VISUAL CONSIDERATIONS Visual considerations should be given prior importance while designing an automobile as it has direct effects on its design and design is supposed to be a very crucial factor as undoubtedly it is the thing that decides whether people are going to like it and buy it or not. With increase in age, there is gradual loss of elasticity in almost all the muscles of the body including muscles of eyes. This reduction in elasticity of the eye muscles lead to inability of the person to focus on an object kept at a distance. This condition gets worse in the situation of dim light or excess light. Along with decreased muscle elasticity, the lens of the eye also become less transparent with increasing age as there is alteration…show more content…
(Retchin et al., 1988). 2. There is sharp decrease in the degrees of lateral peripheral vision with age. It reduces by nearly 17 degrees in the people above 65 (Burg 1968). Vision field loss 1. According to the data available, it is noted that the chances of developing visual field loss in the age of 16 yrs to 60 years is nearly 3 to 3.5 % which increases to nearly 13% for the people above 65 years of age.(Johnson and Keltner, 1983). 2. For individuals above the age of 65, the risk of development of visual field defects increase by nearly five times than the individuals below this age. (Johnson and Keltner, 1983). Glare/Night legibility 1. Due to degradation in quality of the lens with increasing age, the glare is impaired. Actually, the increase in opacity of the lens leads to inability of the eyes to view objects having less contrast especially in the dark. (Pulling et al., 1980). 2. It has been studied that inability to see anything in night for a fraction of second, also known as temporary visual impairment, caused by the bright headlight of the coming vehicle is more common in old people (Wolf, 1960; Pulling et al., 1980). It is also seen that the people who are already suffering from night blindness do not show any increased risk with age. In fact, there are chances that night vision impairment is less reported in such cases (McCloskey et al.,
