These data gathered from RAAB surveys or published research studies provide the causes of different levels of sight loss for different countries. Most sight loss can be treated or prevented.

These data present the current status of elimination as a public health problem of two major neglected tropical diseases (NTDs) that cause preventable blindness: trachoma and onchocerciasis (river blindness).

These data show key cataract surgery metrics for the selected country, cataract surgical coverage (CSC) and effective cataract surgical coverage (eCSC). The gap between CSC and eCSC indicates opportunities for improving surgical quality and post-operative care.

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

These data show the average out of pocket cost for cataract surgery, as reported through a survey completed by a key respondent in each country.

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+.

This table presents key metrics on spectacle access and utilisation at country level. These measurements help identify gaps between vision correction needs and actual service delivery, highlighting opportunities for targeted interventions to improve access to appropriate eyewear and reduce preventable sight loss.

These data show the average out of pocket cost for good quality spectacles, as reported through a survey completed by a key respondent in each country.

This chart presents the Universal Health Coverage (UHC) service coverage index, which measures population access to essential health services across multiple dimensions. The index serves as a key benchmark for monitoring progress toward SDG Target 3.8, which aims to achieve universal health coverage for all.

Eye health commitments are critical for meeting the goals of 2030 In Sight Strategy, including commitments made by diverse stakeholders. Strategic commitments are essential for translating goals into concrete action, representing one of the first steps toward sustainable improvements in eye health services.

This table maps key policy and regulatory frameworks that impact spectacle access at country level. These system-level factors can substantially influence affordability, availability, and quality of vision correction services.

This table provides data on the ratification status for three major United Nations human rights conventions that are relevant to eye health and vision care access at the country level for vulnerable populations.

These data demonstrate the progress towards the eye health systems goals of the 2030 In Sight strategy, as reported through a survey completed by a key respondent in each country.

This chart shows the ophthalmic human resources at country level. The workforce density information is vital for understanding service delivery capacity, identifying personnel shortages, and informing health workforce planning to achieve sufficient coverage for population needs.

Two key workforce indicators related to vision care at the country level. This global dataset helps identify workforce capacity gaps that may impede access to essential vision services and assistive technologies.

RAAB is a well-established population-based eye health survey. It assesses the prevalence and causes of vision loss and blindness among people aged 50 years+. Data from RAAB surveys are vital to generate vision loss estimates calculated by the Vision Loss Expert Group on the Vision Atlas. This table shows RAAB surveys since 2000.
