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 | |
