Seeing is Learning

REAP Project

International studies put the economic cost of uncorrected vision at billions of dollars per year worldwide.

What is the cost to China’s children? Before 2012, no one knew. Not the Ministry of Health or the Center for Disease Control, not researchers in academia.

In 2012 REAP carried out the largest vision care policy experiment ever performed in China.

The goals of the study were simple:                     

  • Measure the prevalence of poor vision in rural and migrant areas of China
  • Measure the impact of poor vision on education
  • Determine effective ways to get students to acquire and wear glasses
  • Develop strategies for policy makers to bring vision care into the national health care agenda

Since then our revealed the extent of the problem: there are tens of millions of children in rural and migrant areas of China that have uncorrected vision, and the condition is having a serious impact on their education.

Let’s take a closer look:

      > Access to Vision Care: Rural vs. Urban
      > Quality of Rural Refractionists
