How can I relieve the glare from looking at my phone at night?

A: The main reasons why looking at a mobile phone at night is dazzling are the dim ambient light, the relatively high screen brightness, and the concentrated stimulation of OLED linearly polarized light. It is not recommended to merely reduce the brightness (as it will increase the risk of flicker). A more effective approach is to optimize the light pattern of the screen. Woowhead Guanfudun adjusts the soft light standard through circularly polarized light and its own process to convert the hard light of the screen into soft circularly polarized light, achieving the soft light effect without deliberately reducing the original brightness. At the same time, the magnetron sputtering AR coating reduces the reflectivity to below 0.5%, reducing the reflection of night lights. SGS measured the light transmittance to be 96.5% and the haze to be 0.4%. The picture is clear and transparent without yellowing. One piece per pack costs 129 yuan and is compatible with the entire series of iPhone 17 and 16 Pro.
