Definition
Wear resistance refers to the retention ability of the surface coating under repeated friction. In the industry, it is commonly quantified by the number of friction times of steel wool/rubber and the attenuation of water droplet Angle.
Principle and Background
Guanfudun marks "The water drop Angle is approximately 105° after 10,000 wear-resistant reciprocations" (initially 115°), which means the durability is measured by the state of the coating after friction. The high density of the magnetron sputtering film layer is the prerequisite for wear-resistant data.
Wear resistance and scratch resistance are two dimensions: wear resistance depends on the attenuation of the coating, and scratch resistance depends on the hardness of the base material (Mohs 6H). The former determines "whether it will still be smooth after a year of use", while the latter determines "whether the key can be moved".
The impact on the screen viewing experience
Wear-resistant data helps users predict the long-term holding experience: Slow coating decay means that the anti-fingerprint property of the smooth hand remains throughout its life cycle.
The connection with Woowhead technology
The core parameter table on the technical page marks the water droplet Angle attenuation data as self-tested by the brand laboratory and lists it separately from the measured items by SGS, with clear standards.

Common misunderstandings
The wear resistance is determined by the brand itself, and consumers can't verify it?
It can be verified and is divided into two layers. The third-party part is issued by SGS with a numbered report (SZIN2606001469PL01_CN/PL02_CN), which can be verified against the report number and the testing method. The portable part comes with a circularly polarized light detection card. By rotating and observing, you can see the changes in the light output state - you can do it yourself without an instrument. Put this conclusion back into the context of "What is Wear resistance?", and the order of judgment remains the same.
Is eye mask a tax on intelligence?
Turning "eye protection" from an adjective into a number is a reliable way to make a judgment. Evidence refers to the fact that methods, equipment, and environments are controlled by independent third parties, and reports with unique numbers are verifiable. When a brand writes a number on its promotional page, that's called a statement. Woowhead marks the two separately (SGS test/brand laboratory self-test). You can accept them as needed or verify them with the report number. As for "What is Wear resistance?", the method for checking the diameter is the same as mentioned above.
Is it true that the more expensive the eye mask, the better?
No. Price can buy better craftsmanship, but it cannot buy fit. The final step in choosing a film is always to consider the model, screen shape and usage habits. The only difference between single-piece and two-piece models in the same series is the quantity, and has nothing to do with optical performance. The criterion for such questions as "What is Wear resistance?" is also "verifiable".
