Irlen Syndrome often affects depth perception. One outcome of this presents itself with difficulty driving. For me it made it difficult to tell when I had enough time to pass a car on a 2 lane road if another car was approaching. I also tended to come up behind cars too suddenly. In addition I had trouble with parallel parking. And the glare from headlights coming at me on a 2 lane road or coming up behind me on any road seemed like the vehicle had its bright beams on. The headlights were surrounded by a big halo of light.The worst situation was driving on a 2- lane blacktop road at night in the rain. Invariably, when I flicked on my bright beam, I found that I was wrong. After receiving my Irlen tinted lenses I could see the embossed pattern in the headlamps. It was amazing. This mystified me. I, because I wanted to get off the highway, would drive above the speed limit in order to get off the road sooner. After I received my tinted lenses I comfortably obeyed the speed limit. Please comment on your experience with resolution of Irlen Syndrome with regard to driving, It would help many people throughout the world. Take note that 6,000 U.S. teenagers die each year in auto accidents. If up to 14% of the population has Irlen Syndrome then 840 of these victims probably could have been detected in school had there been mandatory screening for Irlen Syndrome. Irlen Syndrome can affect judgement of distances like passing cars and coming up behind other vehicles.
