EXPERIENCING BLURRY VISION? HERE'S WHY
Eye
The eye is the organ of sight. The two
eyeballs, protected within bony sockets called orbits and on the outside by the
eyelids, eyebrows, and tear film, are directly connected to the brain by the
optic nerves. Each eye is moved by six muscles, which are attached around the
eyeball. Light rays entering the the eye through the pupil are focused by the
cornea and lens to form an image on the retina. The retina contains millions of
light-sensitive cells, called rods and cones, which convert the image into a
pattern of nerve impulses. These impulses are transmitted along the optic nerve
to the brain. Information from the two optic nerves is processed in the brain
to produce a single coordinated image.
