Anti-Fog lenses have an embedded water resistant compound on the inside of the lens.  For use in fresh  or salt water.  Keep clean with soft soap.  With proper care these lenses will offer many fog-free dives. Use in treated pools will eliminate the water resistant compound, after which the standard anti-fog drops may be used as with untreated standard mask lenses.
