RELATION OF VISUAL ACUITY AND CONTRAST SENSITIVITY UNDER NIGHTTIME DRIVING CONDITIONS

TEST DATA ARE REVIEWED TO ATTEMPT TO CORRELATE RELATIONSHIP OF VISUAL ACUITY AND THE ABILITY TO DETECT LOW-CONTRAST DIFFERENCES AT NIGHT. THE BEST COMBINATION FROM THE STANDPOINT OF NIGHTTIME DRIVING SAFETY IS EXCELLENT ACUITY PLUS EXCELLENT ABILITY TO DETECT LOW-CONTRAST DIFFERENCES AT NIGHT. THE AUTHOR CONTENDS THAT THE LATTER IS THE MORE IMPORTANT. IT IS CONCLUDED THAT MORE DATA ARE NEEDED.
