Effects upon color perception were studied using the Corning Medical Optics CPF lenses and the Younger Optics PLS lenses. Measurements were obtained using the Farnsworth 15-hue (D-15) color test. Color perception errors associated with the respective lenses were statistically analyzed. Comparisons of these individual lens errors were then made among all the lenses included in the study. All the lenses significantly altered color perception in some or all of the visible spectrum. In all cases, the Corning CPF lenses had either equal or lesser effects upon color perception errors than did the Younger PLS lenses.
