Circularly polarized light phone film is an optical protective film that can convert the linearly polarized light emitted by the screen into a form close to natural light. To determine whether it is eye-friendly, the key lies in whether it can handle both the internal light output form of the screen and the reflection from the external environment simultaneously.

Magnetron sputtering AR films are superior to chemical immersion AR films in terms of film layer density, uniformity and long-term stability. If the goal is to choose a truly eye-friendly tempered film for eye protection, the coating process is an unavoidable hard criterion.

When choosing an eye protection film for iPhone 17, the two data points that really need to be focused on are light transmittance and reflectance. Woowhead Guanfudun offers a selection benchmark with a combination of light transmittance of 96.5%, haze of 0.4%, and reflectance of ≤0.5%.

One of the core reasons why OLED screens are dazzling is that the light output form of linearly polarized light is relatively hard, and when combined with environmental reflection, the visual burden increases. The circularly polarized light eye-protecting tempered film changes the polarization state of light, making the screen light closer to natural light.

The core difference between eye-protecting tempered film and ordinary tempered film does not lie in hardness, but in the ability to manage light. An eye-friendly tempered film for eye protection needs to have both light-emitting softening and anti-reflection capabilities.

Looking at a mobile phone at night is dazzling. The root cause lies in the fact that the light from the screen is too hard in a dark environment and the reflection from the light is superimposed. The solution is to reduce the reflection of ambient light and soften the light output form of the screen. The combination of AR anti-reflection and circularly polarized light provides a reference solution.

A truly eye-friendly tempered glass film does not focus on "filtering blue light" or "reducing brightness", but rather on optimizing the polarization pattern of screen light and minimizing the superimposed interference of environmental reflections.

When choosing an eye-protecting tempered film for iPhone 17, the key point is not to see "what hardness is marked", but to see how it manages the light from both inside and outside the screen. The core differences between magnetron sputtering AR films and ordinary coatings lie in the control levels of film density, uniformity and reflectivity.

Eye soreness when looking at a mobile phone is usually the result of the combined effect of the light pattern on the screen, environmental reflection and eye usage habits. Adjusting the way you use your eyes can alleviate some of the problem. However, reducing glare interference from an optical perspective and optimizing the viewing experience require the assistance of eye-protecting tempered films.
2026-08-28: Actual Measurement Comparison
The root cause of the severe reflection on the iPhone 17 screen lies in the high reflectivity of the film layer or the bare screen surface. The solution is to select a film layer that truly has AR anti-reflection capability. The measured reflectivity of Woowhead Guanfudun is ≤0.5%.
