Called PROSPER the study affirms that eyeglasses have the potential to dramatically boost worker productivity worldwide. In India, providing tea pickers with corrective lenses improved worker productivity by 21.7 percent, with productivity increasing to almost 32 percent when vision correction was provided to workers over 50. This represents the largest ever recorded productivity increase from any health intervention. The randomized control trial offers the most compelling and definitive evidence to date linking eyeglasses and productivity. The research was a collaborative effort undertaken by VisionSpring, Clearly, Orbis, and Queens University Belfast.

2.5 billion people could see clearly to earn, learn and be safe, if they could acquire a pair of simple eyeglasses. Of these individuals, 624 million are visually impaired without this 700-year-old technology; and 70% just need a pair of over-the-counter reading glasses. These are the type of non-prescription glasses that can be purchased at a pharmacy in the US and Europe, and that VisionSpring can source for as little as $1.
The market is not meeting the needs of consumers earning fewer than $4 per day, and the cost of blurry vision is not just born by individuals. Uncorrected refractive erroriii is costing the global economy an estimated $227 billion with low-income countries disproportionately affected.
For low-income earners, eyeglasses are a simple, affordable tool that sustains productivity and earning power. Eyeglasses can prevent middle-aged workers from experiencing any drop-in efficiency and productivity associated with the eye’s natural aging. Without the ability to focus up close, mechanics, barbers, tailors, teachers, artisans, and many others whose work requires clear near vision, lose years of income earning potential.
