Long-term foreign studies have shown that long-term exposure to blue light can cause eye spot diseases. Therefore, the concept of anti-blue light is proposed. However, there is no exact data on how much blue light and how long the exposure will cause damage. “Blue light panic”, but anti-blue light is still necessary, after all, it is really harmful to the eyes, prevention is greater than cure.
In recent years, various anti-blue light products have appeared on the market, such as anti-blue light glasses, anti-blue light mobile phone film, etc., but the relevant standards are not perfect.
Although we don’t need to talk about the blue-ray color change, everyone would like to know whether the anti-blue-light mobile phone film is useful. Here, Mr. An will tell you a cruel fact: the anti-blue-light mobile phone film is really useless.
