Nice folks to deal with - but how accurate is the beanie? Thanks for the tip on the cases!
The model is public knowledge; I'm happy to share it again here! The original glasses are Junior Gaultier model no. 58-0072 (not 68-0072 as you'll find in some threads). Unfortunately, that makes them designer glasses from circa 1993. Expensive even when new, produced in low runs for a short span of time over twenty years ago. They come in several color variations, including a sort of tortoise-shell opaque black. There's an amber variation which is translucent like these, and I believe a clear yellow frame which I've only seen with blue lenses with a small circular mirrored section. Sadly, the clear frames are rumored to be the rarest of them all and my long search would seem to confirm that. I've seen the wrong colors come up more than once.
The closest glasses on today's market are probably these guys:

No gold wire insert or hinges, but the shape looks good and they're clear untinted frames!
The original glasses from the film were sold at auction a couple years ago for $8,320 - you can check that listing out here:
