How much does sight loss cost?
Productivity loss due to poor vision per year
This research highlights the economic impact of avoidable blindness and sight loss (ages 50-64) on productivity loss (in USD) across countries. Investing in eye health services, especially for working-age populations, can boost productivity and support economic development.

What progress are we making?
Eye care integration
This table presents key results from the 2030 In Sight Country Progress Survey, providing data on country-level progress toward eye health systems goals outlined in the 2030 In Sight strategy. This structured tracking of national-level indicators helps identify gaps and implementation challenges that require targeted intervention.

Economics
Schooling and economic loss
Schooling and economic loss from uncorrected refractive error in school children
This table shows the educational and economic impact of uncorrected refractive error (URE) in school children by country. The educational impact is significant, with tens of thousands of school years lost each year in many countries. Cost-effective interventions like vision screening and eyeglasses offer long-term benefits for individual earnings and national economic growth.

Effective coverage
Cataract
Effective cataract surgical coverage (eCSC)
This table presents key cataract surgery metrics: CSC, eCSC, and the relative quality gap. The gap between CSC and eCSC reflects opportunities to improve surgical quality and post-operative care.

Cataract
Cataract surgical rate (CSR)
Cataract surgical rate (CSR) is the number of cataract operations performed per million population annually. The CSR is a key indicator of a country’s capacity to address cataract-related blindness, and CSR metric helps identify countries needing increased surgical services to address cataract backlogs and reduce preventable blindness.

Cataract
Cataract surgery: average out of pocket cost
This table presents country-specific data on out-of-pocket costs for cataract surgery across different service delivery sectors. These cost differences can influence treatment-seeking behavior and ultimately affect cataract surgery uptake rates. Understanding these financial barriers is essential for developing targeted policies that expand affordable access to sight-restoring surgery for those most in need.

Refractive error
Effective refractive error coverage (eREC)
Effective refractive error coverage (eREC) is the proportion of people in need of refractive error services who have received services and have a good-quality outcome.
eREC data displayed is for the 6/12 threshold, crude prevalence for adults 50+.
