Visual Function in Professional Drivers In A Coastal Town of South India and Their Perceptions About Ocular Health

Abstract

Introduction: Good visual function is essential for drivers during driving. Many ocular conditions affect visual function.There is a need for the drivers to undergo ocular evaluation and awareness about eye health would motivate them to do so.Aim: To assess vision acuity, field of vision, colour vision, contrast and depth perception of drivers and to assess their knowledge, attitude and practice about ocular health. Materials and methods:A cross sectional, descriptive study was done among drivers for duration of six months.

Refractive error and abnormal stereopsis association with road traffic accidents in Saudi Arabian truck drivers

“…Regarding truck drivers’ visual functions, many studies from India have reported the visual functions of truck drivers,[ 18 19 20 21 ] but few are from other parts of the world. [ 22 ] In Indian individuals, Verma and Bharadwaj[ 18 ] reported a refractive error of 18.8% and color vision defect in 1.4% of the subjects.…”

“…Vidya et al . [ 20 ] found a refractive error in 37% of the subjects and none of the subjects had color vision defects. Similar to the Verma et al .’s study,[ 13 ] the current investigation found a prevalence of refractive error of 18.4%.…”

“…The prevalence of visual impairment found in the current study is higher than in some studies[ 5 10 14 ] and lower than in some studies. [ 19 20 ] This can be explained in part by the fact that the other studies used the best or pinhole-corrected VA for their analysis, whereas this study used the presenting VA. If this study had used corrected VA, the prevalence of visual impairment would have been lower because some visually impaired drivers would have been improved into the normal VA category.…”
