The Influence of Windshields with Lower Light Transmission in Driver's Vision During Night Driving

The influence of reduced light transmission of the windshield had been tested under night driving conditions with a driving simulator and the disadvantages of spectacles had been pointed out. When the luminuous density ratio of the objects on the road went to very low values the risk of accidents grew rapidly with low light transmission windshields or haze effects of already 1.2 % on normal tinted shields. The coincidation of low level light transmission and haze effects in the results shows a possibility to denominate limits for the use of aged windshields and no acceptance for the use of low light transmission windshields at least for spectacle wearing drivers.
