“Hey everybody, it’s Dr. Sam. I want to talk today about dyslexia.
About 1/5 people globally have been diagnosed with dyslexia. Some people experience a mild form where other people can experience an extreme form. Dyslexia is a problem with manipulating and decoding language. There was just a study that came out at the University of Rennes which connected our eyes to dyslexia. Here’s what they found:
In the macula, which is at the back of the eye, we have cones that allow us to see color in detail. People without dyslexia have asymmetrical cellular patterns between the maculas, so this creates a dominance in one of the eyes, which helps the processing of information. In this study, they found that people with dyslexia have identical cellular patterns in the macula, which means they cannot distinguish patterns easily. For example, when they see mirror images, they can get very confused by them. So if they see the lower case B and lower case D, there can be a lot of confusion. The researchers argue that because there is no eye dominance, people get confused in terms of processing information.
I’ve been working with dyslexia for many, many years, and I have seen the connection between our eyes and brain affect learning.”
