Digital Eye Strain

What is Digital Eye Strain?

Digital Eye Strain or what is also known as Computer Vision Syndrome is the physical discomfort felt when using screens and other digital devices such as desktop and laptop computers, tablets, e-readers and mobile phones at close or mid-range distances for prolonged periods of time^1^.  It is temporary^1^; however, the discomfort it causes can be minimized by following a few simple steps.


We now live in a world where staring at screens for long periods of time is all part of a normal day. On average, high digital users can spend 10 hours or more staring at screens per day^2^. There are a number of factors that determine the amount of strain our bodies feel as a result of this. These include^1^:
• Lighting in the room
• Time spent looking at the screen or device
• Viewing distance from the screen
• Screen size
• Number of screens being used at the same time
• Viewing angles
• Glare on the screen
• Seating posture

One or all of these may combine to cause an uncomfortable amount of strain on our bodies.
