The effect of tinted lenses on mobility control / Nursyazwani Tawang

Background: The use of tinted lens started to become more widespread and not just
for fashion accessory or improvement of appearance but to reduce eyestrain in bright
light condition. There are many reasons behind the use of sunglass. Nowadays, people
are aware of the danger of ultraviolet (UV) light which may cause harm to the eyes.
The use of sunglass can reduce the amount of UV light enter the eyes and in addition
become act as protection from dust, or other hazard. To date, in Malaysia, the
sunglass prescription is not following the standard requirement for ideal sunglass.
Aim: The objective of this paper is to identify the effect of parameter, MC I, MC II,
MC III and MC IV in mobility control towards four different percentages, 0%, 25%,
50%, and 75% tinted lens intensity and to compare mobility control in vehicle
maneuver control with from previous study. Method: In this study, the vehicle
maneuver is used to predict the mobility control under different level of light
transmission. The light transmission is manipulate by the used of four different
percentage of tinted lens. Result: The effect of tinted lens is found that there is no
statistically significant on MC I, F(3, 60) = 0.928, p - 0.433, MC II, F(3, 51) = 0.386,
p - 0.763, MC III, F(3, 54) = 0.112, p = 0. .953, MC IV speed control when approach
traffic light F(3, 54) = 1.861, p = 0.147, and MC IV control on straight road regarding
steering control and (x,y) position F(3, 57) = 0.090, p = 0.965. Conclusion: Thus, the
use of sunglass is safe on day time driving as propose by the result of current study.
