Vision screening for fitness to work among school vehicle drivers: A cross-sectional study in Chiang-Rai, Thailand
Main Article Content
Abstract
This research was to examine the prevalence of visual functions for fitness to work; visual acuity, muscular balance, depth perception, and color perception, among school vehicle drivers. The cross-sectional study conducted in Chiang Rai Province, Thailand. 79 school vehicle drivers were participated. The self-administered questionnaire was executed in two sections; general characteristics and work experience. The vision screened was examined by Titmus V4, occupational model. The study begins with an examination of professional drivers' personal and occupational characteristics, followed by an examination of their visual function. The preponderance of the drivers were older men who were married and had completed secondary education, according to the findings. Overall, 14 of the 79 professional school vehicle drivers passed the criteria based on a visual job criterion that was the highest standard for those who worked with vehicles. The results showed that the visual acuity, which is the visual functions for fitness to work that most affects the fail criteria, largely distributed in the range of normal (fit to work) followed by mild visual impairment.
