Educators, Professional scientists, psychologists and many other researchers agree there exists a population who have cognitive difficulty in learning to read, even if no other impairments exist like: seemingly low intelligence, delayed development of the senses or emotional problems.
Dyslexia is a cognitive, language processing issue, which can be divided into two groups: dyseidesia and dysphonesia.
Dyseidetics have poor sight recognition of words. They have to sound out words and read very slowly because it is difficult for them to visualize words, spelling words that look different from what they sound like is a challenge.
Dysphonetics have difficulty sounding out words. They may read at a normal rate, but make many substitution errors.
People who suffer from Dyslexia often have a blend of these and other subtypes of dyslexia.
Unfortunately, optometrists will insist that Dyslexia can be 'cured' with some form of 'corrective' lens. If only the solution was that simple.
Many who have a reading disability, including those who have dyslexia, do develop inefficient eye movements and focusing problems. Therefore, lenses, eye glasses and vision therapy can be prescribed as part of a larger multidisciplinary effort to improve their ability to read and learn but it is not the complete answer.
