Eye deformity may be cause of dyslexia: Study

According to a new study, people with dyslexia may not have a dominant eye, which may cause the "mirror effect that disrupts their ability to read", Daily Mail reported.

Close to 700 million people struggle with dyslexia across the globe.

For the study, 60 participants' (only half were dyslexic) eyes were examined. Non-dyslexic people had spots that revealed one eye was dominant over the other. While the spots in each eye found in dyslexics indicated that no eye was dominant.

Not having an eye that is dominant can create confusion in the brain by creating "mirror images". This makes it difficult to read and learn.

"The lack of asymmetry might be the biological and anatomical basis of reading and spelling disabilities," study authors are quoted as saying by the Daily Mail.

Previous research suggests that the medical condition may be inherited genetically, or may have developed at birth.
