An article in the Telegraph suggests that it can.
A duo of French scientists say they may have found a physiological cause for dyslexia hidden in tiny light-receptor cells in the human eye which can apparently be righted.
. . .
In the new study, Ropars and colleague Albert le Floch spotted a major difference between the arrangement of cones between the eyes of dyslexic and non-dyslexic people enrolled in an experiment.
In non-dyslexic people, the blue cone-free spot in one eye – the dominant one, was round and in the other eye unevenly shaped.
In dyslexic people, both eyes have the same, round spot, which translates into neither eye being dominant, they found.
“The lack of asymmetry might be the biological and anatomical basis of reading and spelling disabilities,” said the study authors.
Dyslexic people make so-called “mirror errors” in reading, for example confusing the letters “b” and “d”.
“For dyslexic students their two eyes are equivalent and their brain has to successively rely on the two slightly different versions of a given visual scene,” the duo added.
The team used an LED lamp, flashing so fast that it is invisible to the naked eye, to “cancel” one of the images in the brains of dyslexic trial participants while reading.
In initial experiments, dyslexic study participants called it the “magic lamp,” said Ropars, but further tests are required to confirm the technique really works.

That’s potentially a very important discovery. Dyslexia affects about one in ten people. If it can be treated, or nullified, those people would have a far easier time learning at school, and working in their chosen profession. It would revolutionize their lives.
I hope funding will be found to push this research further forward. It might impact hundreds of millions of people.
