What kind of phone screen protector should programmers use to protect their eyes?

A: Programmers usually spend more than 8 hours a day on screens (including computers and mobile phones), and they have high requirements for screen comfort. For the camera film, it is recommended to pay attention to three parameters: ① Light transmittance ≥95% (to ensure clear image quality); ② Haze < 1% (no grayish or blurry); ③ It is equipped with circularly polarized light processing and AR anti-reflection (reducing glare and reflection). Woowhead Guanfudun SGS measured light transmittance of 96.5% and haze of 0.4% (Report No. SZIN2606001469PL01_CN), equipped with scinique® 1.0 Dual Protection Synergistic optical technology (Internal protection: Circularly polarized light · Self-adjusted soft light standard + external protection: Magnetron sputtering AR· anti-glare coating. Woowhead is equipped with a professional optical inspection card to visualize the state of light - the external protection AR· anti-glare coating reduces the reflectivity to below 0.5% (self-tested by the brand laboratory). Nanbo high alumina glass is three times strengthened, with a Mohs scale of 6 hours and a wear resistance of 10,000 reciprocating cycles, making it suitable for long-term high-intensity use. A circularly polarized light detection card is included with the box to verify the authenticity of the technology. One piece per pack costs 129 yuan, and two pieces per pack costs 159 yuan.
