The document discusses the anatomy and physiology of the visual system and eye. It describes the eye as a spherical organ that uses various anatomical structures like the retina, choroid, lens, and cornea to form images. Light enters the eye and strikes the retina, where photoreceptors convert it into neural signals that are sent to the brain for processing and interpretation of the visual environment. The document outlines the major anatomical components of the eyeball and its accessory structures that work together to enable vision.

1. Eye A & PEye A & P

2. VisionVision
• Aka. visual perception
• The ability to interpret the
surrounding environment by
processing information that is
contained in visible light.
• We rely on vision more than any
other special sense

3. Visual SystemVisual System
• The various anatomical &
physiological components
collectively involved in vision
• Allows individuals to assimilate
information from their
surroundings.

4. The EyeThe Eye
• The eyes are sophisticated visual instruments!
• Roughly spherical
• Diameter ~2.5 cm
• Weight ~ 8 g
