Why are spectacles important in a country like India?
A recent study has shown that spectacles, the oldest wearable known today, are an invaluable accessory for the poor, working class. The study, conducted in a tea garden in Assam (India), was led by Nathan Congdon, a professor of ophthalmology at Queen’s University, Belfast.
The scientists assembled 751 tea-pickers aged over 40 years. They gave spectacles to half of the group. Over a period of 11 weeks, the productivity of those with glasses improved by 39%. For tea-pickers, higher productivity means more earnings.
In a country with a population of more than one billion, there are millions who are not able to achieve their productivity potential because their eyesight is not corrected. If that problem could be addressed, the productivity of the country as a whole could increase substantially.
The case is not peculiar to India; proper eye care hasn’t reached the needy in many other countries. Even in China, half of the people with uncorrected long sight do not use spectacles. This is either because of a social stigma that glasses make people ugly, or due to existing laws that prevent widespread sales of glasses.
