RAAB is a rapid survey methodology that has been used to complete over 300 surveys of vision impairment and blindness to date. RAAB7 is a multi-year project together with Peek Vision (2018 – present) to deliver the 7th generation of the methodology.

Key new data inputs built into RAAB7 include uncorrected visual acuity (UCVA) measurements to calculate effective refractive error coverage (eREC), effective cataract surgical coverage (eCSC) and a disability module . Further research on enhancing data collection around near vision, other equity domains and specific eye health conditions is ongoing.

RAAB7 was launched in 2021 and a new RAAB site and repository is available at: www.raab.world
