LED Blu-ray can be blind: there are ways to solve

Recently, medical experts worry that LED blue light will cause damage to the retina, even blindness. This news has attracted a lot of attention from netizens and a large number of forwarded comments on the Internet, and it has also attracted the attention of light source experts. For a time, anti-Blu-ray glasses are hot on all major e-commerce platforms.

The real name of Blu-ray is called High Energy Visible Lights, which is high-energy visible light. Light is an electromagnetic radiation. The possibility of electromagnetic radiation harming the human body is enhanced by the increase of energy or frequency. For example, cosmic rays with high energy, high frequency and short wavelength are the strongest damage to the human body, and ultraviolet rays with a lower frequency will also cause damage to the human eye and may cause skin cancer.

"Blu-ray" refers to the portion of the visible light that is closest to the ultraviolet light. These wavelengths are slightly lower than the ultraviolet light in the range of 400-500 nm, which is the highest energy part of visible light, and the color is blue and purple, so it is Commonly known as "Blu-ray."

The harm of blue light to the human body is now also an "early study" - unlike the case of ultraviolet damage, which has millions of patients every year, the evidence of blue light is still concentrated on the poor experimental animals of the pika. In this way, in fact, the harm of Blu-ray to people is not confirmed, naturally it will not design a standard Blu-ray protection product. In addition to the lack of evaluation, the way Blu-ray glasses and similar products are protected by separate blue light filtering is not that very appealing.

Whether it is sunlight, light or the light of the display, it is a mixture of different wavelengths and different colors. If we are only eccentrically filtering only blue light, the most direct consequence is color cast. That is to say, your home's carefully selected color saturation, high degree of reduction, ultra-high-definition 4K screen, instantly was plagued by glasses.

To reduce Blu-ray, there is an easier way: to moderately reduce the brightness without hindering reading and viewing. In addition, it is to watch reading on a mobile phone, iPad, computer or TV. The problem is not the blue light, nor the radiation of these common gimmicks. These electronic products are not a big problem in their own right, but their appearance has greatly increased the length of our "reading and watching" time of day.

Whether it's a 1-year-old baby or an adult, convenient new products and mobile Internet give us the opportunity to read, watch videos, chat, play games anywhere, anytime... and these behaviors can make our eyes more tired Increase the likelihood of suffering from related diseases.
