Objectives: To determine the magnitude and causes of avoidable blindness in 50 years and older population of Amran and Lahj governorates, Yemen. Materials and Methods: Using the RAAB manual, 78 clusters were randomly selected, 50 people aged of 50 ≥50 years were examined in each cluster. Visual acuity (VA) was measured with a tumbling "E" chart. Ophthalmologists examined people with <6/18 in either eye. A software program for RAAB was used for data collection and analysis. Results: In Amran and Lahj, 1789 (91.8%) and 1836 (94.3%) people were examined, respectively. The prevalence of blindness (VA < 3/60 in better eye, with available correction) in Amran was 9.33%, while in Lahj it was 10.84%. The principal cause of blindness was unoperated cataract in both governorates. The three main barriers to cataract surgery were unaware of treatment, destiny /God's will and cannot afford in both Amran and Lahj governorates. Conclusion: The prevalence of blindness, severe visual impairment and visual impairment in people aged ≥50 years in Amran and Lahj governorates were relatively higher than WHO's estimate in the sub region and the principal cause of blindness was untreated cataract in both governorates.
