The latest technologies and therapies

Sleeping disorders are a major social issue. Lack of sleep can lead to more serious problems for adolescents as well as adults.

Finding a solution was the task taken up by a Swiss optometrist, Eugene Duvillard, a researcher with a master’s degree in clinical optometry at Philadelphia’s Salus University, which specializes in vision technologies. He has his own practice in Geneva specialized in ocular therapies and is a member of the American Academy of Optometry (www.optiqueduvillard.com).

GoodNight® gets you back to a 100% natural sleep

Concerned by the growing number of patients complaining of sleeping badly, Eugene Duvillard was one of the first to identify the negative effects of the blue light wavelengths produced by TV, computer, tablet and phone screens, and also by low energy LED lamps.

Today scientific studies in this field generally confirm that the short wavelengths of blue light strongly interfere with the natural production cycle of melatonin, the hormone that governs our sleep patterns. This is the cause of many of the sleeping difficulties that people suffer from in the developed world.

LED lights make the problems worse

The situation is getting worse with the widespread use of the new generation of low-energy light bulbs, because they also emit light wavelengths that have a detrimental effect on melatonin production.

The blue light from these bulbs behaves like the light from screens by acting far more strongly on the photosensitive receptors of the retina than light from traditional sources. The sensors in your eye signal your brain to stimulate or suspend your body’s production of melatonin.

Your eye triggers melatonin production

It took years of research followed by tests with patients who had been impressed with the first results. Now Eugene Duvillard has launched GoodNight® glasses that effectively filter out the light wavelengths that disturb your normal circadian rhythm of wakefulness and sleep.

Specialized cells in the eye’s retina return to their duty of telling the body that the light is changing and it’s time to prepare for sleep.

Melatonin: a return to natural sleep

Worn for two hours before you go to bed, GoodNight® glasses allow your body to resume its production of melatonin and return to a natural sleep cycle. You can wear them comfortably outside prescription spectacles or reading glasses.

Melatonin also has an effect against cancer

Increasing research is being done on the effects of light on some forms of cancer through disturbances in the body’s creation of melatonin. (See the references below in “Dangers of lack of sleep”).

A leading specialist in this area is Professor David E. Blask of the Tulane University School of Medicine, Louisiana, and head of his own chrono-neuroendocrine oncology laboratory. With some 250 publications to his credit, his research covers the treatment of some cancers with melatonin as well as the carcinogenic effects of strong urban lighting (see http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4038658/ - Breast Cancer and Circadian Disruption from Electric Lighting in the Modern World).

For years he has been convinced that melatonin could be used in the treatment of some cancers for its antioxidant, immunomodulatory and anti-estrogenic properties or even for its action against the factors of tumor growth.
