"The colour LCD screens on cellphones and PDAs can get badly scratched in pockets stuffed with loose change and keys. And CDs and DVDs become unplayable in no time when children use them as indoor frisbees. Now a tough, transparent polymer coating developed by chemists in Japan is set to make scratched phone screens and scuffed discs a thing of the past...."

How 'bout flashlight lenses too?...

Looks like it's just a thin layer of glass bonded to the disc / screen. Unfortunately glass still isn't scratch proof. It is used in flashlight lenses as well.

The really good stuff is sapphire crystals. Mohs hardness of 9.
