American Optometric Association 2005

Statement on Dyslexia And Vision Updated in 2009

 

 

 

While I still try to remove See Right Dyslexia Glasses from being associated with tinted lenses ( read compare to tinted lenses ), when the AOA talks about more research being needed on the visual associations with dyslexia and uses the term tinted lenses, the See Right Dyslexia Glasses should be included.

When fMRI studies conclude that there is a visual component to dyslexia and the AOA  changes its position from dyslexia and vision are not related to needing more research, dyslexia web sites that state that dyslexia and vision are not related are using old research that has been refuted by the same source they used.

ST. LOUIS, Mo., March 2005 — An ongoing controversy over whether tinted lenses or filters might help people who have learning disabilities associated with dyslexia has again surfaced in early 2005.

An article in the Wall Street Journal in March points out a recent marketing push by some eye doctors who charge up to $2,000 for diagnostic tests using colored filters for patients with dyslexia, a method that some eye experts say is based on dubious science.

But an official position paper from the American Optometric Association (AOA) based in St. Louis says that some "undetected vision problems may be a factor in individuals who exhibit the symptoms" of a syndrome defined by psychologist Helen Irlen as a connection between dyslexia and vision.

Vision problems are a frequent factor in reading difficulties," the AOA's position paper says. "Ignoring the role of vision or inadequately evaluating the vision of individuals with reading problems is a disservice which may prevent the person from receiving appropriate care."

The AOA says further research is needed, based on reviews of scientific literature showing mixed results regarding the effectiveness of tinted lenses as an aid for people who have reading difficulties associated with dyslexia.

While in 2005 the AOA said that more research is needed , something obviously changed by 2009. The first change is it is now a joint statement with the pediatricians and the subject has changed from Vision and Dyslexia not being related , to Vision and Learning Disabilities not being related.

In a bizarre turn of events, claims of being able to cure all learning disabilities appeared with no scientific backing and were suggesting expensive treatments based on vision.

Helen Irlen began saying that her tinted glasses also helped ADHD, Autism and even good readers learn better. Many Vision Therapy doctors also jumped on the band wagon and started to claim Vision Therapy was the answer to all learning disabilities .

As an individual I also believe such snake oil claims have to be extinguished . As a scientist I would have proof read the statement to remove a few things such as claiming that because the studies done were of such low quality the opposite conclusion could be considered proven. I know that is tempting to say but it really isn't true. It is unscientific to conclude that poor data can be used to draw any conclusions even the opposite .

New Excerpt from 2009 statement about Irlen Lenses

Tinted lenses and filters have been suggested to treat visual perceptual dysfunction that leads to visual distortion caused by sensitivities to particular wavelengths of light but not to treat language-based dyslexia .97 Scrutiny of published study results that advocated the use of these therapies to treat dyslexia have shown serious flaws in their methods and have not been sufficiently well controlled to support this assertion. 30,70,84,85,88 There have also been many inconsistencies in the results, 89,98,99 with some studies showing some partial positive results 100–106 and others showing negative results. 84,86,90–94 The method used to select the lens or filter color has been highly variable,89,104,106 the color selection has also shown considerable variability, 104 and the test-retest consistency has been poor .107 Many of the studies that have been cited as proof of Irlen-lens efficiency have actually been inconclusive after deeper analysis.  The evidence does not support the effectiveness of tinted lenses and tinted filters in these patients because of the weaknesses in methodology and statistics, variability in techniques in the trials, and the largely negative results .8,30,45,70,76,83–94,10

I chose the name See Right Dyslexia Glasses with no intent to suggest that they were effective for dyslexia but because the more apt name of See Right Visual Dyslexia Glasses seemed too long.

"(For Irlen Lenses )The evidence does not support the effectiveness of tinted lenses and tinted filters in these patients because of the weaknesses in methodology and statistics, variability in techniques in the trials, and the largely negative results"

 

Point by point about the differences with See Right Dyslexia Glasses

1.(Weaknesses in methodology and statistics) These most likely refer to screening techniques and the low standard of success.  At times it has been reported that Irlen screeners have had a 50% quota to fill regardless of the clients needs. Defining success when 1 color is better than another has little ability to predict whether the reading problem has been addressed.

See Right Dyslexia Glasses are marketed to those visual dyslexics that can describe a visual problem that makes reading difficult. People are unlikely to describe visual problems that make reading difficult if they do not have those problems. Successful removal of those visual problems normally increase reading speed ,accuracy and comprehension. A policy of having a money back guarantee for any reason removes financial risk.

2.( Variability in techniques in the trials)  By developing a universal visual dyslexia filter ,See Right Dyslexia Glasses, the only technique involved is to put on the glasses and report if your described visual problems have gone away.

3. ( Largely negative results)  Notice that even with inferior methodology and variability in techniques it is implied that Irlen lenses do have some success.

See Right Dyslexia Glasses use self identification of visual dyslexia by including all who can describe the visual problems that make reading difficult and remove those visual problems almost 100% of the time.
