Question

Describe how vision occurs, include the anatomical structures from the outer eye to the location where light is perceived (hint-the brain).

Answer 1

• Light passes through the front of the eye (cornea) to the lens.
• The cornea and the lens help to focus the light rays onto the back of the eye (retina).
• The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
