Effects of Various Quality Polarized Lenses on Color Vision, Stereopsis, VisualAcuity, and Contrast Sensitivity

摘要

Polarized sunglasses are commonly used for glare reduction in tasks such asdriving and in outdoor recreation such as fishing. These glasses are produced by many manufacturers and offered at a widely variable expense to the consumer. Studies of visual performance changes from plain tinted sunglasses including visual acuity, contrast sensitivity, stereopsis, and color discrimination have been completed in the past, but these factors have not been studied with tinted polarized lenses. In this study, three groups of polarized sunglasses were assembled based on relative retail prices. The results of this study indicate that tinted polarized lenses affect the same chances that plain tinted lenses do, and the least expensive lenses were found to perform as well or better than the more expensive lenses in these four visual performance categories.
