University Heights,OH (PRWEB) July 31, 2013 -- The announcement this month of filters for large screen TV (up to 58” diagonal).means many more people will be able to sleep well. Recent studies at the University of Besel (1) have shown that exposing the eyes to light, especially blue light, during the hours before bedtime can suppress the production of melatonin by the pineal gland. This makes it difficult to fall asleep and sleep is not as restful according to Dr. Richard Hansler, author of “Great Sleep! Reduced Cancer!” Modern electronic devices produce a larger fraction of blue light than the earlier light sources according to Dr. Hansler. The addition of the filters for large screen TV and computers completes the line-up of filters, starting with filters for iPads and other tablets and many phones including the iPhones and smart phones.
Many of http://www.lowbluelight.com customers make use of amber glasses that block blue light. They wear them starting in the early evening. This means that by bedtime they will have a large supply of melatonin in their bloodstream. This makes it easy to fall asleep quickly and deep, restorative sleep will be reached more quickly and persist for a longer time. This has been demonstrated in studies at Harvard (2) and at the University of Basel (1). Actually, what was measured was the delay in these sleeps parameters as a result of exposure to the blue rays coming from ordinary household lamps.
For those who don’t like wearing amber glasses in the evening, there are light bulbs that don’t make blue light. Their use, combined with the use of filters for TV and computer screens, including iPads and iPhones solves the problem. This is a more realistic plan, now that the large screen filters are available. To order filters for large screens all that is needed is to measure the height and width of the screen and a filter will be custom cut to fit perfectly. The same is true for tablet and iPhone filters that will also be custom cut for a perfect fit
Thousands of people have purchased products that help them sleep better with a money back guarantee on the glasses that their money will be returned if the glasses do not improve their sleep. About 90% find they help. Please call or email with questions to Dr. Hansler 216 397 1657 or rhansler(at)jcu.edu...
