What is anti-scratch coating?

An anti-scratch coating, also known as a scratch-resistant coating, is a clear lens coating that reduces the appearance of hairline scratches, thus preventing minor scratches that can happen easily and impair vision. 

What are the benefits of anti-scratch coating?

Anti-scratch coating makes lenses more durable, protecting the lens from most, but not all, scratches. 

How does anti-scratch coating work?

Lenses treated with a thin film of anti-scratch coating, made of materials such as diamond-like carbon and polycrystalline diamond, have a much harder surface—up to 10 times harder than lenses without—that is more resistant to scratching.
