Why is blue light dangerous?
Blue light are non-visible light waves, just like UV light or infrared rays. The problem with light waves: The shorter wavelengths, the more harmful they are to our eyes. Blue light is shorter wavelength than the “visible light“ through which we can see the world in the colors we are accustomed to, and can trigger eye diseases, concentration and sleep disorders or headaches. Yet most of it is emitted by our screens such as computers, smartphones or televisions.
