologist and ask a free question.
