Ocular health status of Nigerian industrial workers.

In an ophthalmic survey of 3676 industrial workers in Kaduna, Nigeria, 395 industrial workers had ocular defects. The anterior segment of the eye was mainly affected. A wide spectrum of other eye diseases was seen. Ninety-two workers had poor vision in one or both eyes or had totally lost the vision in one eye. Although considerable morbidity, especially in the form of chronic conjunctivitis, resulted from mechanical irritation of the eyes in one factory, industrial accident resulted in loss of vision in only two workers.
