Contrast Sensitivity Function and Low Vision

Abstract

The Canadian Association of Op­tometrists through its educational endowment fund recently provided the funds for a custom designed con­trast sensitivity function unit at the low vision clinic of the University of Waterloo. Its purpose is to enhance the capability of low vision clinicians to evaluate residual functional vi­sion of some low vision patients where conventional visual acuity ap­proaches fail to quantify any func­tional loss of vision.
