Blue Light or High-energy Visible Light (HEV) is one of the seven types of rainbow spectrum, consisting of purple, blue, green, yellow, and red. We see the sky is blue because of this light itself. Blue light has a wavelength of about 400-500 nm, the shortest wave length. Most Power In addition to being in the sun, it is also available in man-made artifacts.
Blue light is used in digital devices to increase the brightness and clarity of the screen. Although the blue light is synthesized, it is small compared to the light emitted directly from the sun. However, the use of these digital devices often for many years can directly affect the eyes. Risk of disease as follows.
Harvard University Research Experimented by comparing the effects of blue light exposure to green light with a wavelength of light after a single blue light for 6 and a half hours, melatonin hormones that regulate the watch life. Blocked by blue light. And the change in the life of the test subjects in the green light ever doubled.
