Quick Answer. The sense of sight is important as it helps compensate for a loss of other senses, enables the differences between good and bad food to be distinguished, helps create impressions and find partners and helps ensure safety by perceiving signs of danger.
Sight, like the other senses is closely related to other parts of our anatomy. The eye is connected to the brain and dependent upon the brain to interpret what we see. How we see depends upon the transfer of light. Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
