Intro to Human Eye Anatomy & Physiology

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.
