Blue Cut

Concept

Blue light is part of  visible light. Both daylight and electronic screens emit blue light. The wavelength of blue light is around 400 to 500 nm. The blue light has  shorter wavelength and higher energy. So that blue light  can directly penetrate the eyes to reach the retina. That may cause macular degeneration. As we know melatonin is an important hormone that affects sleep. It is also to promote sleep and regulate jet lag. However, blue light will inhibits the secretion of melatonin.
