GoodNight® is the only eyewear that addresses sleep. It is designed to block almost all the blue light spectrum, which disturbs natural sleep patterns (circadian rhythm). The other filters, which have different purposes, choose to reduce the amount of blue light reaching the eye by between 10% and 40%, which is not enough to help you sleep better.
Absolutely, and even better than standard blue filters because much more blue light is filtered. Given their propensity to induce sleep, it is inadvisable to wear them during daytime activities.
You will feel the full benefits after wearing them for 15 evenings. But many people find an improvement even earlier.
However, those with longstanding 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.
Human nature makes us all different, so GoodNight® cannot always have a uniform effect. Some find that GoodNight® helps them fall asleep quicker; others say that they benefit mainly from a deeper and undisturbed sleep. But the large majority of users will benefit from both advantages.
Yes, especially if they read in the light of low-energy bulbs.
GoodNight® glasses are designed to fit over corrective spectacles. They are thus suitable for every eyesight.
On the contrary, by cutting glare from the screen GoodNight® glasses make viewing more comfortable and prevent tired eyes.
GoodNight® works best after two hours, in phase with the natural circadian rhythm. Although we recommend this period, each individual reacts slightly differently. Perhaps wearing the glasses for a shorter period might work for you.
If you wear the glasses for two hours before going to bed, the GoodNight® effect will be practically the same whether you sleep during the day or at night.
GoodNight® is designed to help you sleep, so you should only wear the glasses for the two hours before you retire.
The glasses have been designed and tested to filter out blue light without really reducing the light intensity. They therefore improve visual comfort without inducing eye fatigue.
Given the sleep-inducing properties of GoodNight® glasses, driving while wearing them is a risk you should avoid, even if you plan to sleep at the end of your journey.
GoodNight glasses are very effective protection from shortwave blue light that disturbs your sleep. However, its special filters are not strong enough to protect your eyes from the sun’s glare.
Wherever your destination, and irrespective of the time difference, you use your GoodNight® glasses the same way. Wear them for two hours before you intend to sleep.
