While operating on a screen, the eyes must continually concentrate and refocus. When you learn, they switch back and forth. You can have to glance at documents and then type them back. Your eyes respond to images that continuously rotate, alter, transfer focus, and submit images to the brain rapidly. All of these positions need a lot of eye muscle commitment. And unlike a book or text, the screen adds colour, blinking and glaring to make matters worse. Moreover, it has been shown that weblink even less often on a screen that allows your eyes to dry up and obscure your vision regularly at operation.


The most common symptoms associated with CVS


  • Eyestrain.

  • Headaches.

  • Blurred vision.

  • Dry eyes.

  • Neck and shoulder pain.

What can you do


Follow rule 20-20-20 as a simple solution for this. Look away from the computer every twenty minutes, then something around 20 feet away about 20 seconds. 


Visit the eye doctor frequently for tests and to hold your medications up to date. Let them know about any issues you have. You may require glasses or contact lenses. They’ll determine whether you should use your usual glasses for computer work or whether you need a special pair. They might recommend a single or bifocal lens, or tinted lens material to improve contrast and screen out glare.
