According to Dr. Albert Le Floch and Dr Guy Ropars, lack of a dominant eye may be to blame for the onset of Dyslexia. Their explanation states that both eyes working together, but without dominance, create an after image. This after image causes the difficulty
While it is doubtful that this research tells the whole story, it is an interesting find. There is much research that points to visual abnormalities in dyslexics. But the same could be said of phonological abnormalities or spatial difficulties. It is a complicated subject, to say the least. Which is why it is important to use a system that works on all of these areas rather than a single approach.
This research does validate some of the key principles of the Learning Success System. The system has always put a focus on mixed dominance, visual tracking, and proprioceptive exercises which help the brain establish dominance.
