IRLEN SYNDROME
IRLEN Syndrome, formerly known as Scotopic sensitivity syndrome (SSS) causes a distorted world.
This leads the person to tension and a feeling of fatigue. The reason is that the brain is unable to process some radiations of natural light and thus more brain centers are activated than are needed to process visual stimuli.
Irlen syndrome is claimed to be hereditary and affects 13% of the general population. It affects men and women alike. It also affects 46% of people with dyslexia or learning difficulties, 55% of people who have suffered a stroke and 33% of people with attention deficit hyperactivity disorder.
The syndrome can also be experienced by people with vision problems who are not fully treated by an ophthalmologist.
