Reading glasses are easy to come by in Western countries. But getting a pair in the Global South can be a challenge. A new study shows the surprising benefits that a pair of specs can bring.
"Before, when I tried to cut vegetables and wanted to see if there were any insects or not, I couldn't see properly," Atker says, speaking through an interpreter."After the glasses, the average time that I take for each task has reduced significantly. And I can do more work ... I have this sense of independence."There's now data that suggests Atker's story is common. For the first time, researchers have directly linked glasses and income.
The focus of this study was on reading glasses for near vision. That's because fitting someone with distance glasses is like tailoring a custom-made suit, with careful measurements and adjustments. Reading glasses are akin to buying off the rack, with just a few strengths to choose between. This study's findings fit with past studies that link glasses to productivity. For example, Congdon was involved in a study, in India, whereThe villagers in the study worked in a wide range of professions: shopkeepers, farmers, craftspeople and weavers, for example. Only about a third of them were literate.
"Ophthalmologists and optometrists may be advising the government that they should tightly regulate access to these products strengthen their professions. They may see themselves as gatekeepers of quality," he says."I wouldn't be recommending that we just hand out distance glasses, but I do think that for near glasses that's a reasonable thing to do."
