You want scratch resistance and you want it now? Try the close cousin
to the armor, aluminum oxide. Used for bar scanner windows. Very
scratch resistant, maybe not as good as this new armour, but good.

Someone here was offering samples at one time. A place that grinds
lenses for eye glasses could probably make you some lenses. They use
diamond wheels for regular glass.

My last (recent ) set of glasses with glass lenses are very abrasion
sensitive. The lenses are uncoated. Has the lens glass been getting softer
to make the manufacturing easier? It really bugs me that my old glasses were
about ten times more scratch resistant than the new ones.
