Black Lens

Black Lenses are an item added in the 1.0.3 patch, and are dropped by Demon Eyes and have about a 1 in 150 chance of being dropped. They are used to craft Sunglasses out of 2 Black Lenses, and nothing else. Blood Moons are useful for collecting these, as Demon Eyes spawn more frequently during them. They will also, when equipped, make the sun wear sunglasses.
