I have used Oakley sunglasses for probably close to 20 years. I have always liked the fit and styles. However, there is 1 thing that I cannot stand, and that is what seems to be the extreme ease with witch they seem to scratch. I am posting now, because my fairly new half jacket 2.0 iridium lense is scratched. And like always, right in the direct line of sight. I always get the polarized lenses with the iridium coating. I have been thru dozens of replacement lenses over the years. All because they scratch so easily and it gives me a headache to look thru a lense with scratches. So, what is the most scratch resistant half jacket 2.0 lense? And I do take care of my glasses, but I am also a very active person. These are sun glasses and should have a bit better durability than fine china.
