Occupational Hazards, Associated Ocular Morbidities and Impact of Refractive Safety Eyewear among Agriculture Workers in India - A Two State Study.

Context: Agriculture is one of the occupations with the highest risk of injuries and fatalities but the farmers are ignorant about eye care and eye safety.

Aim: The current study aims at understanding the occupational hazard and ocular morbidities associated with agriculture and the effect of safety eyewear.

Settings and design: Multicenteric, cross-sectional, observational study was conducted in two states of India: Tamil Nadu and Karnataka. Subjects were agriculture workers recruited by convenience sampling.

Methods and material: The study was done in three phases: Phase 1: Visual task analysis (VTA), Phase 2: Comprehensive eye examination, and Phase 3: Spectacle compliance assessment. The Standard of Living Index scale was administered to assess the socioeconomic status of the participants.

Statistical analysis used: Descriptive statistics and logistic regression.

Results: A study involving 276 workers (39.4% male, 65.2% female) found that VTA agricultural tasks were visually less demanding but hazardous, carrying the risk of ocular and nonocular injuries. Ocular injuries accounted for 9.4% (26 cases), while nonocular injuries accounted for 9.8% (27 cases). Spectacle compliance assessment revealed that 91.8% (157 out of 171 workers) reported improved visual comfort, reduced dust exposure, and enhanced safety with safety eyewear.

Conclusions: This study illustrates numerous types of hazards associated with the occupation of farming. The study population had a 9.4% prevalence of ocular injuries. Refractive safety eyewear was reported to improve worker visual comfort.
