Sleep Glasses: good or bad concept?
Rest glasses, anti-blue light , driving glasses , every frame now seems to have its uses. And another type of glasses is appearing: the Sleep Glasses ! But what can they be used for? Should we start to wear, and therefore create glasses to sleep? Not quite. We'll explain.
Sleep Glasses: simple anti-blue light glasses?
First of all, we can note that this concept of Sleep Glasses does not yet offer a French translation. We could give it a try, offering sleep glasses , or night glasses , but those terms would be, perhaps, slightly incorrect.

These are actually anti-blue light glasses, but calibrated to protect eyes when the light is at its lowest. In other words, when you offer a pair of glasses equipped with anti-blue light lenses , it is in particular to reduce the harmful effects that the latter can cause. These glasses are also systematically offered to people who work on screens.
The difference is above all the level of protection , which will be adapted to the ambient light when the we are getting ready to go to sleep, for example. These glasses would also protect the eyes when waking up in the middle of the night. Indeed, who has not experienced difficulties falling asleep again after getting up to go to the toilet or the bathroom? The light, contrasting sharply with the restful ambience of the night, would mistakenly indicate to the brain that it is time to get up.

These glasses are therefore intended to block more light in order to recreate a environment more conducive to sleep.
A really effective concept?
So, wearing Sleep Glasses before going to sleep, or when you get up during the night, does it work?
Some media, like New York Magazine , or CNN , have looked into the question. The former remain very skeptical, criticizing the yellow or red hues that make wearing glasses unpleasant. Their effectiveness is also put to the test.

Certainly, if most scientists recognize the impact of blue light on sleep (especially because it blocks the production of melatonin , the sleep hormone), many also point to the fact that many other factors can disturb it.
Thus, any professional or personal activity, the stress and many other things can be the cause of difficulties.

Others are more laudatory and highlight the need, in a society hyper-consuming screens of all kinds, to protect oneself as much as possible. It is not always easy to stop facing the screens several hours before going to sleep. But that's another debate.
So, the Sleep Glasses, good or bad concept, according to you?
