Computer Vision Syndrome (CVS) is a term used to signify the problems that occur due to staring at computer screens or other digital devices for long durations. With technology ruling our lives like never before, most of us are exposed to the glare from computers and other video electronic devices on a daily basis.
Reading a book for a long period of time puts a limited strain on your eye muscles due to the ‘constant’ nature (light, texture, page colour) of the book. On the other hand, computer screens glare, flicker and contrast. This creates a substantially higher strain on the eye muscles as they have to quickly adjust to the changing dynamics of the screens, thereby causing CVS. It is believed that CVS occurs to over 80% of computer and other VED (video electronic devices) users as most of us end up ignoring the initial symptoms and do not follow enough precautions to minimize the effects.
Some of the most common symptoms include:
a) Strain on the eyes
b) Feeling of dryness in the eyes
c) Blurred Vision
Although many of these symptoms could also manifest even in non-CVS cases, it is still advisable to get your eyes checked for any initial stages of this syndrome.
Using certain precautions go a long way in reducing or preventing CVS:
1. Take a break – Taking a few minutes off the computer screen and going for a short stroll might help you tremendously.
2. Minimize the glare – Try working on the computer after you’ve turned down the brightness level. It might seem to be a problem in the very beginning, but then your eyes will greatly benefit from this in the long run.
3. Position the Screen – Positioning the screen approximately 1.5 to 2 feet away from your eyes and just below your eye level will also reduce strain on the eyes.
