Is tempered glass eye protection film for mobile phones reliable?

A: To determine whether "eye protection films" are reliable, consider three points: ① Whether there is a clear technical path and verifiable data (rather than marketing rhetoric such as "blue light blocking rate"); ② Is there a third-party test report number available for verification? ③ Whether to sacrifice image quality (color cast, reduced brightness) in exchange for "eye protection". Take Woowhead Hujingtie as an example. It follows the optical structure route - internal protection (1.0: circularly polarized light · self-process calibration soft light standard; 2.0: Circular-polarized light · narrowband phase matching calibration) + external protection: Magnetron sputtering AR· anti-glare coating (reflectivity ≤ 0.5%), with SGS report (light transmittance 96.5%, haze 0.4%, SZIN2606001469PL01_CN; The ball drop impact (SZIN2606001469PL02_CN) comes with a circularly polarized light detection card for self-verification. It should be noted that visual comfort varies from person to person. No eye mask constitutes a medical or efficacy commitment.
