【National standard for anti-Blue light】

                         YILENS OPTICAL anti-blue ray lenses meet the standard

Recently, the latest national standard against Blue light "GB/T 38120-2019 Blue light protective Film Optical health and light safety application technical requirements" has been officially launched on July 1 this year.If you haven't paid close attention to the new gb, you probably still have a lot of questions in mind: What is blue light?How do you identify the standard anti-blue glasses?

How is blue light good or bad?

Blue light refers to light with a wavelength between 400 and 500 nanometers, which is common in everyday life. All kinds of energy-saving lights, LED lights and incandescent lamps,  flat panel displays, liquid crystal displays, mobile phone screens and other new artificial light sources emit visible light blue light.

It is widely believed that blue light can cause photochemical damage to the eye retina, leading to macular degeneration and even blindness.In this regard, according to the data from the visual health and safety protection laboratory, short-wave blue light with a wavelength of less than 445nm is harmful blue light, which will cause light damage to our eye retina and cause macular degeneration.

What is the new national standard against blue light?

At present, some anti-blue light products in the market cannot meet consumers' demands for health protection, which is more likely to cause health and safety problems.The introduction of the new national standard not only sets a stricter standard for anti-blue ray lens, but also puts forward a more standardized requirement for the industry.

Since the implementation of the new national standard, YILENS OPTICAL immediately sent the lenses with anti-blue ray function to the National glasses product quality supervision and Inspection Center for testing. After quality inspection, YILENS OPTICAL anti-Blue ray lens series all meet the issued national standards.
