Abstract
The objective of the study is to determine the effect of interchanging the background and foreground colors of the Duochrome test on the end point of subjective spherical refraction. The subjective endpoint being best corrected visual acuity, with optimal correction and subject’s ease in terms of brightness, sharpness and comfort with the correction. An Altman bland analysis revealed that there is no statistically and clinically significant difference by reversing the background and foregrounds.
