Information for Opticians
Irlen syndrome is a neurologically-based visuo-perceptual dysfunction. It affects the processing of visual information from the eye to the visual cortex and results in cortical hyperactivation.
As part of standard protocol followed by all Irlen practitioners, clients are required to have had a recent eye exam (ideally within the past 6 months) by a licensed eye-care professional (optometrist or ophthalmologist) prior to their initial Irlen testing. Irlen Syndrome is not an eye problem. Correcting for Irlen Syndrome will not resolve existing optometric problems; correcting existing optometric problems will not resolve issues associated with Irlen Syndrome. We work closely with optometrists and many optometrists and ophthalmologists are also certified Irlen practitioners.
The Irlen Institute can tint CR39 lenses provided that no anti-glare, anti-UV or anti-scratch treatments were applied. Those should then be accompanied by a valid prescription. We can also supply such lenses in plano or prescription. In this last case, a valid prescription is required, and P.D. measurement should ideally be added on to the prescription itself. In such event, the client will come back to you for cutting those lenses to fit the frame he purchased from you. We do not sell frames at the Atlantic Irlen Centre. If a sturdier lens is required, please contact us for more information.
For technical reasons, we will not provide progressive lenses because of the measurements required to be done with the client present. You are then required to supply the lenses, cut and assembled, with the exception being invisible frames, where the lenses need to be supplied cut but not assembled. The client will come back to you for re-assembly.
Some Irlen clients need the added protection of a wraparound lens. To provide a better fit, we ask that the client pick the desired frames at your office and have the lenses prepared and mounted by you. The client will then bring the finished product to us for tinting.
Why should opticians stay away from copying Irlen Spectral Filters?
The degree of precision required cannot be "eyeballed," even by the best technician. Many such clients return to us with headaches, discomfort and unsatisfactory performances.
It is a not recommended to copy an Irlen overlay color into glasses.
Human physiology is such that the colors required when "looking through" are quite different than what is required to "look at." It may cause headaches, discomfort and unsatisfactory performances. Obviously, we will not assume any responsibility is such a situation.
