This problem. It is better to stick film, screen without film is easy to be stained with dust and difficult to clean up.You can buy a set of cleaning kit with film on the internet, which is very cheap, and you can stick by yourself.
No, it is ridiculous to say that the film is radiation?protection. What film can prevent light radiation? Unless the lead metal. What do you still look at? Ordinary film not only can not reduce radiation, instead, the film itself is plastic synthetic product which is radioactive. General film is mainly used for protecting the screen, preventing scratches and dust, but affecting the appearance. And now there are many hard screen which is not necessary to stick film. You can check your screen to see whether it is hard or soft, namely is there water wave when you pressing the screen, if there is water wave, it is soft, which can either stick film or not, but the hard screen is not necessary to stick film.
It can not be generalized, which should depend on individual demand. View from the visual effect, there are mainly two kinds of computer screen films at present: One is high-definition film, with which the screen turns to be more delicate. but it will increase the light reflection, which will lead to visual disturbance when used in high-lighted environment. The other is anti-reflective dull polished film, which is visually not very delicate, but enable people clearly see the screen in bright environment. So people with visual improvement needs can choose the corresponding film. From the perspective of screen protection, computer film has certain abrasion-resistant hardness, which has physical protective effect on the screen. So it is recommended to stick film for computers used in dusty environment or whose screen is often wiped .
