Here’s an excerpt from the Abstract:
Learning disabilities are complex problems that require complex solutions. Early recognition and referral to qualified educational professionals for evidence based evaluations and treatments seem necessary to achieve the best possible outcome. Most experts believe that dyslexia is a language based disorder. Vision problems can interfere with the process of learning; however, vision problems are not the cause of primary dyslexia or learning disabilities. Scientific evidence does not support the efficacy of eye exercises, behavioral vision therapy, or special tinted filters or lenses for improving the long-term educational performance in these complex pediatric neurocognitive conditions. Diagnostic and treatment approaches that lack scientific evidence of efficacy, including eye exercises, behavioral vision therapy, or special tinted filters or lenses, are not endorsed and should not be recommended.
This speaks to the importance and necessity of providing parents with information about what treatments and interventions are supported by research. There is quite a bit of misinformation out there and it may seem overwhelming for parents to try to tease apart what is good for their kids. As clinicians , It is our job to help parents by stressing the importance of only using treatments that have been found to be effective through research. Many of these so-called treatments that have been found to not be effective are very costly, it is a disservice to allow parents to spend valuable resources (time, money, energy) on such treatments.
