Increasingly, automobile designers are utilizing tinted glasses for concept cars, specialty models, or to differentiate their vehicles. The objective of this study was to assess whether alternating different tinted windshields would affect aging drivers' visual acuity and glare response. Two commercially available windshields (bluish and greenish with same transmittance) were compared. The tests of visual acuity, contrast threshold, glare detection, and discomfort glare rating were performed to address the windshield effects on both the older and younger populations. Fourteen elderly and seven young individuals participated in the study. The results indicated that alternating between the tested tinted windshields would not affect drivers' visual performance for both age groups. The implications and future research are discussed.
