I would think you could do the same thing I did to remove the scratch's from my eye glasses.
The most popular remedy for plastic lens scratches is a glass-etching product called Armor Etch. Armor Etch removes the anti-glare and anti-scratch coatings on plastic lenses, leaving the original plastic lens intact. Because it is a glass-etching chemical, it does not affect plastic but must not be used on glass lenses. Other abrasive products like cleansers also remove the lens coatings without harming the original plastic lens beneath.
Not sure if were talking about the same thing but... Mine were starting to peal over time so I just went with it and took it all off. A heat gun and tape works best for that. Heat up an area and apply some clear tape, then rip it off. It takes some time but they will look new again.
