Importance For Vision
Looking at one's surrounding environment, the vast majority of visible objects are seen primarily by diffuse reflection from their surface. This holds with few exceptions, such as glass, reflective liquids, polished or smooth metals, glossy objects, and objects that themselves emit light: the Sun, lamps, and computer screens (which, however, emit diffuse light). Outdoors it is the same, with perhaps the exception of a transparent water stream or of the iridescent colors of a beetle. Additionally, Rayleigh scattering is responsible for the blue color of the sky, and Mie scattering for the white color of the water droplets of clouds.
Light scattered from the surfaces of objects is by far the primary light which humans visually observe.

Famous quotes containing the words importance and/or vision:
“I can never bring you to realize the importance of sleeves, the suggestiveness of thumb-nails, or the great issues that may hang from a boot-lace.”
—Sir Arthur Conan Doyle (1859–1930)
“I wish I could take back some of the things I said and some of the things I did. But in the bigger picture, I don’t feel that it was violent and terrible. I feel like it was primarily—obviously not completely—moral, based on a vision that the government should be better, and that people could be better, and that democracy should be real.”
—Bernardine Dohrn (b. 1942)
