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.
The really annoying thing is that these coatings used to be optional paid extras, and when I got some new lenses for the first time in almost a decade they quickly became blotchy and awful so I went back to get some more but this time with zero coatings.
Specsavers told me that's wasn't possible, that ALL lenses have these coatings now, it's not even optional.
Glasses lenses used to last years and years, now they're blotchy crap after only 3 or 4 years. Bloody ghets know what they're doing. And ripping us off while they're at it with their high prices £££
These coatings are optional extras you were lied to. They may put an anti scratch, but, an anti-reflective coating is optional. They may just make it a mandatory add on to boost their profits. The lenses I have are about 4 years old. They are scratched to shit because they are plastic, but, no coating coming off. They use plastic because it's easier to make, cheaper for you and way lighter. You can request glass if you want. Glass gives you better clarity, better scratch resistance, but, if you drop them they could shatter. They will also be a lot thicker.
I've had pretty decent luck ordering prescription glasses from the big online glasses retailer, you know the one, starts with a Z.
I still gotta pay $100 for glasses but that's way better than the $400 they cost retail.
