For me the amazing improvement in depth perception and color depth are reminiscent of what I experienced when I had my CR-39 plastic eyeglass lenses tinted with my Irlen tint. If you wonder what a difference the Irlen tint might make for you or a loved one just go to a store and see for yourself what I mean. Look at a picture on a TV and then observe the fantastic image delivered by a Blu-ray DVD player. Judge for yourself. You might find it noteworthy that I am passionate about seeing more clearly because I lost more than one-quarter of the visual field in my right eye when I was age 19. The good news is that I carry a genetic mutation 11778 that made me a candidate for going blind with LHON (Leber’s Hereditary Neuropathy). The good news is that my vision loss was remarkably minimal compared to what later happened to my mother, Helen Wheaton. She and her sister, Helen Jacob both lost their sight due to Leber’s. Mom’s ophthalmologist was floored to learn that mom was able to mow the lawn because she could sense the contrast between the cut and the uncut grass.
