Something has shifted. After decades of restoring sight – one surgery, one pair of glasses, one village at a time, Seva has crossed a threshold and I want you to be the first to understand what that means.
The research coming out of Guatemala this year stopped me cold. When we gave coffee harvesters eyeglasses, productivity jumped 8% within days. Every dollar spent returned $30 in combined wages and farm income. That result didn’t come from a new technology or a capital campaign. It came from a systems approach we have been quietly perfecting for 47 years; the disciplined belief that if you build the right infrastructure, train the right people, and measure what actually matters, the returns compound in ways that surprise even us.
The study has a name only an academic could love: Refractive error correction and harvest worker productivity in the Guatemalan coffee sector: A quasi-experimental analysis. It’s a mouthful. For this newsletter let’s call it Glasses for Guatemalan Harvesters.
