what is Irlen syndrome?
Irlen syndrome is the brain's inability to process full spectral light .It is not a visual impairment but because the brain is not able to process visual information , the result is a range of visual distortions in the environment and on the printed page.
People of all ages may experiences symptoms including light sensitivity ,headaches or migraines and difficulty or discomfort when reading.
when reading ,those with Irlen syndrome might see the words on the page flicker or blur ;the word seem to move and sometimes they see colours shapes or shadowy lines on the page. Understandably reading can become very tiring.
The condition is made worse by environment factors such as lighting , brightness ,glare and high contract patterns and colours. Black on white text, typical in school textbooks ,can cause the most discomfort.
