myth: These Lenses are Scratch-Proof
fact: No lens yet developed is truly scratch-proof. There is always some material which can scratch a lens. A diamond can be scratched by another diamond. Lenses instead should be termed scratch-resistant. A plastic lens with a scratch-resistant lens is more durable than a lens without the coating. Glass to this date remains the most scratch-resistant material – more durable than plastic with a scratch-resistant coating
