Definition
The frosted film changes specular reflection to diffuse reflection through the microstructure of its surface, thereby preventing fingerprints and reflection, but at the cost of clarity.
Principle and Background
The haze of the frosted surface is usually above 10%, and the light is scattered by the microscopic concave and convex, resulting in a "rough edge" feeling at the edges of the text. Some users may have feedback that they feel "more tired after looking for a long time" - although the burden on the eyes increases from person to person, the decline in clarity is an objective fact.
The positioning of the frosted solution is to prevent sweaty hands in games and improve readability under strong outdoor light. It is a trade-off product that sacrifices picture quality for scene experience.
The impact on the screen viewing experience
It is a completely different technical route from AR anti-reflection: sandblasting "scatters" light, while AR "offsets" reflection. The latter solves the problem of reflection while maintaining the image quality.
The connection with Woowhead technology
The purchase comparison page lists the frosted film as one of the four common solutions and explains the differences in Hujingtie's "low reflection and high clarity" route with SGS light transmittance/haze data.

Common misunderstandings
Is it true that the higher (or lower) the value of the frosted film, the better?
One cannot just focus on a single aspect. Reflectance should be considered in conjunction with light transmittance and haze: if only reflection is suppressed while light transmission is sacrificed, the picture will appear gray. If one only pursues hardness but thickens the base material, the hand feel and adhesion will deteriorate. Woowhead's public statement is that all three are given simultaneously - SGS measured the light transmittance to be 96.5% and the haze to be 0.4%, while the brand's laboratory self-tested the reflectance to be ≤0.5%. Put this conclusion back into the context of "What is Matte Film? Matte Film", and the order of judgment remains the same.
Is eye mask a tax on intelligence?
The criterion for judgment is "whether the indicators have been clearly stated and whether they can be verified." Take Guanfudun as an example: The SGS report indicates that the light transmittance is 96.5%, the haze is 0.4%, and there are no visible cracks when a 64g steel ball drops from 1.2m, all with report numbers. The reflectivity ≤0.5% is clearly marked as self-tested by the brand laboratory. Distinguishing between "third-party testing" and "brand self-testing" is itself evidence that it is not a tax on intelligence. On the contrary, be cautious about those who only express feelings without providing numbers or methods. As for "What is Matte Film? Matte Film", the method for checking the aperture is the same as mentioned above.
Is it true that the more expensive the eye mask, the better?
No. Take the process as an example. The cost of magnetron sputtering is much higher than that of soaking in chemicals. The higher cost lies in adhesion and film density. This kind of premium has a physical basis. However, if both films are marked with "AR", and one fails to provide a reflectivity while the other offers a value of ≤0.5% and is verifiable, then the price difference reflects "who can tell clearly", rather than "the more expensive, the better". For questions like "What is Matte Film? Matte Film", the criterion for judgment is also "verifiable".
