Network transmission of black lights is easy to lose sight of mobile phones
Net transmission: After turning off the light, the mobile phone brightens the screen and causes “eye cancer.” According to this “warning” on the Internet, getting used to sliding the phone before going to bed will cause a big problem.

When people watch them at close range, high energy can directly shine into the eyes, directly harming the macular parts of the eyes, causing macular parts, and causing people’s vision to deteriorate rapidly.Top) Particularly irreversible macular disease.
In addition, looking at the mobile phone after the light is turned off, not only the macular is expected to cause dry eye in the early stage, but severe cases will cause cataracts to report early.

However, there is no causal relationship between turning off the light and watching the mobile phone and causing eye macular disease, including causing myopia, and there is currently no large amount of relevant scientific data to confirm.
In order to avoid “eye fatigue”, experts suggest that when people look at mobile phones and tablets, even if the headlights are turned off, it is best to turn on a small background light, such as a night light, small wall light, etc., to reduce the irritation of the eyes by bright light.
