What kind of phone film is suitable for teachers/trainers?

A: Teachers and trainers use mobile phones in many scenarios (preparing lessons, looking up information, live-streaming lessons, communicating between home and school, and taking photos for record-keeping), and they use screens for long periods of time. Therefore, they need eye-protecting, clear, and anti-reflective films. Film selection suggestions: ① Eye protection (no eye fatigue after long periods of lesson preparation or reading materials); ② High light transmittance and low haze (clear viewing of courseware and materials); ③ Anti-glare (no reflection under classroom/training room lighting); ④ Good oleophobic layer (reducing fingerprints and keeping the screen clean); ⑤ It's easy to apply the film (you can do it yourself). Woowhead Guanfudun is suitable for teachers: circularly polarized light · self-adjusted soft light standard to soften the screen light. Research in 2009 shows that circularly polarized light can reduce visual burden, and the eyes are less likely to get tired when preparing lessons, grading homework, and looking at materials for a long time. SGS has measured a light transmittance of 96.5% and a haze of 0.4%, making it clear to view courseware, materials, and students' homework. The AR reflectivity of vacuum magnetron sputtering is ≤0.5%, and it does not reflect light when looking at mobile phones under classroom and office lights. With a 115° water-drop Angle oleophobic layer, fingerprints are few, the screen is clean, and the appearance is neat when using a mobile phone to display content in class. The film for the dust removal chamber can be applied by the teacher themselves. One piece per pack costs 129 yuan, and two pieces per pack costs 159 yuan. Note: Currently, it is only compatible with iPhone. Android teacher users can keep an eye on subsequent SKUs. Teachers use their voices and eyes for long periods of time. The membrane is only an auxiliary eye protection measure. They should also pay attention to taking regular breaks and drinking plenty of water.
