French scientists discovered a physiological difference between the eyes of those who have dyslexia and those who don’t. It’s all about the fovea, the center of a region, which is dominated by cones. This cones are also responsible for color perception.
We all have a dominant eye as we have a dominant hand which has more neural connections to the brain. The non-dyslexic person have the arrangement of the cones asymmetrical, while the arrangement of the cones at dyslexic person is symmetrical. People with dyslexia have a round hole at the both eyes. That’s why dyslexic people, when they are looking at a page, their eyes create a mirror effect. They can’t distinguish a “b” from a “d” or an “s” from a “z”. If dyslexia does come down to some misarranged light-receptors in the eye, anyone can detect it with an eye exam. In this study, scientists used an LED lamp that blinks faster than the human eye, so the eye can cancel one of the mirror images. The dyslexic people who volunteered in this study confirmed that the LED lamp is magical.
