describe how light moves from outside the eye to the fovea centralis. Name all structures and
fluids it passes through and how it is refracted to the retina.
Solution
FUNCTIONING OF AN HUMAN EYE.
Human eye acts as a camera.Eye adjusts amount of light it lets in,focuses the objecs near and far
and produces images which is transmitted to the brain.
Light enters the trough cornea which acts like lens. The iris of the eye acts as a diaphram
controlling the amount of light which enters the eye and the size of the pupil is adjusted which
acts as an aperture. Then the light travels through viterous humor, a clear gel like fluid in the
middle eye, Then the light travels to the retina a sensitive inner lining of the eye which acts as
camera film and converts optical image into electronic signals. The image formed in thr retina is
upside down ,The optic nerve transmits signals to the visual cortex of the brain which flips the
image right side up and creats one complete image..
