Pulling this straight out of my ass but I think it’s likely to be polycarbonate

I worked in optical it's polycarbonate. Can be a plastic called cr39 or it could be a high index lens if they have a very high prescription generally alcohol won't hurt it. If the frame is plastic the alcohol could potentially fog the plastic.
