Effect of Dust Exposure on Eye Defects of Ricemill Workers In Abakiliki Ebonyi State

In Nigeria's rice milling sector, particularly in Ebonyi State, workers are exposed to severe occupational health hazards due to insufficient use of safety measures.

From this present study, the distribution and correlation of conditions associated to visual acuity as against the various years (1-3 years, 4-6 years, 7-9 years and 10 years and above). In Usage Of Eye Protective Wear (UOEPW), Availability of Dust Control Measures (AODCM), How Often Do You Go For Eye Checkup (HODYGFEC), Do You Experience Any Eye Symptom (DYEAOTOS) and Colour Blind parametres respectively shows higher values in those under the work duration of 1-3 years when compared to other years.
