The quality of the bought mobile phone film is not up to standard. Nowadays, many mobile phone films are coated with some AF coating, but it is not as uniform as electroplating. What's more, it directly deceives consumers. Therefore, it is best to buy anti-blue film from a company specializing in the production of films, at least with patents, test reports, brands and trademarks.
Anti-blue film can block some blue light and protect eyes, but even if it is pasted, it can't face the mobile phone screen for a long time. It is recommended to take a rest with your eyes.
The blue light protection film is a kind of eye protection film developed for the harm of blue light to eyes. The multi-layer lamination method is used to block the interference and reflection of blue light on the screen, thus weakening the intensity of blue light reaching the retina of the eye, reducing its irritation to the eyes and achieving the purpose of protecting the eyes.
the color is slightly yellow. Put 1 yuan under the anti-blue film and irradiate it with a blue flashlight. No pattern can be seen (if the blue film is removed, there will be a pattern). The main identification method is to use a blue flashlight to check. Generally, a good film will send a blue flashlight.
Blue-light-proof film does not mean that the more blue light is filtered out, the better, because blue light is an important part of the three primary colors in nature, and filtering too much blue light will lead to color distortion and affect vision! Therefore, the anti-blue film must ensure that it does not distort the color while blocking the blue light.
