Landmark Study

Proves and Quantifies Impact on Worker's Productivity

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.

See to Earn

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.

Glasses and Socio-Economic Development

A trial of Indian tea pickers, has shown that the provision of glasses improved their productivity by 21.7 per cent – and for those aged over 50 the increase was 31.6 per cent.

This represents the largest ever recorded productivity increase from any health intervention.

The findings – in a study called PROSPER [PROductivity Study of Presbyopia Elimination in Rural-dwellers], is the first trial to show a link between clear vision and work performance. A collaborative effort between Clearly, Orbis International and VisionSpring, the study offers the most compelling evidence to-date of the incredible impact vision correction has on productivity among low-income workers in an agricultural setting.

The trial was carried out over a period of three months in tea-plantations in Assam, India, with reading glasses given to 750 mostly-female Indian tea pickers, aged between 40 – 50 +years. The daily weight of tea picked increased by 5.25 kilogrammes a day (21.7%) overall when compared to controls over a three-month period, with the largest increase seen in those over 50, with an increase of 31.6 %. Nearly 90% of workers were still wearing their glasses by the end of the study, and virtually all were willing to pay to replace them if needed—a sure sign of how much the glasses were valued.
