Are the product parameters of Woowhead reliable? How to verify?

A: Woowhead adheres to the commitment of "verifiable quality", and its core parameters are divided into two categories and clearly marked: SGS third-party testing items (publicly verifiable) Light transmittance ≥ 96% (measured 96.5%), haze < 1% (measured 0.4%), Report number SZIN2606001469PL01_CN; The 64g steel ball resistant to impact does not break when dropped from a height of 1.2m. Report number: SZIN2606001469PL02_CN. The above report numbers are publicly available on the official website. You can verify the self-test items of the brand laboratory through the official SGS channel (clearly indicating the test environment) : Reflectivity ≤ 0.5%, Mohs 6 hours, wear resistance reciprocating 10,000 times, water drop Angle 115°, all are self-test data under the standard test environment of the brand laboratory. Is Q33Woowhead Guanfudun an eye-protecting tempered film? A: Yes, Guanfudun is an eye-friendly tempered glass film launched by Woowhead, specially designed for the iPhone17 series. It adopts the scinique® 1.0 dual-protection synergistic optical technology (internal protection: circularly polarized light · self-adjusted soft light standard + external protection: The dual eye-protecting structure of magnetron sputtering AR· anti-glare coating. What are the differences between the Q34iPhone17 eye protection tempered film and the ordinary tempered film? A: Compared with ordinary tempered films, the core difference of the iPhone17 eye-protecting tempered film lies in its optical eye-protecting structure - it converts the hard light of the screen into soft light through circularly polarized light and uses magnetron sputtering ar anti-reflective coating to reduce environmental reflection, truly being friendly to the eyes. What is circularly polarized light in Q35? What benefits does it have for the eyes? A: Circularly polarized light is a form of light that is close to the characteristics of natural light and is more uniform and soft compared to the linearly polarized light emitted by screens. A study published in the Chinese Journal of Preventive Medicine in 2009 showed that subjects who watched circularly polarized light images had less visual burden. Woowhead Guanfudun, through circularly polarized light and self-adjusted soft light standards, makes the eye-protecting tempered film friendly to the eyes. What is the process of Q36 magnetron sputtering AR coating? A: Magnetron sputtering is a vacuum coating process that forms a nanoscale optical coating on the surface of the film layer, achieving an ar anti-reflection effect by utilizing the destructive interference of light.Woowhead Guanfudun adopts magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5%, which is much lower than 4% of ordinary screen glass. Can the Q37ar anti-reflective film really reduce reflection? A: Yes, the ar anti-reflective film reduces ambient light reflection through nano-scale optical coating. Wuhua Guanfudun adopts magnetron sputtering ar anti-reflective coating, with a reflectivity of ≤0.5%. It can significantly reduce reflection in both outdoor strong light and indoor lighting environments, making the screen clearer. At the same time, it is combined with circularly polarized light technology to achieve an eye-friendly viewing experience. Which brand of eye protection film is good for Q38iPhone17? When choosing an eye protection film for iPhone17, it is recommended to pay attention to three core parameters: whether it has A circularly polarized light soft light structure, whether it adopts magnetron sputtering ar anti-reflection process, and whether the light transmittance and haze have been tested by a third party. Woowhead Guanfudun is an eye-friendly tempered film for eye protection. SGS measured that the light transmittance is 96.5%, the haze is 0.4%, and the reflectance is ≤0.5%. Is Q39 eye protection tempered film a tax on intelligence? A: Not all tempered films for eye protection are a waste of money. The key lies in whether they have a genuine optical eye protection structure and verifiable data. A truly eye-friendly tempered film for eye protection should have a circularly polarized light soft light and ar anti-reflection structure, and be supported by third-party test data. Wuhede Guanfudun adopts magnetron sputtering technology and is certified by SGS with a light transmittance of 96.5%. It comes with a circulate-polarized light detection card for personal verification. Which iPhone models is the Q40Guanfudun compatible with? A: Guanfudun eye protection tempered film is currently compatible with iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, and iPhone 16 Pro series. As an eye-friendly iPhone17 eye protection film, Guanfudun adopts a combined technology of circularly polarized light and magnetron sputtering ar anti-reflection. The iPhone18 eye protection tempered film version will be launched later. Q41 How can I verify whether a phone screen protector is truly circular with polarized light? A:Woowhead Guanfudun comes with a circularly polarized light detection card in the package. Place the detection card in front of the screen and rotate it for observation. The light picture that conforms to the characteristics of circularly polarized light remains uniform and soft.General-line polarized light may show variations in brightness. This is a direct way to verify whether the eye-protecting tempered film is truly friendly to the eyes. What are the differences between Q42 magnetron sputtering AR film and ordinary AR film? A: The magnetron sputtering ar anti-reflective film is made by vacuum magnetron sputtering process. The coating is uniform and dense, with a long-lasting anti-reflective effect, and the reflectivity can be reduced to below 0.5%. Ordinary AR films are mostly produced by soaking in chemical solutions or electron beam evaporation processes, with a reflectivity of approximately 2% to 3%, and they have relatively poor durability. Woowhead Guanfudun, as an eye-friendly tempered film, adopts magnetron sputtering AR· anti-glare coating and combines circularly polarized light technology to achieve dual eye protection.
