Old People in Assam Couldn't Read the Deposit Form. So the Post Office Started Testing Eyes

Five post offices in Assam, India, have screened nearly 9,000 people and handed out free reading glasses, most of them to first-time wearers. Why the post office works as a clinic, what a trial in Assam's tea gardens found, and what the pilot has not shown yet.

Sangita Kalita used to teach school. These days she sits at a kiosk inside the Rangia post office in Assam, in India's north-east, and keeps an eye on the counter. When a customer is struggling with a deposit slip, she walks over.

"A lot of old people come in who are not even able to fill out the deposit form," she told NPR in July. The test she offers takes a few minutes and uses a spiral-bound book of printed lines in shrinking sizes. If it shows the person needs reading glasses, they leave with a pair. They do not pay for it.

Rangia is one of five post offices in Assam where the nonprofit VisionSpring has run eye screening since December 2025, in partnership with India Post. The postmaster there, Babul Boro, says more than a thousand people have come in for a test since the start. Another of the five is in Baihata, about 35 kilometres from the state capital. Bandana Devi, an accredited social eye care worker on the project, says she alone has seen over 3,000 people. "People here suffer from short-sightedness and vision problems," she told Scroll. "Many are happy after coming here."

A pair of glasses, and a daughter's exam results

Anjali Deka is 47 and runs a tea stall. Her first pair of glasses came from the post office. "Since I started wearing them, life has changed so much," she said. "I am able to help my children with their homework, and one of them has got over 97% in her exams." A local priest, Romesh Chandra Sharma, says his vision had been dipping for a while and things looked blurry. Now he can read his religious texts again.

Neither of them had an eye problem that needed a surgeon. They had presbyopia, the stiffening of the eye's lens that starts for almost everyone somewhere in their forties and makes small print swim. The fix has been known for about seven hundred years and costs a few dollars. The World Health Organization still counts more than 800 million people living with it uncorrected, and says that in many low-income countries fewer than one in four people who need glasses have them.

The Assam figures show how wide that gap is at ground level. By May, according to VisionSpring, more than 5,000 people had been screened in the five post offices, and about 80 per cent of those who got glasses had never owned a pair. By July the count was close to 9,000. Of those, 6,421, around 72 per cent, were found to have presbyopia and given glasses, and 82 per cent were first-time wearers. The typical household the project reached earns about 7,000 rupees a month, a little under 80 US dollars, and 41 per cent live on less than 5,000.

"The fact that 80% were first-time wearers indicates that there was no screening or program for eye health in the area," Shweta Verma, deputy director of VisionSpring India, told NPR.

Why a post office

The idea came from Geneva. In May 2025 the WHO and the Universal Postal Union signed an agreement there to try delivering near-vision glasses through postal networks, with a joint plan running to 2027. It hangs off a WHO initiative called SPECS 2030, launched a year earlier, which is meant to push up the share of people with refractive errors who actually get corrected. The arithmetic behind the idea is simple: there are roughly 680,000 post offices in the world, and about 150,000 of them belong to India Post, most in rural areas.

Anshu Taneja, VisionSpring India's managing director, put the logic in one sentence to Scroll. "We chose post offices because they are the most trusted address across India. People in Assam may have never seen an eye doctor, but they have been to their post offices several times."

A clinic asks people to make a trip, and to decide first that blurry print is a medical problem rather than just age. The post office asks for nothing extra. They were coming anyway, with letters, parcels and savings deposits, and the deposit form turns out to be a decent screening test in its own right. "People come here for all kinds of postal work, and now they are also coming here to have their eyesight checked and get their glasses," says Putesh Kumar Deka, the postmaster at Baihata.

We have written about the same principle from two other angles. In Afghanistan, the distance to a clinic turned out to be only half the problem for pregnant women, as we reported in Eighty-Two Percent Can Walk to the Clinic. That Was the Easy Half.. In Nairobi, a library started serving lunch once staff understood why children kept leaving at noon. Services that stick tend to be built into places people already trust.

What a pair of glasses is worth

Assam has a peculiar claim here, because the best evidence on reading glasses and income was gathered in its tea gardens.

In 2017 a team including P. A. Reddy and Nathan Congdon ran a randomised trial called PROSPER among tea pickers aged 40 and over. The workers' pay was tied to how much they picked, and spotting the right two leaves and a bud is close work. Of 751 workers with presbyopia, none of whom owned glasses, half got a pair straight away and the other half at the end of the study. Over eleven weeks, the group with glasses went from 25.0 to 34.8 kilograms picked per day. The control group improved too, from 26.0 to 30.6. The difference between the two, 5.25 kilograms a day, came to a 21.7 per cent rise in productivity. Older workers gained more. The glasses, including delivery, cost 10.20 US dollars per person, and by the end 84.5 per cent of the workers were still wearing them. The results were published in The Lancet Global Health in 2018.

The WHO puts the global cost of lost productivity from vision impairment at 411 billion US dollars a year.

What the pilot has not shown yet

The screening figures come from VisionSpring, which runs the programme and has a stake in how it looks. No one outside has published an evaluation of the post office pilot. It is also worth knowing that two of the PROSPER authors were VisionSpring's founder, Jordan Kassalow, and its current chief executive, Ella Gudwin. The trial was registered, randomised and peer-reviewed, and its design protects it well. Still, the organisation citing the study helped produce it. And PROSPER measured eleven weeks of tea picking, not years of income.

The post office model only handles one problem. Ready-made reading glasses correct presbyopia. People who need distance glasses, or who have cataracts or glaucoma, need an eye doctor. Neither Scroll nor NPR describes how those people are referred on from the post office, and that is the question to ask before the model is copied elsewhere.

Then there is the money. The pilot was due to end this month. Gudwin told NPR that VisionSpring would go through the data and look at funding before deciding whether to continue or expand. Scroll reports that the partners are considering an incentive or a paid model per pair of glasses dispensed. For households on 5,000 rupees a month, whether that pair stays free may decide who gets one. Clement Songate, who works on the project, points out that tea workers are an obvious group to reach, since some tea gardens already have a post office nearby.

Postal workers doing more than post is not a new idea. Elisabeth Rosenthal, a physician and writer at KFF Health News, reminded NPR that in France letter carriers can, for a small fee, stop in on elderly people and check whether there is food in the house. Japan has something similar. Assam's version is smaller and more specific: a trained woman at a kiosk, a spiral-bound book, and a box of reading glasses a few steps from the savings counter.

Babul Boro, the postmaster in Rangia, wants it to stay. He says the eye tests bring people through his door.
