Do you need a check for Computer Vision Syndrome (CVS)?

In fast paced era of Digital lives- Technology, no doubt, has shrunk the world! Look at any sector, computers and other high tech devices are here to stay. Jobs (private or government sector), schools or even higher studies, all have gone online. To get a glimpse of a tiny tot downloading a you tube video is not uncommon these days. In a way, we all have fallen to this indispensable monster.

Since access to computer, smartphones, other gadgets and world wide web access is must in almost every task or work. One needs to be aware that prolonged access to computer/laptop/tablet/mobile phone for any purpose namely; work/entertainment/ assignment/ reading/ presentations/gaming/ social networking or any other have arisen all new health issues. Desk or computer related musculoskeletal diseases like carpal tunnel syndrome etc. varied problem in eyes have also mushroomed. Prolonged/ uninterrupted hours spent over these gadgets may lead to eye strain. Computer Vision Syndrome (CVS) is a condition that strains the eyes. Digital Eye Strain is another name for CVS.

The most common symptoms for CVS can be a strain and dryness felt in eyes, blurring of vision, frequent headaches. These symptoms may be subtle initially but may aggravate if ignored or incessant hours spent in front of light emitting screens. It may also lead to uncorrected visual problems like farsightedness and astigmatism, inadequate eye focusing or eye coordination abilities, and premature aging changes in the eyes, for example presbyopia (hardening of the eye ball) can all contribute to the development of visual symptoms when using a computer or digital screen device for on regular and prolonged hours.

Apart from just the continuous light emission there are other factors that can be attributed for CVS like improper light in the environment, improper/too acutely or obtusely placed screens, screens placed too close/far, excessive glare at the screen, inappropriate font size/colour may put excessive pressure on the eyes. Unlike early days when these innovations had just set out in the market, these screens are no longer a status symbol rather a necessity as it is required in every walks / sphere of life.

If this exposure to screen light is unavoidable then how to avoid these health threats??

A stitch in time saves nine is the most suitable proverb in this case as small timely tricks/steps can work wonders. American optometric association came up with a 20-20-20 rule to ease out these symptoms and prevent these symptoms to take the shape of any grave eye disorder. 20-20-20 rule states to take a 20-second break to view something 20 feet away every 20 minutes (considering the average seven hours spent by the American worker).

But the scenario is little different in India where enormous time is spend after the usual work schedule. Even for rejuvenation activities, people find solace in front of the light emitted by these screen.

  • Another simple trick includes keeping the screens (computer) at adequate height: 15-20 degrees below the eye level is mostly preferred for comfortable viewing.
  • Using anti-glare screen also makes a good option.
  • Frequently blink eyes while working.
  • Take frequent breaks while working. Try to turn your face (eyes) away from the source of light emitting device
  • Use a comfortable, well cushioned and ergonomically designed chair that allows to sit at a proper height so that feet rests properly on floor.
  • In case it is required to frequently peep over the reference notes, place them at a position so that head rotation is not required.
  • Wash eyes frequently with water  
  • Since it is nearly unavoidable to not look at those screens, therefore try these simple hacks and enjoy viewing. In case any of the symptoms become agitating, get an eye check up done for CVS.

Experience happy and healthy viewing…
