The things you learn. I thought that was a factory coating. Thanks.Ya @Wesleypipesyo you can add premium AR coatings to already cut lenses, sure. Certain brands like Crizal can't be added to cut lenses. But zeiss coatings can... For $96 I can add Zeiss Allure Backside anti glare. You wouldn't add it to the front as the mirror Iridium coating is already hydrophobic now.
But it'll hold up for 1 year under abuse/misuse... Hold up about 3 years for most people with daily use... 7-10 years for minimal and display use easy.
