Recently, #手机贴膜智商税# has become a hot search, sparking heated discussions among netizens. Some people say that phone screen protectors are a waste of money and they never use them; others say that phone screen protectors can protect the screen and are not a waste of money. So, do phone screen protectors really need to be used? What are the advantages and disadvantages of screen protectors?

1. Advantages of mobile phone screen film

①Protect the screen from scratches and breakage

Mobile phone screen protectors can effectively protect the screen from scratches and damage. When using a mobile phone, some hard objects in your trouser pockets, such as keys and coins, can easily rub against the phone, which can more or less cause scratches on the phone screen, thus affecting the viewing and use of the screen. Therefore, screen protectors can effectively alleviate this problem. At worst, you can just replace it with a new screen protector.

②Prevent fingerprints and dirt

Screen protectors can prevent fingerprints and dirt from sticking to your phone. When using a phone, it is inevitable that your fingerprints will be left on the screen. Especially when your palms are sweaty, the screen is likely to have many fingerprints, affecting the use of the screen. Screen protectors can effectively alleviate this situation and better protect the cleanliness and clarity of the screen.

③Prevent radiation and blue light damage

Mobile phone screen protectors can effectively prevent radiation and blue light damage. Using mobile phones for a long time may cause a certain degree of damage to our eyes, especially in poor lighting conditions, where the glaring light can cause discomfort to the eyes. Screen protectors can effectively reduce the penetration of radiation and blue light, thereby better protecting our eyes.

2. Disadvantages of mobile phone screen film

①Affects the clarity and color accuracy of the screen

Mobile phone screen protectors can affect the clarity and color accuracy of the screen. The light transmittance and color accuracy of the screen protector are important factors that affect the screen protector. In particular, many mobile phone screen protectors on the market are of low quality and are very likely to cause reflections, color differences, and other problems, which can affect viewing and using the screen.

②Affects the feel

Screen protectors for mobile phones will affect the feel of the phone. Screen protectors will increase the thickness and weight of the phone, making it bulkier and worse to hold. For some people who pursue a thin and light feel, screen protectors may affect their user experience.

③Affect heat dissipation performance

Screen protectors for mobile phones can affect the heat dissipation of mobile phones. Mobile phones generate heat during use, and screen protectors may hinder the dissipation of heat. Over long periods of use, this may cause the phone to heat up more severely, affecting the performance and life of the phone.

In summary, whether a mobile phone screen protector is needed depends on personal needs and usage habits. If you care about protecting the mobile phone screen from damage, a screen protector may be a good choice; if you prefer the feel of a bare phone and do not have high requirements for the protection of the mobile phone screen, you can choose not to put a screen protector.
