6 years ago, Essilor introduced Alize. Sola was releasing Teflon at the same time (which was not easy to clean), Zeiss was a couple of years away from releasing Carat Advantage, and Hoya was releasing its lens.
Essilor came out with an easy edging system. The others have not.
Essilor has improved the durability, scratch resistance, easy of clean, and anti-static properties since then, the others have not.
Essilor has a great, cheap stock lens system, the others do not. For instance, in the past I wanted stock Super Hi Phoenix. Hoya told me that it was not a stock lens. So I had to get it surfaced, which cost me significantly more. This was a lens that I could have used for almost all of my Single Vision AR, and I was told that they could not do it. While I could get Alize on a lens for about 20% of the cost.
Same with Zeiss/Sola.
Why have these guys not accomplished these systems that Essilor has? Complacency.
Independent las do have stock lenses with their house coatings on them available, at least mine does. As for coating the easy edging system is a patented process by Essilor which I admit is very nice, but the others recommend an intermediate pad or a more secure edging pad which is acceptable.
Not true teflon has had significant improvements over the years, especially when compared to the first incarnation, same with carat. The difference is that every slight improvement isn't rebranded and priced through the roof. I could confidently say at this point their is nothing I need an AR to do that isn't currently available. At this point they're beating a dead horse, other than putting a cup holder or the kitchen sink in my AR what else is left.Essilor has improved the durability, scratch resistance, easy of clean, and anti-static properties since then, the others have not.
I would be interested in some sort of bechmark on the various tests performed on AR's using Colts methodology. Their should be a correlation to the cost of a coating compared to it's properties, and preferably solid data.
Teflon has had several failures in my former office. Now, let's talk about rebranding. How are we supposed to know that the product is better if the company does not tell us?
Again, behind the time.
