Irlen Syndrome often affects depth of field perception. One outcome of this presents itself with difficulties driving. For me, it made it difficult to tell when I had enough time to pass a vehicle on a 2 lane road when another vehicle was coming at me. I also tended to come up behind a vehicle too suddenly. In addition, I had trouble with parallel parking. And then aside from this there is the trouble with glare. This happened with cars coming at me on a 2 lane road or coming up behind me on any road. It always seemed that the vehicle had its bright beams on, but when I flicked on my bright beams I always found out that I was wrong. This mystified me. When I received my tinted Irlen filter lenses this all ended.

If you have a strong attraction for writing or printing on a certain color of paper it is most likely a clue that you have Irlen Syndrome. I always preferred yellow legal pads or sometimes pink (but I was hesitant to use pink because I thought that might seem odd for a guy to use). When I used these colors the color of the page no longer tried to wrap around what I was trying to read.
