I've done it before, using a Dremel tool with a polishing wheel and wax polishing compound, then toothpaste on a rag.
It took me two days, per lens to get anything close to usably clear. So I hate to say it, but you're probably better off getting new lenses.
TL;DR the next part, shit used to be made to last...
Or, if you hit a dumb stroke of luck like I recently did, get some vintage glasses made in the 1980s. It's very rare that I stumble into prescription glasses that match my prescription, but I accidentally came across a perfect matching pair that was manufactured around 1988, and they just refuse to scratch!
Yes, that's almost impossible to stumble across, but you never know what you might find in a thrift store or flea market.
That’s because they’re glass lenses. The plastic whatever crap is just another form of planned obsolescence.
Nope, can confirm 100%, they're plastic. I just tested the edge with a razor blade, 100% plastic, made before the modern day enshittification and planned obsolescence era.
Damn. I didn’t think they used plastic back in the day, I assumed it was a modern thing. Well. You know what they say about assume. Thx for the correction.
