What is Irlen Syndrome?

Irlen Syndrome is a hereditary, visual-perceptual problem that prevents an estimated 14-18% of the population from being able to read efficiently. Irlen Syndrome is not a vision problem of the eye. Irlen Syndrome is the visual-perceptual reception site of the brain perceiving the timing of light waves ineffectively. The disorder remains undetected by standard educational, visual, and medical tests.

Individuals with Irlen Syndrome perceive the printed page and sometimes their environment differently. Unlike those without the disorder, reading becomes more difficult over time and physically exhausting. Also, it can affect attention span, listening, energy level, motivation, and work production.

Others may view individuals with Irlen Syndrome as underachievers or as having behavioral, attitudinal, or motivational problems. Irlen Syndrome often coexists with other learning difficulties and should not be held in isolation as the only existing problem. Some people already diagnosed with learning difficulties may be suffering from Irlen Syndrome in addition. More importantly, it should be stressed that the treatment for Irlen Syndrome is not a cure-all but rather a piece of the puzzle for the individual.

Diagnosis and Treatment

Color alters the timing in which the person receives and processes much like photographers use colored filters for various effects ( Yellen-Schweller Effect ) . The patented Irlen Treatment Method uses precision-tinted filters, worn as glasses, to reduce visual-perceptual difficulties and light sensitivity.

The evaluator performs an initial screening to determine whether or not the individual is suffering from Irlen Syndrome. The assessment includes the use of colored overlays versus white pages to assess possible improvements. If the evaluator determines that the individual has Irlen Syndrome, a full diagnostic tint evaluation is recommended.

The diagnostic assessment is an in-depth evaluation to determine the most beneficial color. After determining the specific tint, the Irlen laboratory utilizes a computerized spectrophotometer to place the exact tint on the lenses.

Positive results obtained from the use of Irlen Lenses™ may include: improved reading accuracy; better comprehension; increased reading speed; increased productivity; reduced strain and fatigue; improved academic and work performance; and reduction of visually- induced headaches and migraines.
