Asthenopia (eyestrain) in working children of gem-polishing industries

Abstract

Working children of gem-polishing units are exposed to poor illumination and improper workstations. Also processes require lot of visual and mental concentration for precision. This may result in eyestrain. The study included 432 exposed and 569 comparison group subjects. Self-reported eyestrain was recorded through personal interview. Eyestrain included symptoms like itching, burning, or irritated eyes; tired or heavy eyes; difficulty seeing clearly (including blurred or double vision); and headache. The study variables included age, gender, daily working hours, and duration of exposure. The prevalence of eyestrain in child labourers was 32.2%, which was significantly more than the comparison group subjects. Also, the working children of gem-polishing units were at 1.4 times higher risk of developing eyestrain. Age ³14 years and female gender were significantly associated with the eyestrain. The prevalence of eyestrain in child labourers was 32.2% and was associated with age ³14 years and female gender.
