The blue light wavelengths emitted by TV, computer or smartphone screens, as well as by the new generation of low-energy light bulbs, suppress your production of melatonin, the hormone that regulates your sleep patterns.
Blue light is 100 times more active on the light-sensitive receptors in your retina than the white light from traditional light sources, for the same intensity of light.
The high-tech GoodNight® glasses filter and block this high-energy shortwave light. This protection allows your body to resume production of melatonin. And you’ll find that you quickly resume natural sleep as well.
If you are watching TV, working at your computer or reading a book (especially in the light of a low-energy bulb), wear your GoodNight® glasses for a couple of hours before you go to bed. They’re designed to be worn over corrective spectacles, if need be. Two hours is the time it takes for the glasses to have their optimal effect within the natural circadian rhythm for a better night’s sleep.
GoodNight® glasses become really effective after the 15 days or so that it takes to get used to them, even though you will quickly notice the results.
GoodNight® glasses work just as well for people who work at night and sleep by day — simply wear them for a couple of hours before retiring.
They also help you overcome jetlag, however great the time difference. Again, you wear them for two hours before you intend to go to sleep.
Note that GoodNight® glasses are not meant as sunglasses and do not protect your eyes from artificial light in a solarium.
Clean your GoodNight® glasses with a dry cloth. You don’t need any special cleaning agent.

However, those with chronic insomnia who rely on sleeping pills will take a little longer to adapt to their GoodNight® glasses than those whose melatonin production is mainly affected by blue light.
GoodNight® glasses were designed, developed and tested in Switzerland. They are now made in neighboring France by the world-renowned suppliers of eyewear in the French Jura.
