British optometrists are no longer advised to recommend coloured filters or lenses for the treatment of dyslexia.

Yeah but, no but, this is contrary to the 2018 UK Governments "Accessibility Regulations ?

As they have recognised 10% or 43,000 civil servants will be Dyslexic and the Health and Safety Executive Better Display Screen RR 561 2007 identified 58% of DSE operators suffer debilitating Screen Fatigue and Computer Vision Syndrome, myopic and asthenopic disease / 2D monocular adaptations.

Let alone "International Accessibility Regulations" WCAG 2.1 "Colour Contrast Validation" for e-learning and websites along with companion ISO 30071.1 DSE "Colour Contrast Calibration" mitigating early onset eye-strain, blurred or worse double vision !!!

It is also known that visually impaired, Neurodiverse and Dyslexics are at a '4' to '7' fold increased risk of induced visual repetitive stress injuries over-exposed to the near and close-up, causal factor in amblyopia, lazy-eye, eye-turns, convergence insufficiency, astigmatism, strabismus etc, etc.

In accordance with Accessibility Regulations Schools are required to produce an "Accessibility Maturity Report" annually covering Diversity and Inclusion so, without implementing Colour Contrast Validation and Calibration or children's Display Screen Devices, I for one, do not know how they are going to report gains in literacy for the 30% excluded from participating in learning if they have not been enabled to "Access Text"???

Can't help but wonder whether the reading or literacy and learning battle is expediently a "commercial one" rather than accepting and acknowledging 200 plus years of empirical evidence surrounding the consequences of binocular vision stress from over-exposure to the near or close-up in education.
