Module Overview

Physiology of Vision 2

This core module develops scientific knowledge relating to the neurological and perceptual processes of visual function with particular emphasis on how individuals assimilate and process information from their surroundings. It provides a clear understanding of the psychophysics of the visual processes, helping students become familiar with clinical psychophysical techniques and tests, linking theory with clinical skills practiced in primary eye care (PEC) clinics 1 and 2. This module further develops student’s understanding of developing and ageing of vision. Students’ competency in assessing colour vision and communication skills will also be developed. through scenario based learning (SBL).
