Led blue light may cause blindness. How to solve the harm of blue light

Abstract: Recently, medical experts worry that led blue light will cause damage to the optic membrane, and even blindness. This news has attracted extensive attention and a large number of forwarding comments from friends on the Internet, and has also attracted great attention from light source experts.

recently, medical experts worry that led blue light will cause damage to the visual film, or even blindness. This news has attracted extensive attention and a large number of forwarding comments from friends on the Internet, and has also attracted great attention from light source experts.

the real name of blue light is high energy because of this point: visible lights, that is, high-energy visible light. Light is a kind of electromagnetic radiation, and the possibility of harm to human body caused by electromagnetic radiation increases with the increase of energy, or frequency. For example, cosmic rays with high energy, high frequency and short wavelength are the most harmful to human body. Ultraviolet rays with a lower frequency will also cause damage to human eyes and may cause skin cancer

"blue light" refers to the part of the visible light that is closest to the ultraviolet light and is connected to the angle sensor. The frequency of these wavelengths in the range of 400-500 nm is slightly lower than that of ultraviolet light, which is the part with the highest energy in the visible light. The colors are blue and purple, so it is commonly known as "blue light"

the harm of blue light to human body is still an "early research" - unlike ultraviolet damage, which has millions of patients as cases every year, the evidence of the harm of blue light is still mainly concentrated on the poor experimental animals such as pikas and monkeys. In this way, in fact, the harm of blue light to people has not been confirmed, so standard blue light protection products will not be designed naturally. In addition to the effect that cannot be evaluated, the way that anti blue light glasses and similar products are protected by filtering blue light alone is not so pleasant

whether it's sunlight, light or the light of the display, it's a mixture of different wavelengths and colors. If we only filter blue light eccentrically, the most direct consequence is color deviation. In other words, your carefully selected color saturated, high reduction, ultra-high definition 4K screen will be harmed by glasses in an instant

there is a simpler way to reduce blue light: turn down the brightness moderately without hindering reading and viewing. In addition, even if you watch and read with, iPad, computer or TV, the problem is not Blu ray or radiation, which are common gimmicks. These electronic products themselves have no major problems, but their appearance has greatly increased the time we spend "reading and watching" in a day

no shear experiments are divided into one-way shear experiments and two-way shear experiments. Whether it is a 1-year-old baby or an adult, convenient new products and mobile Internet give us the opportunity to read, watch videos, chat and play games everywhere all the time... And these behaviors themselves will make our eyes more tired and increase the possibility of suffering from related diseases
