Vision Problems NOT the Cause of Dyslexia

Posted Jun 02 2009 4:41pm 1 Comment
A popular myth about dyslexia is that it is a vision problem.  Dyslexia is neurologically based, and has nothing to do with vision.  A child could have acuity problems AND dyslexia, but problems with eyesight do not cause dyslexia.  If your child is having difficulty seeing the board or reading, it is certainly a good idea to have a thorough eye exam.  However, "vision therapy" will not cure dyslexia.  Beware of any doctor who makes that claim.

Another popular myth is that dyslexia and vision are not related. It's true that dyslexia and vision are not generally related as visual dyslexia is only a primary cause of reading difficulties in about 10% of dyslexics.

Neurological differences as indicated by F MRI studies on different areas of the brain show the same types of differences in the visual centers of the brain as they do online but processing areas.

The same types of studies of the difficulties that dyslexics have with background noise have also seen the same types of results with visual noise.

While there are many visual problems that eye Drs. can adequately identify and remediate the problems associated with visual dyslexia are not yet identified are treated successfully in the doctors office.

I guess part of the problem is that many visual dyslexics have 20/20 vision but still experienced visual problems and make reading difficult. Another part of the problem common to many researchers is the idea that all dyslexics are the same.

The reasoning seems to be that when many dyslexics are tested for visual problems and the great majority do not have visual problems the conclusion is drawn that vision is not an issue. This is very unfair to the minority of visual dyslexics that have visual problems that make reading difficult.

When posting on comments made by eye professionals about how dyslexia and vision are not related, I often make the observation that dyslexics statistically have a higher rate of poor depth perception.

I mention that because I sell See Right Dyslexia Glasses that restore normal depth perception to those visual dyslexics with poor depth perception. I am aware that I doctors have limited success with depth perception problems and that the process takes a considerable amount of time. This is in contrast to using my glasses with an instantaneous improvement while they are worn.

If you would consider that the neurological differences associated with visual function could be described as having sensitivity problems with visual noise then eye doctors could properly say that's just not my job because it is neurological.

Before I even mention the mechanism I suggest you do this thought experiment. Imagine a single photon, representative of part of an image, that when traveling through the eye changes its path and both no longer represents the original image and also impinges  on the retina where it should not be and disrupts the proper image.

They accepted view of the eye by doctors does not allow that mechanism to exist. The reality is that there are many different types of autofluorscent proteins located in the eye that are activated by specific wavelengths of light that do in fact follow that mechanism.

Much diabetic research involves measuring autofluorscence ( from proterins) , that exists naturally in the eye and then subtracting it out for experimental purposes.

When you consider that dyslexics have the same structural differences in the visual centers of the brain, are known to have sensitivities to both auditory and visual noise, it is not unreasonable to suspect that those with higher sensitivities to visual noise respond with visual problems that make reading difficult due to visual noise causing autofluorscent proteins.

Certainly vision isn't a general dyslexia concern. I market my visual dyslexia glasses to those visual dyslexics that can describe the visual problems that make reading difficult.

I guess it needs to be said that the group of auto fluorescent proteins in the eye each respond to a specific wavelength of light and so generate a list of wavelengths that can be filtered out at one time to remove the visual noise.

It is also well documented in diabetes research that the amount of autofluorscence can vary from eye to eye which means the visual noise can vary from eye to eye which explains the higher rate of poor depth perception in visual dyslexics.

So while the argument could be made that it is the brain sensitivity to visual noise that causes the visual problems associated with visual dyslexia, I would argue that the location of the cause of the visual noise being located inside the eye makes it a vision problem.
