Research informs our way forward and puts the need for and impact of vision care access in context. Current focus areas include:

  • Impact of vision correction on academic outcomes in the US and China
  • Role of vision care in health system strengthening in The Gambia
  • Measuring awareness, physical access, and affordability of sustainable programs


“Bringing the Vision Care Crisis into Focus” (Research partner: Deloitte)

Key takeaways:
– 1.1 billion, or 1 in 7, people worldwide need glasses but do not have access to them
– Sub-Saharan Africa and Southeast Asia are the regions most affected, but lack of access is a problem that spans all age, gender and geographies

“Effect of providing free glasses on children’s educational outcomes in China: cluster randomized controlled trial” (Research partner: Stanford Rural Education Action Program)
