Irlen syndrome

 ( Vision ) 

Irlen syndrome (or scotopic sensitivity syndrome) is a purported medical condition of disordered visual processing, which, it is proposed, can be treated by wearing colored lenses. The ideas of Irlen syndrome are not supported by scientific evidence, and its treatment has been described as a health fraud.

History The condition was proposed in the 1980s. Early studies investigating Irlen syndrome as a treatable condition have been criticized for taking a biased and subjective approach to the research.

The ideas of Irlen syndrome are pseudoscientific and not supported by scientific evidence.

Irlen method The Irlen method uses colored overlays and tinted lenses in the form of glasses or contact lenses. The method is intended to correct visual processing problems; it is claimed the resultant retiming of visual signals in the brain improves symptoms associated with Irlen syndrome.

Treatment of Irlen syndrome has been described as a health fraud that takes advantage of vulnerable people.
