What is Digital Eye Strain?

Digital Eye strain, also known as Computer Vision Syndrome (CVS), is a term used to describe a group of eye and vision-related problems resulting from prolonged usage of digital devices like mobile phones, laptops, tablets and e-readers.

Initially, the problems of digital strain were mostly restricted to computer usage at the workplace. But over time, with the development of portable digital devices with smaller screens, Digital Eye Strain has become more widespread and affects individuals at all life stages.

Causes

Tips to prevent and reduce Digital Eye Strain

Issues related to viewing environment

Improper posture
while viewing

Choose your chair with care

  • Opt for a padded, ergonomic chair
  • Adjust chair height so that your feet are flat on the floor
  • Ensure adequate support for arms while typing

Poor
lighting

Pay attention to room lighting

  • Do not allow bright light to come in your field of vision while viewing the screen
  • Ensure that the overall illumination of the room is not more than three times brighter than your screen

Screen is
too bright

Avoid screen glare

  • Use a lighter background on your screen
  • Adjust screen brightness and contrast to optimum levels
  • Keep your screen clean of dust
  • Position the screen to avoid glare from windows or overhead lights
  • Use anti-glare filter to decrease the amount of light reflected from the screen

Wrong screen angle

Position the screen (and yourself) correctly

  • Proper viewing distance is 20-24 inches
  • Correct viewing angle is 10 to 20 degrees from the mid screen to the top of the screen
  • The larger the monitor, the greater the viewing area, causing less strain
  • Place any reference material alongside and as close to the computer screen to avoid frequent eye, head movements and focusing changes

Issues related to viewing behaviour and work practices

Long viewing hours

Remember to give your eyes a break

  • Follow the 20-20-20 rule
  • Take a 20 second break to view something 20 feet away every 20 minutes
  • Look left to right a few times, then in a triangular motion a few times, then reverse the directions

Staring at screen
without blinking

Make a conscious effort to blink more often

  • It will keep the surface of the eye moist and minimise the chances of developing dry eye
  • You can also use lubricating eye drops to reduce discomfort due to dry eyes

Issues related to existing eye conditions

Uncorrected vision
problems like myopia,
and astigmatism

Opt for regular check ups

  • Your existing eye condition could cause Digital Eye Strain
  • Schedule an appointment with us for a comprehensive eye check up
  • If you already wear glasses, do a check up to see if your power has increased

Make sure
you are using
the right glasses!

Always use prescribed spectacles and high quality lens

  • Use glasses with anti-reflective coating to prevent glare and reflections
  • Use blue light blocking glasses. They can also help to normalise circadian rhythm and reduce risk of macular degeneration.
