Physiological Optics III

At the end of OPT 405 (Physiological Optics III) course, the students should be able to: 1. identify the steps involved in sensory vision; 2. describe the basic biochemical reactions/activities involved in vision processes; 3. explain the concept of visual thresholds and visual adaptation in relation to visual processing; 4. explain the processes involved in the perception of colours; 5. identify all the colour vision defects, their significance, and how they can be detected; 6. explain the principle involved in various colour vision tests and how to carry out the tests; 7. explain the basic electrical activities taking place in the retina and the visual pathway during visual processing; 8. discuss the physiology behind selected visual phenomena; 9. identify the various electrophysiological techniques and their applications; and 10. explain the concept of optical illusions, examples, and demonstration of each.

The photochemistry of vision. Sensory aspects of vision; thresholds and adaptation. The mechanisms of colour vision; colour vision defects, their detection and significance. Electrophysiology of the retina and visual pathway. Laboratory work is included.
