Computer Vision Syndrome (CVS)

CVS also known an Digital Eye Strain refers to a group of eye and vision-related problems following the extended use of back lit technology such as computers, tablets, e-readers and mobile phones. These problems occur because of the effort required by the eyes to keep the text clear and single at a close distance. (see 'Eye Teaming & Focusing') 

Problems that were once limited to office workers spending 7-8 hours/day in front of the computer, are now developing at a fast rate in younger populations due to the prolonged use (and reliance) of iPad's and mobile devices. There is even evidence to support a strong link between CVS and increasing Myopia (short-sightedness) prescriptions in patients. 

The most common symptoms of CVS/Digital Eye Strain include:

  • Blurry vision

  • Frontal headaches (around the eyes and forehead)

  • Pain in and around the eyes

  • Dry eyes

  • Neck & shoulder pain -> which can often lead to tension headaches


Causes of Computer Vision Syndrome

According to the AOA (2020), symptoms can be caused by:

  • Poor lighting

  • Glare from the digital screens

  • Uncorrected vision problems or incorrect glasses prescriptions

  • Incorrect ergonomic set up

  • Incorrect viewing distances


We offer a Visual Hygiene Consultation to assess your current environment, technology habits and possible triggers for CVS.
