VISION PHOTOCHEMISTRY

Shuchishrava Sharma*

ABSTRACT

Vision is no doubt the most important of all our senses. 40% of all the sensory information about the world comes to us through our eyes. But how do we see is one of the old scientific questions. The eye is the most extraordinary sensory organ. The wavelength response is 400-800 nm but its degree of sensitivity is such that the eye can clearly detect an object in light so dim to correspond to a light input over the retina of only about 1000 quanta per second. Retina contains a series of light sensitive cells known as Rods and Cones or Photoreceptor cells which respond to light and convert it into electrical impulses that create image. In this review, we discuss about the chemistry behind vision.
