Mistakes in preventing blue light

1.What is blue light? Visible light with wavelengths between 400nm-500nm is called blue light;

2. Should blue light be completely blocked? No, only short wave blue light with wavelengths between 400 and 450 nanometers has the greatest harm to the retina, and can increase the amount of toxins in the macular area of the eye. It is usually recommended to have long-term exposure to strong blue light for no more than 2 hours;

3. The misconception of using traditional blue light pens to detect blue light lenses: Blue light pens cannot detect blue light lenses and require professional props, as the wavelength emitted by blue light pens is usually 405nm. They only use the principle that the wavelength is shorter than the UV absorption value of the lens, causing the illusion that blue light is completely blocked, but in reality, they do not.

There are three forms of anti blue light:

1. Substrate absorption: The anti blue light factor is added to the lens substrate to absorb harmful blue light in daily life, achieving the protective purpose of blocking blue light.

2. Film reflection: The surface of the lens is coated with a film to reflect harmful blue light, achieving the protective purpose of blocking blue light.

3. Substrate absorption+film reflection: This technology combines the advantages of the first two technologies, working together to provide dual protection. This technology is mainly applied to lens anti blue light glasses.Anti blue light glasses can effectively reduce the sustained damage of blue light to the eyes. Through comparative testing with a portable spectral analyzer, the intensity of blue light emitted by mobile phone screens is effectively suppressed after using anti blue light glasses, reducing the harm of harmful blue light to the eyes.

The troubles of blue light lenses

Due to the issue of UV index, traditional anti blue light lenses usually appear yellow, which has a significant impact on the color of the scenery, especially for some designers, printing workers, and other professionals who are very sensitive to color Therefore, Eagle Industrial has focused on introducing groundless anti blue light lenses, which will pose a huge disruptive challenge to traditional blue light.
