James,<br><br>The coating is extremely effective - used to scuff up lenses regularly; no scratches on these, period. Don't remember the cost - maybe $20 extra? A lot cheaper than new lenses...<br><br>The lenses pass an ANSI test - think safety glasses. Not technically safety glasses because there are no side shields, but it's better than not rated. Will not keep things together any better if dropped, however.<br><br>Tom
