Computer Vision Syndrome (CVS) - Eye care

Updated on January 22, 2009

Computer Vision Syndrome (CVS)

With the increased use of computers, human visual system has led to series of visual symptoms called “Computer Vision Syndrome”.

What is CVS?

Computer Vision Syndrome is the complexity of eye and problems in vision experienced by the computer users.

Continuous exposure to computer monitor results in vision problems. Visual symptoms can mostly be resolved with the proper management of environment and proper eye care for the computer users.

Following are the common symptoms faced by computer users:

  • Eye tiredness
  • Eye irritation
  • Eye strain
  • Blurred vision
  • Headache
  • Neck and Back ache
  • Double vision

Above are the symptoms of CVS and if you face any of the above mentioned problems then you may suffer from CVS. DO NOT let your eyes go worse with increased power, consult your eye doctor and get his/her advice. 

Following are important instructions used to prevent Computer Vision Syndrome (CVS):

Blink your eyes

Blink count of eyes is 15 per minute. Normally we, computer users while looking at monitor, tend to forget to blink our eyes often (this is due to the concentration on work).

If you don’t blink your eyes in this rate, then eyes become dry and muscles become weaker. While blinking, eyes will get the needed moisture. So, it is very important to blink your eyes at least 15 times a minute.

Suppose you forget to blink your eyes in this rate, and then after every 20 minutes close your eyes completely for 20 seconds (at least) then slowly open your eyes. This will prevent your eyes being restless.

 

How and where the monitor should be?

Distance: 50 cms should be maintained between your eyes and the monitor.

Location: Centre of monitor should be 8 inches below the eye level.

Illumination: Lower brightness and higher contrast should be set and adjusted according to room lighting so that monitor does not act like a light source. This will avoid eyes being too sensitive to light.

Position: Straight ahead and tilted back 15 degrees.

Light Effect

Avoid light shining directly on your eyes or monitor. Use anti-glare screen. You can use curtains to control the amount of light entering the room.

20-20-20 Rule of eyes

After every 20 minutes of your work take short breaks for 20 seconds by looking at objects those are at least 20 feet away or just by closing your eyes.

Eye Exercise

  • Close your eyes completely and slowly roll your eyeballs clockwise and anti-clockwise. Do it for 10 times.
  • Move your eyes to the right end and then to the left end for 10 times.
  • Move your eyes up and down for 10 times.
  • Take a pencil, hold it 1 feet away. Now, concentrate on the tip of the pencil. Bring it close to your eyes and move it away. Do it for 10 times.

Repeat these exercises 3 times.

Vitamin A helps in keeping your eyes healthy. Following are major sources of Vitamin A:

  • Papaya
  • Carrot
  • Fish
  • Milk
  • Egg

 

Some useful tips for your eyes

  • To prevent and remove dark circles under eyes:

              Cut a potato into thin slices. Take two slices and closing your eyes, keep them on your eyes. This will give a cooling effect to your eyes and remove the dark circles below the eyes. Repeat this daily.

               You can also take this treatment with Cucumber slices. This also gives you a best result.

Do you suffer with annoying marks on the top of your nose because of your specs?

Follow these tips:

1.) It is mandatory that once in 3 months you change your specs' nose pad.

2.) Don't wear your specs tightly.

3.) For every half an hour you can take out your specs and gently massage on the spot where the nose pads touch your nose. This will let more blood circluation preventing the marks.

4.) Try wearing weight less frames.

5.) Adjust your nose pads slightly so that it doesn't annoy you.

6.) There are two types of nose pads: (1.) Soft pad and (2.) Hard Pad. Always use soft pad.

7.) If you already have marks on your nose due to specs wearing, then apply Olive oil in that area and gently massage. Within 2-3 weeks you will find the difference.

Is it possible to bring down the eye power to neutral from high power (-1.0,-0.75)?

      Hi friend, you have post article very great but I say eye care for personal computer customers

      The majority of our function is completed on computer systems, as well as there is certainly normally no escape from it. It’s a visually intensive job as well as, sadly, our function stress as well as lifestyles tend not to give us the chance to become sort to our eyes. http://bit.ly/gd5fLR

      Dear Kala,

      I am really proud of myself that at least someone is there to follow what i am doing. Basically, i posted this blog because i didn't follow (actually i didn't know) this information before. So, i ended up with wearing specs now.

      Now, i am following all these and wanted to share with people before they end up with how i am now. :p

      Thanks for your comments and i promise that i will keep continuing to provide such useful info (even before i get affected).

      Thumbs up and all the best. Share with people you really take care of.

      Hi bskvsdm, as you have already pointed out, when we work on a computer, we tend to stare at the monitor constantly for hours. Also our rate of blinking diminishes so that there occurs a drying of the ocular surface. This results in eye strain and chronically red and tired eyes. So, while working on a computer one must remember to blink at a steady rate. Also, since the moniter is illuminated there occurs a depletion of the pigments responsible for producing the sensation of "vision" after some time. So one should adjust the contrast properly. Also, use of artificial tear drops will relieve the CVS. Then, regarding removal of dark circles around the eyes by placing potato or cucumber slices on the eyes is a very helpful treatment and will definitely show results. You have done a professional job with this hub. Thumbs up.
