National Programme for Control of Blindness launched
India launches NPCB, the world's first national blindness control programme, focused on tackling cataract through mass surgical camps.
India has 8 million blind people, more than any country. Cataract causes 66 percent of India's blindness. Yet India also runs the world's highest-volume, most cost-effective cataract surgery.

India carries the world's largest absolute burden of blindness and visual impairment. The National Blindness and Visual Impairment Survey 2015 to 2019 estimated about 4.95 million blind people aged 50 and above and a total of 14 million people with moderate or worse visual impairment in that age group alone. Cataract drives 66.2 percent of blindness, followed by uncorrected refractive error and glaucoma. At the same time, India runs the world's largest cataract surgery programme. The National Programme for Control of Blindness performs over 65 lakh free cataract surgeries a year and Aravind Eye Care alone operates close to 5 lakh cataracts a year at one-tenth the cost of a Western hospital. The next chapter is harder. Diabetic retinopathy, glaucoma, age-related macular degeneration, and the rising childhood myopia tide demand a different kind of system, one that screens, follows up and counsels rather than only operates.
Cataract dominates Indian blindness for a mix of biological, social and system reasons. High lifetime ultraviolet exposure across north and central India, common nutritional deficiencies in childhood and adulthood, and a large diabetic population all speed up cataract formation by a decade compared with northern European populations. Cataract incidence is also unmasked by demography, since the over-50 population has crossed 30 crore. Yet biology is only half the story. Three system features explain why so many people who could see again remain blind. Outreach gaps mean many cataract patients in tribal and remote areas never reach a screening camp. Out-of-pocket cost still deters older women, particularly widows. And quality concerns push some patients to delay surgery until vision is almost gone. Aravind and LV Prasad have shown that high-volume, high-quality, cross-subsidised surgery at scale can deliver world-class outcomes, but the wider public network is still uneven across states.

India collects only 11 million units of blood annually against a need of 15 million. The O-negative shortage is acute, urban blood banks run on single-day reserves, and the rural gap is catastrophic.
India has fewer sports medicine doctors than many US college programs. Cricket and marathons grew fast; specialist care did not, so preventable injuries end careers early.

Micronutrient gaps hit rich and poor: anaemia stays high, vegetarians often lack B12, and urban adults lack vitamin D. Fortification and better diets can bend the curve if delivery improves.

Key statistics on Indian blindness and eye care:
Myth 1: Cataract should be allowed to ripen before surgery. Fact: Modern phacoemulsification and even high-volume manual small-incision surgery work best on a moderately mature cataract. Waiting for full opacification raises the risk of zonular weakness, longer surgery and worse final vision. The right time to operate is when vision starts affecting daily life, not after the patient is blind.
Myth 2: Wearing glasses makes eyes weaker. Fact: Glasses do not change the underlying biology of the eye. The right prescription lets a child or adult see and learn, and treating progressive myopia with low-dose atropine, outdoor time and proper screen breaks can slow progression. Not wearing glasses leads to amblyopia in children and falls in the elderly.
Myth 3: Eye drops for glaucoma can be stopped once pressure feels normal. Fact: Glaucoma is silent and pressure rises again the moment drops are stopped. Loss of peripheral vision is permanent. The drops are a lifelong commitment to keep the optic nerve safe, and stopping them mid-year is the most common reason glaucoma patients in India lose useful vision.
Take Rukmini Devi, a 68-year-old widow in a Madurai district village whose cataract surgery at the Aravind eye camp in 2024 took 12 minutes and cost her nothing. Within a week she returned to her work of sorting tamarind, regained her income and stopped depending on her daughter to walk to the toilet. Multiply Rukmini by 65 lakh surgeries every year and the dignity dividend is enormous. But there are also families like the Pawars in rural Maharashtra, whose 11-year-old son's progressive myopia went untreated for two years because the nearest optometrist was 35 km away. By the time they reached a specialist, he had begun to lag in school. The cost of poor vision is silent. Lancet Global Health 2023 estimated India loses around 3 lakh crore rupees a year in productivity to uncorrected vision and avoidable blindness. The fix is not new science. It is reach, follow-up and trust in the system that brings glasses, drops and a clean operating theatre within a half-day journey for every Indian.
The bigger meaning of India's eye care story is that high quality and high volume can co-exist when systems are designed for it. Aravind, LV Prasad and the NPCB network have shown that 1,000 to 2,500 rupees can buy a cataract operation that matches Western outcomes, and that cross-subsidy from paying patients can fund free care for the poorest. The long-term consequence is that India has restored sight to millions and exported its model from Africa to Latin America. But the next decade will not be a cataract decade alone. Diabetic retinopathy, glaucoma and childhood myopia all need ongoing follow-up, not a one-time surgery. The lesson is that India must now build the same scale for screening, optometry and chronic eye disease that it built for cataract camps. Telemedicine retinal imaging, salaried optometrists in every Block CHC and integration with diabetes clinics will decide whether India keeps sight from slipping away in the next generation.
