University Heights, OH (PRWEB) March 06, 2012
A recently published study involving more than 30,000 patients found that those who received prescriptions for sleeping pills had a 3.5 times increased risk of death compared to patients for whom sleeping pills were not prescribed. There is a large body of evidence that exposing the eyes to light, especially light with a large amount of blue component, suppresses the production of the sleep hormone, melatonin. This is believed to explain the epidemic of sleep problems. LowBlueLights that do not produce the blue rays responsible for melatonin suppression and eyeglasses that block blue light have been available on the internet since 2005 at http://www.LowBlueLights.com.
While melatonin pills may be relatively safe compared to pills like Ambien or Lunesta, they have not proven to be very effective in double blind studies. Prior to Edison’s great invention, the human body was capable of maximizing melatonin production for 11 or 12 hours.. Now, because of exposure to light in the hours before bedtime, most Americans only produce melatonin for 7 or 8 hours a night. This not only makes sleep more difficult but increases the risk for breast, colon and prostate cancer, heart disease and diabetes. Doctors Brainard and Skeen in independent studies found that it is blue light that is the main culprit in suppressing melatonin. Dr. Kayumov (2005) found that subjects working a simulated night shift under bright lights made almost no melatonin. However, when wearing goggles that blocked blue light they made melatonin just as they had on a previous night spent in darkness.
In 2005, scientists at John Carroll University developed light bulbs that don’t make blue light and eyeglasses that block it. A double blind study found that using the special glasses allowed subjects with sleep problems to fall asleep more quickly and report more restful sleep than when using placebo glasses that did not block the blue rays. This story will be presented next week in Washington DC at a conference on Lighting for Older People sponsored by the Illumination Engineering Society of North America.
A spin-off company Photonic Developments LLC was formed to sell the light bulbs and eyeglasses on the internet. Filters that block blue light are also available for TV and computer screens including iPads. More than 6000 satisfied customers have purchased these products with a money back guarantee that their money will be refunded if the glasses to not improve their sleep. About 90% find they work.
