Subjects over 40 years old had a significantly higher prevalence of blindness and low vision. The causes leading to blindness and low vision were cataract (42.11%), corneal opacity (21.05%) and glaucoma (15.79%). CONCLUSION: The leading cause of blindness and low vision is cataract in Motuo county, therefore the surgical application in cases with cataract is the main measure in the treatment of blindness in the county.
