In evaluation of the National Programme for Control of Blindness and Visual Impairment (NPCBVI), the National Blindness and Visual Impairment Survey India 2015–19 reported that the prevalence of blindness (visual acuity <3/60 in better eye) was approximately:
- A 0.36% ✓

- D 0.1%
Correct answer: A. 0.36%
Explanation
The National Blindness and Visual Impairment Survey India 2015–19 (published 2020) found a blindness prevalence (presenting VA <3/60 in better eye) of 0.36% among adults 50 years and above in the surveyed population. This represents significant progress from the 1.1% figure of 2001–02 and the 0.9% of 2007. Cataract remains the leading cause (~66.2%), followed by refractive errors, corneal disease, and posterior segment disorders. Understanding this current prevalence is important for monitoring NPCBVI progress toward the Vision 2020 goals.
