The real name of Blu-ray is called High Energy Visible Lights, that is, high-energy visible light. Light is an electromagnetic radiation, the possibility of electromagnetic radiation on the human body injury, with the energy, or increase the frequency and strengthen. Such as high energy, high frequency, short wavelength of cosmic rays on the human body is the strongest damage, the frequency of a lower level of ultraviolet light will cause harm to the human eye, and may cause skin cancer.
"Blue light" refers to the most visible part of the visible light, these wavelengths in the 400-500 nm range of light frequency is slightly lower than the UV, is the highest energy in the visible part of the color is blue and purple, so be Commonly known as "blue light".
Blu-ray damage to the human body is now also part of the "early study" - unlike UV damage with millions of patients every year as a case, Blu-ray hazard evidence is also mainly concentrated in the rabbit rabbit monkeys these poor experimental animals.
