Mirror image is cause of dyslexia

Guy Ropars and Albert Le Floch of the Université de Rennes 1 in Brittany found dyslexic people had light receptor cells that allowed them to see two ‘mirror versions’ of a letter at one time.

They found a spot in the eye, Maxwell’s spot, was non-symmetrical in one eye and round in the dominant eye. The brain reads signals from the round spot but dyslexics had a round spot in each eye, giving the brain two confusing images.
