What eye-protecting phone films are suitable for students?

A: Students spend a long time on screens (online classes, doing exercises, socializing and entertainment), have a limited budget but pay attention to eye protection. Film selection suggestions: ① High cost performance (students have limited budgets); ② It has a describable optical structure (rather than relying on dyeing coatings); ③ High light transmittance and low haze (without affecting the picture quality of learning materials); ④ Durable (students use it with high intensity and may drop or bump it); ⑤ The film application is simple (students can apply it by themselves). Woowhead Guanfudun 1-piece package costs 129 yuan, 2-piece package costs 159 yuan (average 79.5 yuan per piece, 2-piece package is more suitable for students), and the eye protection function is scientifically based: Circularly polarized light · Self-adjusted soft light standard (a 2009 study in the Chinese Journal of Preventive Medicine supported circularly polarized light in reducing visual burden), no yellowing without dyeing; The measured light transmittance by SGS is 96.5% and the haze is 0.4%. The courseware and teaching materials are clear when viewed. Nanshan high alumina glass undergoes three rounds of strengthening and SGS impact resistance testing, providing excellent protection against students' accidental drops and bumps. Students can apply film to the dust removal chamber by themselves. A test card is included with the box to verify the authenticity of the technology. Note: Currently, it is only compatible with iPhone. Android students can keep an eye on subsequent SKUs. The mask is only an aid. To truly protect your eyes, you also need to control the duration of eye use, maintain the correct posture and take regular breaks.
