Screen fatigue/Computer Vision Syndrome is harming your eyesight and sabotaging businesses.

It’s costing 20% in lost productivity and, if you are an employer, it’s leaving you open to lawsuits.

Our mission is to eliminate this modern disease and claim back lost efficiency using our patented software.

Let us screen you for screen fatigue.

With our patented software, we’ll provide a personal, objective assessment of the best background Colour Contrast Values that are unique to you. Our self-administered, interactive online Display Screen Optimiser takes 15 minutes to complete. Take a look at The DSO Manual for the details.

We provide colour codes, a Windows theme, plus instructions for setting up the optimal screen background colour. This will help prevent screen fatigue/computer vision syndrome, which may also increase reading speed, and increase your productivity. Sign up is in the box. The cost is just £1 to cover admin charges.

Eye Science and Workplace Fatigue  

Fatigue affects every aspect of our lives and eye science is continually discovering more. It’s telling us more about the consequences of computer eye strain in the 21st Digital Century, across education and work/life, and its impact on safety, performance, and health.  

In our 25-page White Paper – (that’s jam-packed with information. It’s a long read – about 24 minutes)  you’ll learn: 

  • Why and how eye strain, affects vision and cognitive fatigue  
  • Fatigue in the workplace—its origins and consequences  
  • Practical and technological solutions to combat computer eye strain/fatigue

What can you do?

The first thing to do is to reduce the hazards of spending too long on your display screen equipment (DSE) and then suffering the debilitating symptoms of digital eye strain, know as Computer Vision Syndrome or Screen Fatigue.

Screen Fatigue is now recognised as a Global Pandemic affecting between 50 & 90% of users in education and DSE operators in the workplace, often manifesting as presenteeism, lost productivity and eye fatigue.

One simple routine that you can start right away is the 20-20-20 rule.  This is when every 20 minutes, you look at something 20 feet away for 20 seconds. 

The more legislative aspects to computer vision syndrome:

WCAG 2.1 Website Accessibility Guidelines and “Colour Contrast Validation” implementation are often very much down to you, and/or the designers.

However, the “reasonable adjustments”, adaptations and personal customisation/calibration of users DSE screens for accessibility, are not something that can be provided as a minimal “one size fits all solution.” For optimal results, they need to be individualised.


While screen text accessibility is not legislated for under DSE regulations, it is considered to be included under disability and accessibility. Meaning, it won’t be uncommon to see more claims “resulting from any omission” under the ADA or UK Equality Act. Proving that you have taken steps to mitigate this risk will go a long way towards protecting you against future litigation. Disability lawsuits are on the rise.


“Presenteeism” – staying at work despite being unfit for work, fatigued and remaining for more hours than contracted, yet not being productive – now accounts for an average 20% lost productivity or one day in five. It’s harming your workforce and leaving you open to disability lawsuits under the ADA and Equality Act in the UK, especially since the WCAG 2.1 and BSI ISO 30071.1 Accessibility Regulations came into force
