Lens hood are primarily designed to stop light coming into the lens
at extreme angles and being reflected inside the lens. This can lower
the contrast of the image. Lens hoods also have two other very practical
uses. Since the end of the lens is extended, you also get the added
benefit of some extra protection from accidental impact, and also help
to keep your fingers away from the front of the lens.
