VISUAL ACUITY AND TRAFFIC SAFETY

SEHLEISTUNG UND VERKEHRSSICHERHEIT

IN NORMAL DAYTIME TRAFFIC IT IS NOT THE ISSUING BUT THE PROCESSING OF OPTICAL INFORMATION WHICH CAUSES PROBLEMS; IN CONTRAST AT NIGHT THE INFORMATION PRESENTED IS REDUCED TO A FRACTION OF THAT OFFERED DURING THE DAYTIME. IN DRIVERS AGED 40 YEARS AND OVER, NIGHT VISION IS GRADUALLY REDUCED AND SENSITIVITY TO GLARE INCREASED. NIGHT MYOPIA ALSO PLAYS A PART WHICH IS INADEQUATELY TAKEN INTO ACCOUNT. IN DAYTIME TRAFFIC, PARTICULARLY ON LONG JOURNEYS, A 2.0 VISION HAS CONSIDERABLE SAFETY ADVANTAGES COMPARED WITH THE NORMALLY REQUIRED 1.0 OR ONLY 0.7 VISION. FOR THE VEHICLE DRIVER PROTANOPIA OR PROTANOMALY IS A GREATER HANDICAP THAN DEUTERANOPIA OR DEUTERANOMALY.
