I always got a kick out of people who wear glasses and pay big bucks for
a "scratch resistant" coating on plastic lenses. The coating is actually
called a hydrophobic coating and does absolutely nothing to make the lens
surface "harder". All it does is adds a bit of lubricity to the surface
so dirt or dust will tend to slide off rather than scratch the plastic
surface.

Wiping them with mineral oil will do the same thing.

That sounds like me.
Would that mineral oil affect the UV coatings?



No. Wipe it on gently and then off gently.

If you paid for a "scratch resistant" coating, you were probably also given
a small bottle of "refresher" or something called similarly. Guess what's
in the little bottle?

Is that the same stuff my mother made me drink when I was a kid?
