Glasses that Block Blue Light Help People with ADHD Sleep Better

University Heights, OH (PRWEB) January 30, 2013

Adults with Attention Deficit Hyperactivity Disorder (ADHD) and insomnia experienced significant improvement in measurement of overall sleep quality by the use of glasses that block blue light according to Dr. Fargason, author of a paper in the journal ChronoPhysiology Therapy. “Compared to baseline, the intervention resulted in significant improvement in global PSQI (Pittsburg Sleep Quality Index) scores, PSQI subcomponent scores , and sleep diary measures of morning refreshment after sleep (P=0.0377) and nighttime awakenings (P=0.015). Global PSQI scores fell from 11.15 to 4.54, dropping below the cut-off score for clinical insomnia“ wrote Dr. Fargason.

All of the 24 people (ages 21 – 76, mean age 43.9 years) began the three-month study but only 14 completed the study. This is not surprising in light of the nature of attention deficit hyperactivity disorder according to Dr. Richard Hansler, who led the group at John Carroll University that developed the glasses in 2005. He further commented “Use of lightbulbs that eliminate blue light and filters for TV, computer screens and for phones, might be a way of achieving higher compliance in future tests. Many people who do not normally wear glasses may find it difficult to wear them in the evening”. Of the 14 subjects that completed the test, the 7 with the latest bedtime experienced an advance to an earlier hour of their bedtime of an average of 43 minutes.

The blue light blocking glasses for this study were donated by Photonic Developments that operates a website where these glasses may be purchased. The site also offers light bulbs that eliminate blue light and filters for TV and computer screens and for iPads and iPhones. These products were developed in 2005 in the Lighting Innovations Institute at John Carroll University. The science behind these products is described in books by Dr. Richard Hansler (part owner of Photonic Developments LLC) “Great Sleep! Reduced Cancer!” and “Heroes of cancer Prevention Research” available from Amazon as paperback books or as Kindle books.
