Blog post #5 The Eye (how light percieves through the eye)

Eyes are the part of are body that enable us to see. The light first passes through the pupil which is the black dot in the center of the eye ball. The iris controls the pupil opening. For examply when your eyes look at a bright light your pupil will shrink in size, but when in dark areas your pupil will dilate past its normal size which enables us to see some what in the dark. Our lens which sits right behing the pupil/iris helps focus images which are percieved by the retina.  The retina sits in the back of the eye between the aqueous humor. The retina is a very important part of the eye which contains rods and cones which are our receptors that process the visual information. The rods detect black, white, and gray and helps our peripheral vision. Cones are in the center and detect color sensations. Next in line is the optic nerve, which carries the neural impulses from the retina to the brain.
