Description:

The Understanding the Physiology of the Visual System learning program is designed as an introduction to the physiology of the eyes, including their light-sensitive cells and accessory structures. The program begins by exploring the optical components of the eye that bend light to focus images, and the cellular machinery that encodes this visual information into nerve impulses. It then explains how eye movements are coordinated to keep track of visual targets to produce 3-dimensional vision. Finally, it describes how the brain pieces this complex visual information together to yield a coherent perception of the world.

Upon completion of this learning program, you will be able to:

  • Explain the visual optics of refraction, accommodation, and dilation.
  • Explain the function of photoreceptors and their photopigments.
  • Explain the tricolor mechanism of vision.
  • List and describe the different types of eye movements.
  • Explain binocular vision and its properties.
  • Explain image processing in the retina and visual cortex.
