Visual Processing Disorder, also known as Irlen® Syndrome, appears to be caused by a defect in one of the visual pathways that carries messages from the eye to the brain. This defect causes a timing fault in processing visual information.
It is as if the brain was a radio and the frequency selector was not quite on the station, so that static interfered with the reception.
A Visual Processing Disorder cannot be identified through standard psychological, educational or optometric testing. It is not an ophthalmological or optometric problem, but may co-exist with it.
It can affect both adults and children, manifesting itself differently for each individual and interfering with a range of activities which can be a lifetime barrier to learning.
