Abstract
Background: Industrial exposure to chemicals is a significant health concern, particularly within the textile industry where workers are in regular contact with potentially harmful substances. The retina, with its photoreceptor cells responsible for color vision and contrast sensitivity, is especially susceptible to damage from such exposure.
Objective: This study aims to assess the impact of chemical exposure on the color vision and contrast sensitivity of workers in the Five Star Textile Industry, drawing comparisons with previous research to better understand the occupational risks and requisite protective measures.
Methods: A cross-sectional, descriptive study was conducted on 100 workers with an age range of 20-50 years, examining 200 eyes. The research took place from January to June 2023, employing the Pelli-Robson chart and D-15 test for evaluating contrast sensitivity and color vision, respectively. Data were analyzed using the Pearson Chi-Square test and SPSS version 25.
Results: The study found a Pearson Chi-Square value of 31.4 for color vision in the right eye and 25.7 in the left, with a significance of 0.000 for both. Contrast sensitivity tests revealed a Pearson Chi-Square value of 44.2 for both eyes, with significance remaining at 0.000, indicating a strong correlation between chemical exposure and visual impairment.
Conclusion: The findings suggest a significant relationship between prolonged chemical exposure and visual function decline among textile workers, underlining the necessity for enhanced occupational health protocols and regular vision screening.
