In our daily life, always meet all kinds of all kinds of light emitting devices, such as television screens, the phone's screen, flat screen, fluorescent lamp, and a variety of all kinds of digital products. Visible light emitted from the devices contain harmful blue light. So, blue is almost ubiquitous, unable to escape. How much for blu-ray you know? We know that the human eye can perceive the wavelength of the electromagnetic wave is between 380 nm to 760 nm, and blue clearance is between the wavelength of 400 nm to 500 nm combination part of visible light. Energy the highest part of the blue light is visible light, while harmful blue light said between wavelength at 415 nm to 455 nm blue light, and this kind of harmful blue light can be directly through the crystal direct fundus retina, and the photochemical irreversible damage to the retina. Blue light is we can not ignore to the harm of human body is an important problem. Can accentuate the blue light in the eyes of macular area increased the amount of toxin, causing the macular disease. After the blu-ray intake fundus focus, focus is not on the retina, but falls in between the retina and the lens, thus increasing the light in the eye focus distance color, can cause blurred vision, fatigue, serious even can cause the VDT syndrome. As the growth of the age, the body of the lens itself is gradually yellow, this helps to filter the blu-ray, but after cataract surgery patients lose these natural barrier. Harmful blue light to the retina, leading to postoperative retinal damage. Because the blue light has high energy, so it is in the air in the risk of scattering is bigger, this is the main cause of the anti. Blu-ray will suppress the secretion of melatonin, disturb our sleep, which can lead to insomnia, serious impact on our health. It is understood that in 63. 5% of Internet users have a similar vision, dry glasses, sleep disorder, cataracts, and even blindness and other eye diseases, sin the culprit is the blue light. And the world health organization WHO eye institute has published, each year more than 30000 people worldwide blindness caused by blue light radiation. This is a very horrible Numbers, but many of us don't know. Blue for the harm of children, children under the age of 12 to blue light radiation is almost zero resistance, once the juvenile macular degeneration induced is irreversible damage. Say so many, you still despise the harm of blue? For ourselves, for the sake of your family's health, we must take seriously the dangers of blu-ray. In our daily life, although almost always has to deal with a blue light, we can't avoid, but at home we can take corresponding measures. Especially we almost every household appliances necessary - — The TV, we should attach importance to. Along with the development of science and technology, and now the TV market is flowers, phyletic and various, but many are fake fish dragon, in this part the blu-ray are directly ignored. Many ordinary TV blue peak is about 450 nm, already mentioned above, the peak of 450 nm was belong to the scope of harmful blue light. Maybe a lot of people think that the blue light is easy, a membrane can be filtered out, but in fact the paster blu-ray prevention can only reduce 30% of harmful blue light, color and serious, chicken ribs. So, want to be exempted from TV blue light to our human body damage, is not opportunistic. We need to know, the TV are highlighted in the blue LED lights, as a general backlighting, the lights bead projected out of the blue light projected on to yellow phosphor white light, but the white light contains a large amount of harmful blue light. So we should start from LED lamp bead, choose those wavelengths outside harmful blue light bead chip, so did both avoid harmful blue light, does not affect the normal color of blue light. In order to the health of our eyes, the blue light is really important. So from now on, we should attach importance to the blu-ray invisible harm, whether for ourselves, or for the sake of our next generation, we must have the consciousness of the blu-ray, first for blu-ray we want to have a sense of awe, there shall be no contempt. Don't let harmful blue light damage our eyes!
