I have worked in optical, that coating is the anti-reflective coating that is coming off. You cannot take that coating off. It is baked on. Harsh chemicals will destroy the plastic lenses. It just degrades and comes off after a while, generally if it is less than 2 years they should be under warranty.

Thankfully it is glass, I may just have to take this to an optometrist and see if they can do it for me

Just curious what country are you in? If you're in the USA why glass? I'm in the US and default material is plastic.

I don't think that's the default material, I've been moving around the US since 95' getting glasses in each state once a year when I was still on my parents insurance and every time I just get normal glass.

That might just be your provider or something

Lol I was in the business for 10 years. Cr39 or polycarbonate is the most common material. There is a high index, I forget what the material is, for higher prescriptions because you can get the material thinner. Glass isn't very common, it's more expensive, it's heavy, it's thicker, and it's fragile. I'm not saying you don't have glass, it's just not the most common material. Very possible there was a notation made on your script by the optometristic telling the optician you need glass and that may be why you've had glass this whole time.
