Vision 2020 is a global initiative to eliminate preventable blindness by 2020. It targets diseases like cataract, refractive errors, childhood blindness, trachoma, and onchocerciasis globally. In India, it also focuses on glaucoma, corneal opacity, and diabetic retinopathy. The program implements a 4-tier system of primary vision centers, secondary service centers, tertiary training centers, and centers of excellence. Onchocerciasis is not included for India since it is not prevalent, and epidemic conjunctivitis is excluded globally and nationally. Cataract is the major cause of blindness in India. School screening programs help identify and refer children who cannot read certain lines to community health centers
