Computer Vision Syndrome (CVS), also called Digital Eye Strain, is a term that covers eye-related problems caused by prolonged usage of electronic screens (phones, tablets and computers). When these screens are viewed for long patients will experience eye discomfort and vision problems and these problems seem to increase with prolonged screen usage.

Many parents and guardians have found electronic devices very useful in keeping the children occupied, but have not thought of the damage these devices are causing to the eyesight. One major effect of long term computer use in children is an increased risk of them developing early macular degeneration.

Many are not aware of ways to prevent damage and therefore have not taught their children the correct way to use these devices. While technology is steadily becoming indispensable in child education, it is important to teach them the proper way to care for their eye health.


Take special note and watch their screen time when children complain about:

  • Dry eyes
  • Pain in the neck or shoulders
  • Eye strain
  • Headaches
  • Blurred vision


  • The 20-20-20 rule: all children should learn to pause whatever they are doing on their device and take a 20-second break to view something 20 feet away every 20 minutes.
  • Taking note of and cutting down on screen time: Increased screen time can lead to the development and progression of short-sightedness.
  • Reducing the brightness of the device: Show them how to reduce the glare of the screen, which can cause eye strain.
  • Using anti-reflective lenses: these lenses help filter blue light which is the harmful portion of the light emitted by the computer.
  • Reading in proper light: Using a device in a darkened room causes more strain to the eyes.
  • Good sitting posture: Train them to sit and hold the device properly to prevent pain in the back, neck and shoulders. Also, teach them to exercise their wrists and fingers when using the devices.
  • Proper handling: Teach them not to hold the devices too close to their faces. If the child seems to be having difficulty reading within the appropriate distance, consider an eye test to know if the child is already experiencing an eye defect.
  • Blinking regularly: These devices make the children stare which dries up the front of their eyes. Teach them to remember to blink regularly and deliberately.

Children will use technology. It’s up to their parents and guardians to make sure that they know how to use it properly and in a manner that protects their health. Contact us for more information on how to take care of your child’s eyes.
