Tinted Lenses define success as finding the color that the dyslexic prefers best. This they do 100% of the time. Their success at removing visual problems that make reading difficult is much lower.
See Right Dyslexia Glasses filter out the visible, UV and IR auto-fluorescent wavelengths that are associated with visual problems. The idea is to filter out all wavelengths of light that can cause problems for any individual so that all individuals will have their visual problems removed.
The problem with finding one individualized color for a particular visual dyslexic in the prior art of using tinted lenses is that it is not usual that there is just one color that seems to help. It is true that there might be one color that seems to help most but along the way there are colors that seem to help that are later discarded.
Consider the dyslexic that first prefers color A then color B then color C. Color C is selected as the preferred color and never compared against a combination of C+A or C+B or C+A+B.
Next consider three visual dyslexics where one chooses A, one B, and one C. The See Right Dyslexia Glasses filter out colors A, B and C which means that the dyslexic who preferred A is helped as well as the dyslexic who preferred B as well as the one who preferred C. If the one color assumption were true and that was all the See Right Dyslexia Glasses did, they would have the same low success rate as tinted lenses.
In addition, any combination of A+B+C is also filtered out, which would never be determined where the assumption of a one color answer is assumed.
This is the basic information you need to consider when comparing the See Right Dyslexia Glasses to tinted lenses using the one color theory for one dyslexic.
