What is Mobile Tempered Glass?
Tempered glass is a type of toughened glass that undergoes a special heating and cooling process to make it stronger and more durable than normal glass. It is designed to absorb impact and break safely into small blunt pieces instead of sharp shards.

How It Protects Your Screen

Shock Absorption

When the phone falls, the tempered glass takes most of the impact force.

Instead of the phone screen cracking, the tempered glass may break, saving the original display.

Shatter Protection
-
If the tempered glass breaks, it shatters into tiny blunt pieces instead of sharp shards, keeping the display intact and safe.

Anti-Fingerprint & Smudge Layer
-
Most tempered glasses come with an oleophobic coating that resists fingerprints, keeping the screen clear.

Blue Light & Glare Reduction (Optional)
