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:
“The child thinks of growing old as an almost obscene calamity, which for some mysterious reason will never happen to itself. All who have passed the age of thirty are joyless grotesques, endlessly fussing about things of no importance and staying alive without, so far as the child can see, having anything to live for. Only child life is real life.”
—George Orwell (1903–1950)
“For what we call illusions are often, in truth, a wider vision of past and present realities—a willing movement of a man’s soul with the larger sweep of the world’s forces—a movement towards a more assured end than the chances of a single life.”
—George Eliot [Mary Ann (or Marian)
