This is usually due to oxidation caused by the combination of nickel with the natural oils in the skin. Your nose is usually the oily part of your body. The oil in the nose mixes with sweat and then oxidizes the metal. Glass frames are usually made of a kind of copper called Monel. Monel is an easily corroded metal that does not react to many chemicals. It's skin-friendly. The only downside is that it turns green when it rusts.
