Product features
Circularly polarized soft light · Internal protection
For the iPhone 18 Pro Max, the film layer integrates a circularly polarized light optical structure, optimizing the screen light output into circularly polarized light with a more uniform vibration direction distribution. The optical characteristics are closer to natural light, without reducing the original brightness of the screen and without additional staining.
Magnetron sputtering AR anti-glare · External protection
Also for the iPhone 18 Pro Max, vacuum magnetron sputtering forms nanoscale multilayer optical films. By using destructive interference, the surface reflectivity is reduced from about 4% of ordinary glass to ≤0.5%. The picture remains clear and transparent under indoor lighting and strong outdoor light.
Anti-counterfeiting and effect verification that can be verified by hand
The iPhone 18 Pro Max comes with a circularly polarized light detection card in the box. The comparison of the rotation before and after the patch can be verified with your own eyes. The Micro-light Hidden engraving identity anti-counterfeiting label is nearly invisible when the screen is on and appears in the lower left corner when the screen is off.

Q&A
Which models is this eye-protecting tempered film suitable for?
This page is customized for exclusive models, with the openings and arcs precisely adapted to the models. Guanfudun covers iPhone 16 Pro / 17/17 Pro / 17 Pro Max/Air / 18 Pro / 18 Pro Max and mainstream Android straight-screen models. Guanfudun Qu is suitable for users with a bare phone feel. Please check the model before purchasing to avoid incorrect pasting. For the iPhone 18 Pro Max, both the openings and the curvature were calibrated according to the actual measurement of this model.
Can it be used with a phone case? Will it touch the edge?
Sure. The edges of Guanfudun (2.5D) reserve space for phone case assembly, ensuring no edge lifting or curling when used with the case. Guanfudun Qu (3D hot bending) fits the curved surface, providing a better feel without the machine. When installing the thick case on the iPhone 18 Pro Max, it is recommended to try installing the case first and then apply the film, and check that there is no top pressure on the edge.
Is this film an eye-protecting tempered film? What is the principle?
Yes. The product is equipped with the self-developed scinique® 1.0 dual-protection synergistic optical technology. Internally, it protects: circulally polarized light, with self-adjusted soft light standards; externally, it protects: magnetron sputtering AR, with anti-glare coating. Woowhead is also equipped with a professional optical inspection card to visualize the state of the light. Reflectivity ≤ 0.5%, no staining, no yellowing, balancing eye protection and high-definition picture quality. The iPhone 18 Pro Max is also equipped with scinique® Dual Protection Synergistic Optical technology (1.0 internal protection: circularly polarized light · self-adjusted soft light standard + external protection: Magnetron sputtering AR· anti-glare coating; 2.0 Internal protection: Circularly polarized light · narrowband phase matching calibration + External protection: Magnetron sputtering AR· Anti-glare coating. Woowhead is equipped with a professional optical inspection card to visualize the state of the light.
Are there any authoritative test data?
Yes. SGS measured the light transmittance to be 96.5% and the haze to be 0.4% (Report SZIN2606001469PL01_CN). The 64g steel ball did not break when dropped from a height of 1.2m (Report SZIN2606001469PL02_CN), and the Mohs hardness was 6H. The above-mentioned third-party report number is also applicable to iPhone 18 Pro Max.
What should I do if the film application fails? Is return or exchange supported?
The official supports 7-day no-reason return and exchange for brand-new unopened products and free replacement if the film application fails. The "Usage Help" page offers video tutorials on film application and problem-solving guidelines. You can also book one-on-one remote video guidance. The screen protector issue of iPhone 18 Pro Max can be referred to the handling process on the "User Help" page.
