It is very important to NOTE that Essilor has changed the way in which they are going to evaluate scratch resistance. They have traditionally relied upon Bayer Abrasion testing to quantify this. Now they have introduced their own "proprietary" method claiming that the Bayer test is conveniently outdated. I am not sure how they can assert these claims when they have changed the evaluation method. I have no doubt that the new stack and hard coating will produce a more scratch resistance product but shouldn't we all get a look at that data once it has been put through the same testing protocols as past recipes?
It is important to also be aware that Essilor didn't change the superhydrophobic/oleophobic topcoat at all. They just swizzled some marketing words around to make it sound new and improved. It is the same material they have used for many years now. I can honestly attest that it has always outperformed just about every other available product on the market but there are several of us manufacturers that are using it in our comparable products.
