Why do the nose pads on my glasses turn green--as opposed to some other color?
Do I have more in common with the Statue of Liberty than I might have thought? 🤔

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.
