The Impact Of Refractive Error Correction On Harvest Productivity In The Guatemalan Coffee Sector, Bryce C. Everett

Current literature is in agreement that interventions targeting those with uncorrected visual impairment can realize benefits in various sectors, with particular regard to agriculture. The design of this experiment attempts to derive the intent-to-treat (ITT) effect stemming from the provision of glasses to coffee harvesters in Guatemala.
