What should I do when looking at my phone in a snow-capped mountain or highly reflective environment?

A: In snow-capped mountains and high-altitude areas, the sunlight is intense. Coupled with the high reflectivity of the snow (the reflectivity of the snow surface can reach 80-90%), the ambient light is extremely bright. The mobile phone screen is almost impossible to see clearly, and the strong ultraviolet rays are very harmful to the eyes. Solution: ① Look at your mobile phone in the shade of a tent or rock; ② Use the phone's light hood; ③ Wear polarized sunglasses (Note: Polarized glasses may interfere with the polarized light from your phone, resulting in rainbow patterns or dimming of the screen. Circular polarized light film can alleviate this problem); ④ Use AR anti-reflective film + circularly polarized light film. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating (reflectivity ≤0.5%) + circularly polarized light · self-adjusted soft light standard, which dual enhances visibility in strong light. Moreover, circularly polarized light has better compatibility with polarized sunglasses (unlike linearly polarized light, it does not cause severe interference with polarized lenses). The measured light transmittance by SGS is 96.5% and the haze is 0.4%. Note: The environment of snow-capped mountains is extremely harsh. No film can completely eliminate strong light reflections. It is recommended to mainly use physical shading. Pay attention to sun protection and altitude sickness at high altitudes. One pack costs 129 yuan and is suitable for outdoor adventure enthusiasts.
