Words moving on the page, glare from white paper, headaches after reading — these are not imagined. Scotopic sensitivity is a real neurological condition that coloured overlays and precision-tinted lenses can significantly relieve.
Irlen syndrome — also called Meares-Irlen syndrome or scotopic sensitivity syndrome — is a processing problem affecting how the brain processes visual information from the eyes. It is not a problem with the eyes themselves; it is a sensory processing difference that makes certain wavelengths of light difficult to process efficiently.
Many patients have lived with these symptoms for years without knowing there is a name — or a solution — for what they experience.
A structured screening identifies the presence and severity of scotopic sensitivity. We use standardised rating scales alongside controlled reading tasks to quantify symptoms.
We systematically trial coloured overlays to identify the precise hue and density that produces the clearest and most comfortable reading experience for you.
For patients who benefit from overlays but need full-field colour management, we assess for precision-tinted spectacle lenses — more effective than overlays alone.
Irlen syndrome often co-occurs with convergence insufficiency or tracking problems. We assess for — and treat — any underlying binocular vision issues alongside the scotopic sensitivity management.
Overlay or lens colour requirements can shift as the visual system adapts. We review your prescription periodically to ensure optimal relief.
Irlen syndrome is more prevalent among individuals with dyslexia, ADHD, autism spectrum conditions, and traumatic brain injury — though it also occurs in people without any other diagnosis. It affects children and adults equally. Many people in high-reading professions (lawyers, accountants, academics) discover they have been managing the condition without knowing it.
