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.

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.
