The metal your frames are made of is an alloy that contains copper, which turns green when it oxidizes. It's the same with cheap gold plated jewelry that turns your skin green.

TIL why my nose pads turned green! Thank you, knowledgeable Lemmster! ๐
So the answer to your other question is "Yes!" The Statue of Liberty is also green because it's made of copper. It was metallic when it was first installed in 1886, but had turned fully green within 20 years.
And just for the record, they fully expected it to happen and knew the old lady would look good in verdigris.
TIL! I always figued it was some kind of gross algae or bacteria. Really weirded me out.
Might not just be copper. Nickel is a common coating due to its corrosion resistance, but even that can oxidize over time and form a green oxide
No more calls; we have our winner.
Glasses frame is usually made of a type of copper called monel. Monel is a table metal and unreactive towards a lot of chemical. It is also skin friendly. The only downside is that it turns greenish when it gets rusty.
[edit] It's interesting that that article suggests a way to clean them--but the Costco optician just now said you can't really clean them. (They replaced them for no charge.)
I always thought it was moss, and that it was a sign I should go out more.
I think the green is from the locktight they use on the screws. But the glasses people blame the eyeglass wearer. It's a racket.
I've had this with cheap sunglasses that use copper screws to keep the pads on. The green is the copper oxidizing.
Does nobody actually wash their glasses regularly? I've never had a pair of glasses have their nose pads turn any color.
I rarely wash my glasses with soap and water, maybe once every month or two. I DO regularly wipe them with a cloth, usually my tshirt. My nose pads have never turned green in 60 years of wearing glasses.
I've had this with cheap sunglasses that use copper screws to keep the pads on. The green is the copper oxidizing. Cleaning them would only make it worse as you're just exposing the copper to water.
