Increased Cancer Risk From Using Light During the Few Hours Before Bedtime, According to New Studies
Pepper Pike, OH (ContentDesk) June 19, 2006 -- The May 2006
Journal Cancer Cause Control
contains scientific studies that again warn of the danger of the nighttime use of artificial light.
They confirm many previous studies that conclude that suppression of the hormone melatonin by exposing the eyes to light during the night leads to an increased risk of breast cancer and other cancers as well. Scientists have been issuing this warning since the early 1990s. For some unexplained reason the media have been very slow to make this information known to those with the greatest need to know, namely cancer survivors and those at high risk
because of their genetics. Perhaps the reason is the false belief that there is nothing people can do about it, so why alarm them.
Less well publicized studies by Brainard in the US and Thapan in the UK showed that not all colors of light have the same effect on the pineal gland, the source of melatonin. It is the blue component is white light that causes suppression of melatonin. A study lead by Kayumov in Canada showed that subjects wearing glasses that blocked the blue light continued making melatonin, even though exposed to bright light, just as they had during previous nights when they were held in darkness. To avoid the danger of increased risk of cancer, avoiding light all together, or wearing glasses that block the blue light, for a few hours before bedtime, should become normal practice for everyone, based on these studies. The many cancer related organizations and the media in general need to make this known to the general population.
Close fitting glasses that completely block the light at wavelength less than about 530nm are available on the internet. These are the portions of the spectrum causing melatonin suppression. Searching the internet with key words
cancer low blue lights will locate them. Another solution is to block the blue light at the source by covering it with a filter that absorbs the blue light. Filters for TV and computer screens along with light bulbs with filters can also be found on the internet.In addition to helping fight cancer, melatonin also promotes sleep.
Wearing glasses that block the blue light for a couple of hours before bedtime allows the melatonin to begin flowing. By bedtime there is a good supply.
People report falling sleep very quickly and sleeping more soundly. Two excellent articles in the non-profit Science News Bright Light: Big Cancer
by Ben Harder and Light Impacts by Janet Raloff have recently pointed out the importance of light and how it impacts human health and nature in general..

What Does It Take To Get A Multifocal Contact Lens?
Honestly, what does it take to get into a pair of multifocal contact lenses? I know they're used for correcting the effects of astigmatism and presbyopia. I happen to know a bit about multifocal vision correction in general--and I should. After all, my father is named Benjamin Franklin (no, really) and Benjamin Franklin invented bifocals. But my experience with multifocal contact lenses has been rather limited, despite my best efforts. Even direct questions to my optometrist failed to produce any results.My Life in Technicolor Glasses
I have a long personal history of vision correction.I got my first pair of glasses when I was eight years old. It was a fate I couldn't avoid, with both my parents...

Play It Safe in the Sun--Wear Those Shades!
As you rub in the sunscreen to protect your skin this summer, don't forget sunglasses to protect your eyes. With the thinning ozone layer, it's not just skin cancer you have to worry about. Your eyes are vulnerable to the effects of Ultra Violet (UV) rays as well. This same radiation that damages skin can also increase your risk of developing eye problems, such as cataracts--a clouding of the eye's lens which develops over years. Sunglasses are no longer a simple fashion accessory but a health conscious necessity.
Sunglasses are a vital, and often under-appreciated part of eye care in the outdoor environment. Legend has it that sunglasses originated in China and were created by tinting glass lenses with smoke from open fires. As far back as the fifteenth century, Chinese judges wore these tinted lenses so as not to reveal partiality when examining evidence place before them. However, sunglasses really came into their own during World War II, when fighter pilots made good use of...

Attention Consumers : Irlen Lenses Step Down AS There Are New And Better Dyslexia Glasses In Town
(ContentDesk) April 7, 2006 -- Until recently the most popular dyslexia glasses in the US have been Irlen Tinted Lenses. These were based on the concept that each visual dyslexic's problems were caused by a color unique to that dyslexic and therefore required an expensive personal evaluation to determine that color. A major problem to the consumer with that concept was that because most of the cost involved the evaluation which was received there could not be an effective guarantee. Combine that with a high failure rate and you have a product that is expensive to try with no guarantee of success. The quality standard for success in this method was also low because as soon as a client said this color is better than that one success could be claimed.A different approach and concept was needed .If different colors effected different dyslexics then couldn't it be that the dyslexics were sensitive to several colors and the Irlen Method could only find the color that effected that dyslexic...
