According to Alice Wellborn, a dyslexia expert of some note:
Many years ago, researchers believed that dyslexia was a visual perceptual problem - that it was based in how a person saw letters and words. Now we know for sure, through brain imaging studies, that dyslexia is a problem in the language system of the brain, not the visual system.
Dyslexia is the result of a significant weakness in the phonological processing system, or how a person's brain understands and can use the sound-based reading "code". A dyslexic reader has difficulty cracking that code.
Here are some important facts about dyslexia:
Dyslexia is based in how a person's brain functions. The brain structure is normal - the glitch is in the wiring. Fluent readers use a part of the brain for reading that dyslexic readers do not use. This means that reading remains a slow, laborious process for children and adults with dyslexia.
Dyslexia is not related to a person's level of intelligence. Many children and adults with dyslexia are gifted, highly accomplished, creative people.
However some kinds can be corrected like visual problems. I know a guy with dyslexia who uses very specific, slightly tinted (towards green) lenses in his glasses. I can't remember what else was different about them, but basically they were very personalised and had the effect of slowing down the eye movement over the text. (as in, it forced him to track the lines normally instead of jumping around) Based on chat experience, they made a lot of difference.
