It will be interesting to see if additional studies corroborate this finding and if the proposed treatment is effective for those suffering from dyslexia. If so, this could be huge for schools to be able to catch and treat dyslexia early before kids struggle and get behind.

Scientists may have found the cause of dyslexia, study says

Researchers from universities in France recently conducted an experiment, published in the Proceedings of the Royal Society B , to determine how the cells in the eyes may affect the brain.

They discovered differences in the shape of spots located in the red, blue and green cones of the eye, which are responsible for color.

For the non-dyslexics, the blue cone had a different shape in each eye - one that was round and another that was more oblong. Analysts say the asymmetry allows the signals in one eye to override the signals in the other, producing a single image in the brain created by the dominant eye.

As for the dyslexic, the blue cones were symmetrical. Scientists believe the identical arrangement produces “mirror” images in both eyes that may confuse the brain. Therefore, there is no dominant eye.

However, researchers say it’s treatable, because there is a preventable, minuscule delay that occurs before the mirror images are sent to the brain.


"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther

The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill
