Understanding Computer Vision Syndrome

Share on

Looking at digital screens for long periods can lead to a range of eye and vision problems. Computer vision syndrome (CVS) can be caused by all digital devices, not just computer screens, and as digital device use is on the rise and with more people looking at digital screens for longer, cases of CVS are also increasing.

Common symptoms of CVS include:

CVS causes

  • Prolonged screen use: your eyes have to work harder when staring at a screen, adjusting in different directions and changing focus. Our blink rate can almost half and we often squint, causing dry eye.
  • Computer games: gaming is linked to eyestrain, as the eye is forced to jump frequently between different points of focus.
  • Environment: poor lighting, screen glare and bad seating posture.

Did you know?

Uncorrected vision conditions such as long-sightedness, astigmatism and presbyopia will make you squint and strain your eyes when using  digital devices – increasing your chances of developing CVS.
