On addressing the burden of uncorrected refractive errors

open access: yesPhilippine Journal of Health Research and Development, 2023
Uncorrected or unaddressed refractive error (URE) is the leading cause of treatable visual impairment (VI) globally. A significant factor is the prohibitive costs of corrective options. The World Health Organization recently recommended the use of effective refractive error coverage (eREC) to determine the burden and management of URE. To increase eREC,
