VISION 2020: The Right to Sight lists refractive errors, alongside cataracts, trachoma, onchocerciasis and childhood blindness, among eye conditions whose prevention and elimination can yield substantial socio-economic and educational developments worldwide.
Reported studies reveal considerable geographic variations in refractive errors, yet the distribution and variation of refractive error prevalence in different populations and age, gender and race sub-groups remains largely unknown. The persistent limitations and difficulties in reporting refractive errors in peer-reviewed circles are based on definitions of refractive errors, limited representation in studied populations, variable demographics and non-uniform refractive techniques.
RESC gathers data essential to determining the magnitude and public health significance of refractive errors in children of different ethnic origins. The data are crucial in improving the delivery and output of current refractive services, and establishing new services in underserved regions worldwide.
WOF has funded RESC projects.
