Information for Opticians
Irlen syndrome is a neurologically-based visual 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 some optometrists and ophthalmologists are also certified Irlen practitioners. Selling frames to Irlen clients Frames purchased should allow minimal light to enter the eyes over the top or at the sides. As some clients with Irlen Syndrome are tactile defensive, they find it difficult to tolerate the feel of frames. Please take care to ensure frames are comfortable as well as attractive. Technical issues The Irlen Institute can tint CR39 lenses provided that no anti-glare, anti-UV or anti-scratch treatments were applied. These lenses must be accompanied by a valid prescription. The Irlen Institute can also supply such lenses in a plano or a single vision prescription. In this last case, a valid prescription is required, including a P.D. measurement . In such event, the client will come back to you to have the lenses cut and edged to fit the frame purchased from you. We do not sell frames at our Irlen Centres although a few stock frames can be ordered through the Irlen Institute. If a sturdier lens is required, please contact us for more information. Progressive lenses The Irlen Institute does not provide progressive lenses because of the precise measurements requiring the client to be physically present. If the chosen glasses have a complete frame, please supply the lenses, cut and assembled in the frame. The exception is with rimless or drill-mounted frames. Please supply only the cut lenses. The client will bring the lenses back to you for re-assembly. Wraparound lenses 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 prescription lenses prepared and mounted by you. The client will then bring the finished product to us for tinting. If Plano lenses are required the frame is sent in and the Irlen Institute provides the wrap lenses. Hi Index lenses Please contact us for detailed information about providing Hi-Index lenses that can be tinted. 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. Please do not 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." These incorrectly tinted glasses may cause headaches, discomfort and unsatisfactory performance. Obviously, we will not assume any responsibility in such a situation. |
