This Call for Proposals (CFP), Integrated Refractive Error and Children's Eye Health Services through a National Approach, is intended to address the significant gap in access to refractive error services and children eye health services in low- and middle-income countries. The overall objective is to strengthen integrated, inclusive, and quality children's eye health services, while leveraging and building on existing opportunities and momentum to scale sustainable refractive error services for children and adults. The aim of the activity is to develop the necessary capacities, services, systems and policies to build towards a nationally owned program.
