Background: Dry-yam grinding like any other grinding process is usually associated with a lot of dust released into the atmosphere. Aims: This study examined and compared the eye complaints of dry-yam grinders and nongrinders, and evaluates the differences in their visual acuity (VA) test scores. This was with a view of determining influence of yam powder on the eye health of the grinders. Settings and Design: The study was conducted among grinders and nongrinders in two major markets in Ibadan. The study design was ex post facto. Materials and Methods: Participants were recruited using purposive sampling technique. Data were collected using interviewer-administered questionnaire and Snellen chart. Statistical Analysis Used: Frequency, mean, independent sample t-test, and Pearson’s moment correlation were use for statistical analyses. Results: Among 252 grinders and nongrinders who participated in the study, eye complaints such as foreign body in the eye (59.5% vs 29.0%) and headache (57.9% vs 37.3%) were more prevalent among grinders compared to nongrinders. More grinders had severe eye complaints (12.7% vs 3.2%). Mean eye complaints among the grinders were 6.92 ± 4.83 compared to 3.76 ± 4.37 among nongrinders. Dry-yam grinders exposed to yam powder had significantly more eye complaints and longer duration of complaints (P = 0.01). There was a weak positive linear correlation (0.167) between the duration of exposure to yam powder and severity of eye complaints. Grinders were observed to have a significantly lower VA on both the eyes (P = 0.01). Conclusion: Dry-yam grinders have more eye complaints than nongrinders. Grinders are encouraged to conform to safety dictates, such as using appropriate personal protective equipment and go for prompt eye assessment so that possible eye morbidity can be diagnosed and treated.
