OBJECTIVES
This study was undertaken to investigate the relationship between color vision defects and occupational exposure to mixed organic solvents in women workers who were engaged in the shoe manufacturing industry.
METHODS
A total of 173 women workers were involved in this study, 85 of whom were exposed to mixed organic solvents and were defined as the exposed group, and 88 workers comprised the non-exposed control group. The patients were questioned as to their drinking history, the year in which they were exposed and whether they had eye symptoms of blurred vision, eye fatigue, and eye irritation. The exposed workers in the shoe manufacturing factory were engaged in 3 work areas which were pasting, trimming, and cleaning. Their Color vision was assessed using the Hahn's double 15 hue test under standard illumination and their current and cumulative exposure levels were measured.
RESULTS
The prevalence of color vision defect was 21.2% in the exposed group and 8.0% in the control group, and the blue-yellow defect was found to be 5.9 % in the exposed group. The logistic regression for the acquired dyschromatopsia and color confusion index showed that there were no variables that had significant relationships. Eye symptoms were more frequently developed in the exposed group.
CONCLUSIONS
There is a possibility of developing color vision defects when workers are exposed to mixed organic solvents. However, the results of the color confusion index showed that there was no significant relationship to the cumulative exposure level, because of the low exposure level and high occupational turn over rate of the workers. Because the workers in the present study were exposed to low level solvents it will be necessary to study workers exposed to higher levels of organic solvents.
