False Claims Mislead About Dyslexia Treatment

The IDA (International Dyslexia Association) filed a non-emergency report with the FDA this month regarding the claims that ChromaGen coloured lenses have been approved to aid in the treatment of Dyslexia.  This is NOT true.  The lenses have been approved only for the following:

FDA Approval of ChromaGen Colored Lenses: According to the Food and Drug Administration (FDA), they cleared ChromaGen’s Reading Aid & Color Discrimination Enhancement, Spectacle Lenses for market for the indications for use as stated below in 2002.  They were not cleared for the treatment or remediation of Dyslexia or other learning disabilities.


  • Prescribed for the correction of refractive ametropia (myopia, hyperopia and astigmatism) in aphakic and not-aphakic persons.
  • Prescribed as a colored filter to aid individuals who experience reading discomfort not related to binocular vision problems or uncorrected refractive error.
  • Prescribed to enhance color discrimination in patients with protan or deutan (red-green) color vision deficiencies
