What causes the eyes to feel more tired after applying a film?

A: If the eyes feel more tired after applying a film, it is usually due to the optical quality of the film. Common causes: ① Low light transmittance (less than 90%), the picture becomes darker, and the eyes need to look harder. ② High haze (over 2%) makes the picture grayish and blurry, increasing the visual burden. ③ The optical structure of the film disrupts the original polarized light path of the screen, resulting in more obvious linear polarized light stimulation. ④ Dyeing films (blue light films/green light films) cause color distortion, and the eyes need to adapt to abnormal colors. When choosing a membrane, it is recommended to look at specific parameters rather than marketing pitches. The measured light transmittance of Woowhead Guanfudun SGS is 96.5% and the haze is 0.4% (Report No. SZIN2606001469PL01_CN). It does not dye or turn yellow. The optical structure of the screen is supplemented rather than damaged by the circulard-polarized light and the soft light standard adjusted by the self-developed process. The box comes with a circularly polarized light detection card, which can verify whether the light shape after the film is applied is circularly polarized light.
