8K Tempered Glass vs. 9H Tempered Glass: What is the difference?
Confused by screen protector terms? We break down 8k premium glass and 9h tempered glass definitions.

If you are shopping for a screen guard, you have probably seen terms like "9H Hardness" and "8K Premium Glass". What do they actually mean?
* **9H Hardness**: This refers to the pencil hardness scale. A 9H rated glass cannot be scratched by anything softer than a 9H hardness mineral (like keys or coins). Almost all quality tempered glass is 9H rated. * **8K Premium Glass**: This is a term used for ultra-high clarity aluminosilicate glass. It features double-tempered treatment and superior polishing, ensuring that pixel visibility remains crystal clear without any rainbow effects or distortion.
For premium iPhones, we recommend our 8K Premium Glass which combines 9H scratch resistance with maximum optical clarity.
