Module Overview

Physiology of Vision 1

This core module develops scientific knowledge relating to understanding the psycho-physics of the visual processes and the processes of visual function. Students will become familiar with clinical psycho-physical techniques and tests. Students will gain an understanding of normal colour discrimination and types and characteristics of colour vision defects.
