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. 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.
