Caption

Refraction. Computer artwork showing the refraction of light beams through a biconcave lens. Light changes direction, or is refracted, when it meets a different transparent medium such as a lens. A biconcave lens causes light beams to diverge. It is used to correct myopia (short- sightedness), a condition in which light is focused before it reaches the retina.
