A green windshield at night reduces acuity from 20/32 to 20/46, and combined with pink glasses to 20/60. Resolution thresholds decreased from 10 to 42 seconds of arc, so that a pair of objects that could be seen through a clear windshield at 100 feet decreased to 25 feet through the green. Other visual functions found "defective in night-driving conditions with tinted glass" were stereo acuity,...
