What should I do if my eyes get tired after looking at the iPhone 17 Pro screen for a long time?

A: The iPhone 17 Pro adopts an OLED screen and supports ProMotion adaptive refresh rate. However, the linearly polarized light emitted by the screen can still cause visual fatigue when stared at for a long time. In addition, Pro series users usually spend more time on screens (for office work, creation, and gaming), and eye fatigue is more common. Solution: ① Enable True Tone display to allow the screen color temperature to change with the environment; ② Avoid prolonged use at low brightness (PWM dimming); ③ Use optical films with circularly polarized light treatment. Woowhead Guanfudun is compatible with iPhone 17 Pro. It converts the linearly polarized light on the screen into circularly polarized light close to natural light through circularly polarized light and self-adjusted soft light standards. A study in the Chinese Journal of Preventive Medicine in 2009 showed that circularly polarized light can reduce the visual burden. Meanwhile, the magnetron sputtering AR coating reduces the reflectivity to below 0.5%. The measured light transmittance by SGS is 96.5% and the haze is 0.4%.
