What does blue light do?
Everyone knows that sunglasses protect our eyes against UV radiation. That sunlight also contains blue light radiation, which can also have a negative affect on the health of the eyes, is less well known. Since blue light is emitted also by LED lamps, screens, smartphones and tablets, we expose our eyes to this high-energy light much more frequently than in the past.
In addition, too much blue light radiation, especially before going to bed, can have a negative impact on the quality of our sleep.
