Is there a film for cell phone coating? Membrane junction cell phone nanoprotection and traditional film what is the difference?

Mobile phone coating is just rubbing the flow of film, the surface of the phone screen is just the formation of nano-structured protective layer, rather than like the traditional film is very intuitive to see a thick layer of film affixed to the cell phone screen, in fact, the correct call should be called cell phone nano-protection; film junction cell phone nano-protection is the use of nano-blue light-blocking technology, to protect the cell phone at the same time more importantly is to protect the people's eyes. Play a double protection effect, scientific evidence of the traditional film without a little protection of the scientific basis for cell phone fall, but with the increase in the number of cell phone features, the frequency of use of the growth of a large number of facts to prove that the use of cell phone film is the first killer of eye health.
