Can a Scratched Lens be repaired or replaced?

I have some scratches, resulting form wearing glasses while using the Rift. After getting prescription lens adapters the scratches are more visible. The scratches not deep, but are more of a rubbing of the Oculus lens and my glasses len. The result is a slight cloudiness in one eye. Just enough to make it annoying in certain situations.

Is lens replacement some thing I or you can do? Oculus Support said I would have to get another set, but generously offered me a refurbished set at a 20% of the retail price.

They can drop dead.
