WHO defines visual impairment as visual acuity of less than 6/18 and blindness when
visual acuity is less than 3/60. In 2020 it was estimated that there are 43.3 million people blind and 553
million had some degree of visual impairment. The number of people affected by blindness is estimated
to rise to 61.0 million by the year 2050. From the causes of VI and blindness, an estimated 50% are
either preventable or treatable. In Ethiopia the pooled prevalence of blindness was found to be 1.18%
with regional variations and the highest rate reported in SNNPR with a prevalence of 1.9%.
