Colorimetry & Visual Stress

Discover how colour may alleviate visual discomfort and help with dyslexia.

Visual stress is a term used to describe visual discomfort and perceptual distortions in the printed text, suffered by many people who struggle to read comfortably. The condition is estimated to be present in about 40 % of poor readers and in 20 % of the general population in varying degrees.

 

Coloured overlays may improve reading speed and accuracy. They may enable longer periods of reading free of discomfort. When they do, this is an indication that the individual may benefit from Precision Tinted Lenses. These lenses are prescribed using specialist equipment called a Colorimeter.
