Blue light is an important part of visible light. Naturally, there is no single white light. When blue light is mixed with green light and red light, it shows white light. In the era of smart phones, people spend more time staring at the screen of mobile phones. However, mobile phone screens, LEDs, and computer screen lights all generate a lot of blue light, which will cause harm to people's eyes and hands, and will stimulate brown pigmentation and let the skin Producing macula and freckles will deepen the degree of myopia in the eyes, causing visual fatigue, and is also not conducive to normal sleep.

　　The anti-blue light mobile phone film, which is developed based on reducing the damage of blue light to humans, is eyes screen protector. The blue light mobile phone film adopts blue light blocking technology to absorb and transform blue light, thereby effectively blocking blue light. By absorbing and transforming the blue light emitted by the light source of the mobile phone, the anti-blue light protection film can greatly reduce the stimulation of the blue light to the eyes and control the deepening of myopia; in addition to preventing myopia, the blue light protective film can also prevent ultraviolet rays by absorbing and transforming ultraviolet rays. The resulting dry skin causes problems such as skin spots and chloasma. At the same time, the AF coating is attached to the surface of the film to make the touch and hardness of the mobile phone film perfectly combined.

　　The most direct way to identify the anti-blue light mobile phone film is to directly detect it on the spot with a blue light test light. Because the anti-blue film can effectively filter and block the blue light emitted by the background light source of the mobile phone. The production of anti-Blu-ray mobile phone film has strict implementation standards, and it is necessary to pass the certification of professional institutions to be circulated in the market. Therefore, when selecting an anti-blue film, it is necessary to check whether it has blue light effect monitoring by a third party.
