The virus reaches your eye via droplets in the air. They either reach your eye or they don't. If they flow around the lenses, no treatment makes any difference. If they splat on the lens surface, they aren't going to reach your eye whether the lenses are glass, plastic, coated, uncoated. If your lenses are made of swiss cheese, then you are at risk, but all the other lens materials are not porous enough to allow through-passage to even virus-sized particles.

It seems this isn't a new concept. Uncle Fester posted a link to a patent that was applied for 06/12/2013. Silver ions being used in smart phone screens. I found a recent (covid era) article about why it's not being used in most smart phones today. Just a little more info for y'all to digest. https://www.wired.co.uk/article/why-...e-clean-itself

So I've reached out to our VSP rep a few times over this since it was introduced. They still can't really tell us how it works or is applied. But they're saying the anti bacterial properties are in the AR coat and hard coat itself. And create a surface environment that eradicates bacteria. They also say the properties are retained for the life of the coating. Let's be honest. The only reason they're doing it is to have a coating that enables them to make the Unity products mandatory going forward with the changes in reimbursements. It's their safety net. It's mandatory because we have this and no one else does. That's my thought on it. It's supposed to protect against the build up of bacteria on the lens. But it feels way more gimmicky and just a way to protect themselves more than anything.

No product reached the market until the 1960’s. Mostly due to non acceptance of the concept by the optical community. When the early adapters starting selling progressives it was a very rocky rd. Sell 1, sell 2, sell 3 and them number 4 is a dismal failure. I will never sell these lenses again was a constant call. Look where we are now. New concepts take patience, time and a desire to lead not follow.
