What do you mean by video HD blue glasses and anti-blue glasses? Video watching blue light, mobile phone and anti-blue film?

You misunderstood, these are two concepts. Let's start with Blu-ray video. Blu-ray refers to a newer optical disc carrier than DVD. There are two specifications on the market, 25G and 50G. Compared with the 4.7GB capacity of the previous generation DVD, this is a qualitative leap. With large capacity, the film can be stored with higher definition. A 90-minute 4K HD movie can be stored on a 50GB Blu-ray disc, and it can carry nearly 10 multi-channel tracks. So blue light refers to a film source with a resolution above 1080P. Let's talk about anti-blue glasses and film. This is because the wavelength of blue visible light in the sun is harmful to people's vision. Therefore, most sunglasses are plated with blue band filter, so many film manufacturers steal the concept to use on mobile phone film. In fact, the use of blue film on mobile phones will cause color deviation, which deviates from the original intention of mobile phone design for color requirements. Popularize science, the light on the screen of mobile phone is not enough to hurt eyes, but the light around mobile phone is harmful to eyes.
