Reindeer can see ultraviolet light

It has recently been shown that reindeer are able to see ultraviolet light. This is to prevent them from having what is called snow blindness. Snow blindness occurs when our eyes' lenses absorb UV light, which causes a temporary blindness. This was shown not to be a problem with reindeer because they are able to see ultraviolet light, so it isn't absorbed by their lenses. This prevents snow blindness and allows them to see even in the worst of conditions.

This is a very interesting discovery. Ultraviolet light is not within the visible light spectrum, so I assumed that animals in general, not just humans, couldn't see outside of the visible spectrum. I don't know that this discovery will lead to any further knowledge or exploration in vision of other animals, but it was interesting to read about. I am not sure if this test has been performed on other animals that live in the arctic, but it would be good if we did. I am glad I read this article, it was good.
