Description

  The present invention relates to a display protective film, and more particularly to a blue light cut display protective film.

  A display is often used for various electronic devices, but a large amount of blue light may be emitted in order to generate different colors and brightness. Studies have shown that excessive blue light entering the eye can generate large amounts of radicals that can cause cataracts and even cause degeneration of the macula. In addition, damage to the eyeball caused by blue light gradually accumulates and may be further exacerbated.

  Watching the display for a long time is an act of damaging the eyeball. It is said to be a kind of civilization disease because more people hurt their eyes when tablets and smartphones are used in large quantities.

  In many cases, the display is protected by a display protective film so that the display is not scratched or damaged. This type of display protective film is a transparent film that does not interfere with the image on the display screen and only prevents damage and damage. Although there was a slight blue light cut effect, it was never enough to protect the user's eyes.

Registered Utility Model No. 3183062
