A common depiction of the sun in more lighthearted fare, such as children's and animated media, is that of a large yellow disc with rays perpetually coming out and a human face, often wearing sunglasses, which leads to the question of why the sun would need protection from its own rays. (Well, what other glasses would the sun wear than SUNglasses?) Plus, if your head emitted as much light as the sun does, you would probably need something to protect yourself from the harmful rays of... yourself.
