Devices, Not Drugs: Orange Glasses

Great Sleep! Reduced Cancer!: A Scientific Approach to Great Sleep and Reduced Cancer Risk by Richard L. Hansler

In 2001 it was discovered that it is only the blue component in ordinary white light that causes melatonin suppression.

Melatonin is the hormone that promotes sleep and is a powerful cancer fighter. This book traces the story of how research with animals and humans has demonstrated the health benefits of long periods of darkness that maximize melatonin.

By blocking just the blue light a condition of “virtual darkness” allows enjoyment of normal evening activities while maximizing melatonin flow. The benefits go far beyond better sleep and reducing cancer risk. They include helping to avoid postpartum depression, improving symptoms of ADHD, and helping to stabilize mood in patients with bipolar disorder.

Light and our Lives November 25, 2008
By Rebecca E. Hutchins

As a behavioral optometrist who has long been fascinated by the non-visual portion of the optic nerve, and who recently learned about melanopsin and its implications, this book was meant for me to read. It has an incredible amount of information not readily available on the effects of light at night on our health. The author worked for 40-some years in the lighting industry, and is now concerned enough about the implications of light in insomnia and cancer that he is attempting to find a way to address some of the issues with the use of blue-blocking lenses. I did purchase two pair from the website to compare with those that we use in our office, and found the tint a little hard to handle personally, but I think the topic is a timely and important one, and it is well-handled in this book. I am beginning to believe that Light Pollution and Light at Night may be almost as big an issue to our survival as Global Warming.

Blue light, melatonin, quality of sleep and antioxidant properties April 18, 2012
By J. Duncan

Interesting info on light, the blue spectrum in particular, and how it affects (delays) the start of melatonin production, which affects the onset of sleep. Contains several ideas on how to reduce exposure to blue light, at what times you should consider this, and how even slight exposures late at night (or during the night) can still interfere. UVEX glasses are a cost-effective way to start.

Not sure how - but it works March 24, 2013

Dr. Oz promoted this on his television show. I bought the book and the glasses. I am amazed but if you remember to use them (especially if you are on the computer at night) the technologies works. I get drowsy faster and when I go to bed I fall asleep more quickly. I am a believer.
