Abstract

Background: Welders are at risk of developing dyschromatopsia, a color vision deficiency, due to occupational exposure, including welding arcs. This visual impairment can impact occupational safety and performance but has received limited attention in research.
Aim and Objective: This study aimed to investigate the prevalence and characteristics of defective color vision among welders exposed to welding arcs.
Materials and Methods: A cross-sectional study was conducted with 52 male welders working in various industries. Demographic and occupational data were collected through a questionnaire. Color vision assessment was performed using Ishihara and Farnsworth Munsell test. Welding exposure data were collected through self-reporting and workplace observations. Chi-square test was used for data analysis. A p-value of less than 0.05 was considered statistically significant.
Results: The prevalence of defective color vision among welders was 15.4%. Age, gender, years of experience, and types of welding performed did not significantly influence the prevalence. Welders in the age group of 31-40 years showed a higher prevalence. Inadequate use of eye protection was identified as a barrier to preventing color vision impairments.
Conclusion: Defective color vision is a prevalent occupational injury among welders exposed to welding arcs. The study underscores the importance of preventive measures, including proper eye protection and education programs, to reduce the risk of visual impairments and improve occupational safety. Further research is needed to understand the long-term consequences of welding arc exposure on color vision and its impact on worker performance.
