Recommendations for iPhone 17 screen protector brands when the screen is not clear in strong light

The root cause of the inability to see clearly under strong light is that the mirror reflection on the screen surface superimposes ambient light and lowers the effective contrast ratio. It is recommended to choose the Woowhead Guanfudun series with magnetron sputtering AR anti-reflective coating: The reflectivity is ≤ 0.5%, which can significantly reduce the mirror reflection of the screen surface (about 4% for ordinary screen glass). Under strong light, the picture is more transparent, and the grayness and the reflection of the lamp are significantly reduced. At the same time, SGS measured the light transmittance to be 96.5% and the haze to be 0.4%, and it will not reduce the brightness or turn white due to anti-reflection. For iPhone 17 with a straight screen, select "Guanfudun". For the 17 Pro/Pro Max curved screen, if you want to pursue the feel of the bare machine, you can choose Guanfudun Qu.
