The
Problem: Damage
Glasses
are a part of everyday life in the developed world. We rely on them
for several of our critical activitiesreading and learning, working,
interacting with other people and operating vehicles. For the many in
the developing world who need glasses, these critical activities are
made difficult, impossible or dangerous. As a result, economic and personal
losses occur, totaling more than 75 billion dollars of damage annually.
For
educators the cost is enormous. Excluding the US and Europe, there are
600 million students worldwide. Between 5 and 10% of this student population
needs glasses in order to learn effectively. Without proper glasses, students
learn critical skills at a slower rate. Even students with only moderate
vision problems become disadvantaged, as discomfort while reading discourages
studying.
In the
workplace, the costs are even more severe. Nearly all workers over 40
years old have problems with near vision; those that do not have glasses
may be forced out of the labor market. Younger workers with vision problems
may never be able to become fully productive, limiting their income
potential. Those with jobs may find their productivity slower. If glasses
could provide only a 5% increase in productivity for the workers who
need glasses over $50BB in economic gain could be created.
