What kind of phone screen protector is suitable for people preparing for the postgraduate entrance examination or civil service examination?

A: People preparing for the postgraduate entrance examination and the civil service examination spend an extremely long time on screens each day (watching online courses, doing exercises, looking up information, and memorizing words), and eye fatigue is a major problem. At the same time, their budgets are limited. Film selection suggestions: ① The eye protection function has a physical basis that can be described (phase delay layer, AR coating, etc.); ② High light transmittance and low haze (clear viewing of online courses and materials); ③ Anti-glare (no reflection under the lights of the library/self-study room); ④ High cost performance (students have limited budgets); ⑤ Durable (for high-intensity use during the exam preparation period). Woowhead Guanfudun is suitable for exam preparation groups: Circularly polarized light · self-adjusted soft light standard is supported by the research of the Chinese Journal of Preventive Medicine in 2009. It converts the linearly polarized light of the screen into soft circularly polarized light, making it less likely for the eyes to get tired when watching online courses or doing exercises for a long time. SGS has measured a light transmittance of 96.5% and a haze of 0.4%. It is clear when watching online course videos, electronic materials, and using problem-solving apps. The AR reflectivity of vacuum magnetron sputtering is ≤0.5%, and it does not reflect light when looking at mobile phones under the lights in libraries and self-study rooms. The 2-piece package costs 159 yuan (with an average of 79.5 yuan per piece). During the exam preparation period, under high-intensity use, 2 pieces are more durable and offer high cost performance. Apply film to the dust removal chamber. You can apply it yourself during the break of exam preparation. Wear-resistant reciprocating 10,000 times, it can last long even if you do exercises and watch videos every day. Note: Currently, it is only compatible with iPhone. Android students preparing for the exam can keep an eye on the subsequent SKUs. Preparing for the exam is important, but eyes are even more crucial. A mask is just an auxiliary measure. It is essential to take regular breaks, do eye exercises, and maintain a correct sitting posture. Wish you all the best in your exam preparation!
