Evaluating Self-Refraction and Ready-Made Spectacles for Treatment of Uncorrected Refractive Error

open access: yesOphthalmic Epidemiology, 2018
Uncorrected refractive error is the leading cause of visual impairment worldwide and has significant quality of life and economic implications. Treatment with subjective refraction and custom-made spectacles requires expensive equipment and highly trained personnel. We examine several alternatives.Patients were taught to self-refract using two devices:
