Speaking of tempered film, I believe many people are familiar with it. It mainly refers to a toughened glass film with strong wear resistance, which can help us better protect the mobile phone screen, and has the characteristics of scratch resistance and no air bubbles. In the mobile phone film market, there has been an anti blue light tempered glass screen protector. Is it really useful? Now we will learn the relevant knowledge with you.


Ⅰ. Is anti blue light tempered glass screen protector useful?


The real anti blue light tempered glass screen protector can block high-energy short-wave blue light (400nm~470nm band) that is harmful to the eyes. It can also care for the eyes and protect eyesight. The anti blue tempered glass film, which uses the thousand-layer nano-layering technology, combines the principle of light refraction and reflection, and is developed with imported ultra-thin nano glass and top optical-grade materials. It has good scratch resistance, anti-drop, anti-fingerprint, waterproof, anti-radiation, anti-oil and other characteristics, while protecting eyes and the safety of the mobile phone screens.

1. With a 90° field of view, looking directly at the screen of the mobile phone, the anti-blue light tempered glass film presents a light blue and slightly purple light.


2. With a 30° field of view to the left, looking directly at the phone screen, the anti blue tempered glass film will appear colorless and transparent.

In fact, the simplest understanding of blue light is that it will suggest that we should not sleep now. And our main sources of blue light exposure are mobile phones and computers. If we stay in blue light for a long time, it will cause great damage to our human body, especially to the retina.


Therefore, many mobile phone manufacturers have introduced anti blue light tempered glass screen protectors. Although it can effectively reduce the damage of blue light to the eyes, we still recommend that everyone pay attention to the frequency of mobile phone use and do not face the mobile phone screen for a long time. If you use it for a long time, look at the green plants and let your eyes rest.
