Screen Fatigue – the Science.

What is screen fatigue?

Screen fatigue is the name given to a cluster of symptoms that arise from looking at a digital screen for prolonged periods of time.

The symptoms can be felt as eye strain, dry eyes, headaches, overall tiredness with reduced productivity, blurred vision, a sore stiff neck and struggling to see.

There are several names that it comes under, depending upon where you are in the world, and these are:

Eye strain

Zoom fatigue.


Computer vision syndrome

Working with display screens means staring at the close up, looking at sharp contrasts of colour, navigating vertical and horizontal lines and these together impact our vision. Add the glare of the screen and eyes, like most organs, if you work them too hard, they become tired.

Looking at a screen all day makes our eyes constantly re focus, again and again, and this tires them out, leading to the above-mentioned symptoms.

Why does it tire our eyes?

Humans are designed to look at nature. Nature on the whole doesn’t use many sharp colour contrasts, there are not many naturally occurring straight lines and we scan the close up and the horizon, giving our eyes their full range of movement.

Humans are not designed to be sitting at a desk, staring at a glowing screen.  

Too much of this and we become short-sighted.

Research is showing us that screen fatigue is not a temporary effect of working with a screen for more than an hour a day, it’s showing that it causes real, long term harm.

Screen Fatigue is impacting business to the tune of £36 billion a year, and if we are not careful, it’s going to impact the lives of future generations.

To fully understand how we arrived here, please sign up for our newsletter and we’ll and send you our white paper. It’s a long read, but it delves into the background of why we as humanity, are facing a pandemic of shortsightedness.

And yes, we use the word pandemic deliberately.

Our white paper explains the history and debates held between scientists throughout the ages and will help you to understand how fatigue affects visual and cognitive deficits, plus the practical and technological solutions to combat it.

We’ve put together a collection of research articles quoted in the white paper and a video that we feel give a balanced overview of the situation so that again, you can gain a full understanding of why combatting screen fatigue is urgent.

If you feel you suffer with screen fatigue, give our therapeutic Display Screen Optimiser a try. It’s a reading challenge that takes about 15 minutes and allows us to find the best colour contrast for your screen, which you can then download and start using straight away to mitigate your risk, and as one customer said – ‘soothes their eyes’.

Our patented Display Screen Optimiser has helped many to increase their reading speed and mitigate the risks of screen fatigue.
