Human eye. Close-up view of a healthy,blue,human eye. The pupil (black,at centre) is surrounded by the blue iris. Around the iris the white of the eye is seen. This is known as the sclera,the tough outer coating of the eyeball. The eyelashes (black,at top & bottom) protect the eye from dust. The pupil and iris are covered by the cornea,a protective lens which also performs most of the focusing of light as it enters the eye. The eye is the organ of sight and consists of structures that focus an image on the retina,an area of light sensitive cells at the back of the eye | |
