Sight loss averted by 2030

This investment in eye health would dramatically reduce the number of people with sight loss in Guinea by 2030 and set the path for further declines by 2050.

The biggest early gains come from addressing presbyopia through cost-effective screening and ready-made near glasses, while reductions in distance vision loss will become increasingly important beyond 2030.

Accelerators in eye care needed in Guinea

Our research has identified six key accelerator interventions which can help fight against sight loss and deliver huge productivity benefits back to countries by 2030

Select each accelerator intervention for more detail and recommended scale up over time.

Early detection through screenings in the community

Many people—especially in rural and vulnerable areas—miss out on eye care because no one checks their vision. Screening is simple, low-cost, and can be done by trained community members.

Our plan follows successful global programs by rapidly expanding screening to reach underserved groups and strengthen the eyecare system’s sustainability.
