Effect of Vision Centers on Access to Eye Care and Eye Health Outcomes

This cluster-randomized trial aims to evaluate the effect of vision centers on access to eye care and eye health outcomes in South Asia. The main questions it aims to answer are: 1. Do vision centers improve effective refractive error coverage? 2. Do vision centers increase eye care center utilization? 3. Do vision centers improve population visual acuity? Researchers will compare outcomes in communities randomized to immediate versus delayed establishment of a vision center. Outcomes will be assessed through population-based surveys at baseline and after two years as well as through hospital records collected throughout the study period.
