What is the Irlen Method?
The Irlen Method is a two-step process: problem identification and colour identification and requires two testing sessions. The colour (which is different for each person) is the key to the success of the program and can only be determined after a diagnostic assessment performed by a certified educational professional trained in the Irlen Method.
The first testing session determines whether you have Irlen Syndrome and can be helped by the Irlen Method’s colour technology. In this session, we determine how severe your problem is and whether colour can help eliminate your difficulties. Your correct coloured overlay combination is determined at this time. Both certified Irlen Screeners and Diagnosticians can test for coloured overlays.
The second testing session is only for individuals who show moderate to significant improvement with coloured overlays. In this session, we target the precise wave lengths of light causing your problems by using a limitless number of colour filter combinations. Your precision colour is worn as glasses or contact lenses. The colour worn as glasses will not be the same as your plastic overlay colour. If your problems are related to math computation, copying, depth perception, light sensitivity, and headaches, coloured glasses are your best treatment option because they correct problems with the printed page and also the environment.
Importantly, wearing the wrong colour can actually cause or worsen your problems. The testing to identify your correct coloured glasses can only be conducted by Certified Irlen Diagnosticians/Clinics.
Coloured lenses provided by optometrists and vision specialists to treat reading problems are NOT the same as the Irlen Method. These professionals do not have the right colour, or diagnostic process for colour selection. Inaccurate colour selection can result in headaches, eye strain, and fragmented brain processing resulting in more distortions and reading problems.
