Available in PDF, EPUB and Kindle. Book excerpt: A laboratory study investigated the effects on night vision of windshield transmittance and light-scattering properties in relation to the effects of reduced contrast, glare, night myopia, and age. Three groups of subjects included: (1) ten elder drivers, (2) ten younger drivers who were susceptible to low levels of night myopia, and (3) ten younger drivers who were not susceptible to night myopia. Visual acuity of all subjects was measured for high- and low-contrast targets viewed through five windshields with and without glare that simulated opposing low-beam headlights at 50 m distance. To assess night myopia, visual accommodation of younger subjects was measured objectively under each of the ten windshiled-by-glare conditions while they viewed four realistic low-luminance targets. The transmittance of three clean windshields, with different tints and rake angles (ranging from 45° to 75° from the vertical) varied from 0.86 to 0.43. Two additional conditions were created by mounting a dirty windshield at rake angles of 45° and 75°, which produced light transmittances similar to two of the clean windshileds but now with a higher degree of light scatter. The main results are as follows: (1) Reduced transmittance of clean glass elevated low-contrast resolution thresholds by 0.09 log units, but had no effect on high-contrast thresholds. (2) Light-scatter of dirty windshields elevated low-contrast thresholds to unmeasurable leves. (3) Glare elevated low-contrast threshold by 0.18 log units. (4) Resolution thresholds were 0.28 log units higher for low-contrast than for high-contrast targets. (5) Thresholds for low-contrast targets were 0.31 log units higher for elder than for younger subjets. (6) Tests of accommodation showed significant increases of night myopia with glare and reduced target luminance, as well as a tendency toward greater night myopia for higher luminance targets with the dirty windshileds as compared with the clean windshield...

Download or read book Vision in Vehicles IV written by I.D. Brown and published by North Holland. This book was released on 1993 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains contributions illuminating much of the current research occurring in the area of visual perception. It encompasses all aspects of vision and its relationship to vehicle design, including both the internal and external design of the vehicle as well as the perceptual and cognitive limitations of the vehicle controller. Issues specifically related to the vision of the driver are initially addressed and the problems of vehicle glazing and light transmission are considered. The major topics of visual perception and vehicle control are covered in three related chapters encompassing: collision avoidance, vehicle signalling systems and the acquisition of visual information. Moving on to the external environment and its relationship to vision, traffic signs are discussed. Approaches to the measurement and modelling of driver behaviour are dealt with and the area of telerobotic control of vehicles is considered. In-vehicle displays are covered in two related chapters addressing issues of visual workload and effects of display type. It is hoped that the book, contributed to by experts from a diverse range of disciplines, including optometrists, psychologists, physiologists, human factors specialists and engineers, will stimulate the progression of research in this area, as effectively as the preceding volumes did.
