Objective refraction may be a feasible approach to increasing 22 eyeglass accessibility in low-resource settings. 23 ABSTACT 24 Aim 25 To assess the quality of eyeglass prescriptions provided by an affordable wavefront autorefractor 26 operated by a minimally-trained technician in a low-resource setting.
