Introducing RAAB7

The new generation of Rapid Assessment of Avoidable Blindness eye health survey.

A new and expanded version of the Rapid Assessment of Avoidable Blindness (RAAB) survey has officially launched, following extensive development and testing with leading eye health sector organisations. RAAB7 is delivered digitally using bespoke technology.  It enables faster, more accurate and more insightful data collection and analysis for effective eye health planning.

High-quality data is vital to understand the needs of a population in order to design and evaluate impactful eye health programmes to prevent vision loss. RAAB is a well-established population-based eye health survey which is used to assess the prevalence and causes of vision impairment and blindness among people aged 50 years and older, as well as recording priority eye care service indicators. The latest version (RAAB7) replaces its predecessor (RAAB6) and provides enhanced functionality and greater efficiencies across multiple stages of the survey.
