The human eye

Close up image of the human eye.

The eye is our collector of light, giving us sight. Its delicate structures enable entering light energy to be converted to electrochemical energy. This stimulates the visual centres in the brain, giving us the sensation of seeing. Sight is one of five human senses that act as ‘gatekeepers’ of our bodies.
