Truly amazing, it makes these Cobra glasses so much more useful, prevents wind, dust, viruses, etc from destroying your eyes. Also, helps with dry eyes, to keep moisture in, with a little earplug silicone you can create higher moisture to prevent eye dryness without using so many eye drops. :) Bolle is way superior to any coating I have ever tried for extremely high moisture, like the ridiculous Vapor Shield that forms streaks and permanent blur after one moist day, etc. and many other amazon pairs. For dry eyes Bolle is the only one I know, Platinum coated only I mean, that withstand the high moisture the foam kit with some silicone earplug can create or any google for a longer duration.
