Alcohol has never affected my plastic lenses.
There are some plastics it affects, I've just never seen it affect glasses. Notably, the eyeglass cleaner kits at eyeglass shops are alcohol based.
Alcohol will affect acrylic/plexiglass, but its not necessarily a fast reaction. I don't know what specific plastic glasses lenses are made of. Also, the UV coating might protect them from the alcohol.
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.
Makes sense, given alcohol comes in plastic bottles
