Objective To investigate the prevalence of blindness and low vision in Meixian County. Methods According to the principle of stratified random sampling and Blind grading of World Health Organization (WHO), 11327 cases of blindness and low vision were sampled from the county according to the sampling rate of 210%. Results The prevalence of binocular blindness and low vision were 0 47% (0 30% for males and 0 6 3% for females) and 0 89% (0 6 6% for males and 1 12% for females); 9%, 0 34% in the suburbs of Fucheng and 0 5 6% in the mountains. The prevalences of monocular blindness, binocular low vision and monocular low vision were 0 72%, 0 89% and 0 59%, respectively. The prevalence of ≥50 years old blind and low vision patients was significantly higher. Conclusions Blindness and low visual acuity are the most common cause of cataract in glaucoma, followed by glaucoma, refractive error, amblyopia and pterygium.
