in recent years, reports of blu-ray blinding often appear in the network, television and print media. Many led lights manufacturers are also often used to eliminate the blu-ray as the selling point of product promotion. What is blue light, what is the harm of it, the led lamp's blu-ray have how old? Blu-ray refers to the wavelength is 400 - The light of the 500 nm ( Different wavelengths in different color reflection on the vision, for example - 600 700 nm light is red, 500 - 600 nm light is yellow light, etc. ) 。 ) 。 The shorter the wavelength, the higher the energy, the stronger the penetrating power, the greater the damage to the human eye. Blue light damage to the human eye is mainly including tianjin visual fatigue caused by traffic lights. Lighting test proves that the blu-ray content too high may lead to increased visual fatigue. Second, it affect the physical development of eyes. Animal experiments prove that the blu-ray in mice has the effect of inhibiting myopia, blue light may affect the physical development of the human eye. Third, the long-term work under high light environment may induce macular degeneration. About the dangers of led light, experts point out that ordinary led light source, basic in 450 - the peak spectrum 470 nm range, ordinary light environment illumination is generally not more than 600 lx. In addition, led lighting package outside the led light source. Led TV, mobile phone and computer screen all adopt the backlight or side light mode. Therefore, it can be said that most ordinary manufacturer production led lights and led display screen will not harm the blu-ray, namely blu-ray will not deal damage to the retina. So about the led blue blind rumor is not true.
