Bad Quality Screen Protectors Give Bad Views
With the development of tech and the wide spread of smartphone, installing glass screen protectors is becoming a common sense. However, if you get a bad quality protector, it will have negative effect on phone screen display. What’s worse, it could even do harms to your eyesight.
The reason why bad quality protectors do harms to eyesight is that they have low light transmittance. Though some manufacturers claim that their products permit 99% light, the highest quality optical glass (used on lens) has a light transmittance of 98% only. As for PET protectors, they can only reach a transmittance of 90%.
Limited by tech and material, general protectors can’t eliminate diffraction though they are of high definition. As a result, screen display could be unclear and would even cause eye discomfort.
Hardness of Screen Protectors
In order to give nice protection, protectors need to be of a certain hardness. The hardest level of PET protectors is 4H, and now it becomes 9H for glass protectors. However, what does 9H mean? Actually, 9H is a comparison to the hardest pencil and is equal to 7 Mohs hardness. Unluckily, though 7 Mohs hardness protectors could resist keys and knives, they can’t deal with sand.
9H actually means nothing in judging the hardness of screen protector. In addition, when all protectors claim 9H on themselves, it is meaningless to focus on it.
How to Judge the Quality of Screen Protector?
Though glass protectors are popular, most customers can’t judge the quality of protectors. Then how to judge their quality?
1, packaging: glass protector are more easily to be broken while transportation, then good quality ones usually come with nice package. On the contrary, bad quality ones have simple protection only.
2, installation accessories: good quality protectors have some installation accessories as enclosure to ensure well installation. As for those bad quality ones, a screen wiper is enough.
3, anti-fingerprint: actually, anti-fingerprint doesn’t mean completely fingerprint proof because there’s no any possible protector. Dropping a drop of water on it is a nice way to judge since a good protector keeps uniting the drop. In addition, a good protector could resist ink pen writing, and that’s another way to judge the quality of protectors.
4, fitness: good protectors use OCA optical adhesive so as to stay slim and enable automatic installation. What’s more, these protectors can be reused for several times. Of course, a bad quality protector doesn’t have these features.
5, burst proof: when a good quality screen protector accidentally broken, it will stop broken pieces from splash.
