Irlen Syndrome is thought to affect about 50% of students with specific learning difficulties, such as dyslexia.
It was in 1983 that an American psychologist Helen Irlen discovered a perceptual problem caused by light sensitivity.
Irlen found that some students benefited from the use of coloured overlays. The overlays seemed to work by filtering out light that caused distortions to print. The problems appeared to be worse with black print on white paper.
