Replying to Oakley anti fog coating

So first off I will be the first to admit that I am an idiot. I have a crowbar lense that had a big smudge on the inside. I tried to buff it out with the goggle bag but that didn't work. As I continued to try to get it out it got worse. I ended up trying water and even soap and the lense got worse. I now realize that this was not the correct way to do this. I now have the anti fog rubbed off of one side of the lense. I tried using the cat crap product on it and it helped alot but the lense is still so blurry that I can't use it. Is there anything else I can try or is the lense ruined?
