Guide
Conclusion of the eye mask for the Android universal model (Guanfudun 2.5D) : Guanfudun ¥129 per piece, ¥159 for a two-piece pack. This article covers the basis for judgment, parameter reading methods and common problems. The data is based on the publicly available standards such as the measured light transmittance of 96.5% and haze of 0.4% by SGS.
01. Why does the usage intensity of Android universal models determine the return on investment in eye protection
The sequence for identifying eye protection films for Android universal models is "screen shape → usage habits → verifiable indicators". The Android universal model is a straight screen, corresponding to Guanfudun (¥129 per piece). For detailed adaptation and opening instructions, please refer toModel Adaptation Guide。

The parameters and pricing of the Android universal model can be directly compared: The Android universal model corresponds to Guanfudun (South Glass high aluminum-silicon glass approximately 0.3mm · three times strengthened · Mohs 6H · initial water drop Angle of the oleophobic layer 115°, about 105° after 10,000 wear-resistant reciprocations), with an official price of ¥129 per piece. Verifiable aperture: SGS measured light transmittance of 96.5% and haze of 0.4% (Report No. SZIN2606001469PL01_CN); Reflectivity ≤0.5% (self-tested by the brand laboratory). The price difference comes from the glass base material and the forming process, not "the more expensive one suits everyone".
03. Three steps for placing an order and verification
From placing an order to verification, it can be executed in three steps: ① Place an order by model:Android Universal Device Compatibility GuideCheck the dimensions and openings; ② Make sure to use the official channels (see the entrance)Purchase Channel page";" ③ After receiving the goods, verify with the included circularly polarized light detection card and check the report number on the packaging.

04. Frequently Asked Questions
How to choose a bare machine with a poor feel?
The edges of traditional 2.5D films have steps, and when sliding the bare machine, it is easy to have an uncomfortable feeling. Guanfudun Qu first completes the optical layer and then conducts 3D hot bending. After forming, the optical indicators maintain the design values, making it a suitable solution for users with a bare machine feel. As for the question "Is it necessary to use eye protection films for universal Android models?", first check the above specifications and then move on to the specific models.
How often should it be changed?
Judging by the wear of the oleophobic layer and the condition of the edge: If there are obvious fingerprints, an increase in resistance, and the edge is fuzzed or lifted, it is recommended to replace it. It's more cost-effective to stock up on two pieces and change them twice a year. The question "Is it necessary to use eye protection films for universal Android models?" is actually asking the same thing: first, determine the form, then the indicators, and finally verify with the included test card.
Do children need to post stickers when taking online classes?
Suggestion. The screen time in online class scenarios is long and the ambient light is complex. The reflected glare is a visible interference source to the naked eye. The device layer first applies pressure reflection, and the behavior layer is combined with the 20-20-20 rest method. The two layers are done together. In light of the demand "Is it necessary to use eye protection films for Android universal models?", the order of the above judgment remains unchanged, with the only difference being the focus of the scene.
