1, no, but it can impact on people. 2, considering that the quality of mobile phone film is different, it is not recommended to stick the film. Now, as for a lot of mobile phones, the surface of glass is very hard, which can prevent wearing, skidding and scraping, the significance of sticking the film is not great. If the quality is not good, the scratches and the oil are easy to interfere with the eyes." 3, in general, it may be good to eyes without screen protector. First, the occlusion of protective film causes the smaller light get into the eyes, resulting in insufficient light perception of eyes, so the eyes prone to light stimulation and fatigue. Second, if the cell phone film has some quality problems or a lot of scratches on the film due to the use of long time, it will produce a lot of reflected light to interfere. The ciliaris of the eyes are always in a state of tension in a long time, it will be easily damaged. 4, considering that the illuminance of the phone screen itself is relatively low, and then pasting on a layer of mobile phone film will further decline the screen transmittance, it is easier to increase the fatigue of the eyes. For a long time, the lens can not be restored to the normal state of the eye, it will form or aggravate the myopia, it is easy to do harm to vision. 5, so it is right that the mobile phone film will affect the vision. Relevant experts believe that the mobile phone film may reduce the screen transmittance and definition, it is more harmful to eyes to use the mobile phone under the weak light environment for a long time, it is not recommended to stick the mobile phone film. 6, mobile phone film is only the "booster" to harm the eyes, the main reason is the use of mobile phone "in short distance for a long time with eyes", the harm is far more harmful than looking at the computer and close reading and writing.
There is no big impact, because mobile phone film in fact is purely business as a means to make money. Now, the big screen touch screen mobile phones all have the little possibility of scratching the screen after special treatment. Most of the time, it just is a psychological need for consumers, which result in that the display effect is greatly reduced, but also it can increase the eye fatigue, so there is no any effect.
Certainly not. It can prevent the phone from being scratched. There is a film on the screen when you buy the phone. The general film is not bad, it just make the sensitivity of handwriting lower, which can be ignored. Inferior screensavers are sticky, which will corrode the screen
