Abstract
This study examined the effect of Perceived Contrast Enhancing (PCE) lens technology on traffic signal detection and recognition for color-normal and color-deficient observers compared to a neutral density lens. Eighteen color-normal and eighteen color-deficient participants performed a visual-motor task while wearing two different PCE lenses with specific spectral transmissions as well as a neutral-density lens. At random intervals, simulated traffic light signals were presented 5° to the right and left of the participant’s focal point, to which participants identified signal color using a three-button input device. Response time and error rate were recorded. We found that lens tint did not have a significant main effect on response time and error rate. The data collected in this study lends considerable evidence to the assumption that PCE lenses will not impair driving.
