Scotopic Sensitivity

Scotopic Sensitivity, also known as Irlen Syndrome is a visual perceptual problem. The problems lies in how the visual information is decoded, it is not a medical eye condition. People with Scotopic Sensitivity 'see' the printed page differently to others and may even be unaware of this. This can lead to slow and inefficient reading, poor comprehension, fatigue and limited attention span.

Many people with Scotopic Sensitivity report that the text on the page appears to dither, making reading difficult. Educational Psychologist Helen Irlen observed in 1980 that coloured overlays helped students with Scotopic Sensitivity to read with greater ease.



 

Instructions

Clicking once on the text will cause it to dither, a further click will introduce a coloured overlay and a further click will return to the start position.
