In focus: Overlays - do ECPs and SEN teachers need more training?

Recent advice for special education needs teachers about testing children for visual stress or dyslexia has suggested they do not use coloured overlays in case they misdiagnose any vision problems.

Treatment for these problems has often included the use of a Cerium Intuitive Colorimeter, which allows people with visual stress to best identify which colour alleviates their symptoms when reading. People are then either given an overlay in their chosen colour to help their reading or they are prescribed precision tinted lenses applied to glasses. The prescribing of different colours has also helped to eliminate certain levels of glare for those with pattern-related perceptual glare problems.
