Book excerpt: The WHO Vision and eye screening implementation handbook (VESIH) offers a step-by-step guidance for conducting vision and eye screenings in community and primary care settings. The evidence-based interventions are drawn from the WHO Package of eye care interventions and developed with a focus on delivering screenings easily, safely, and effectively in low- and low–intermediate-resource settings. The early identification through screenings ensures timely treatments and management to avoid vision impairment in high-risk populations, including newborns, pre-school children, school children, and older adults. To further support country approaches, the VESIH incorporates a section on the advantages and disadvantages of diverse vision and eye screening approaches. Additionally, various pathways for refraction and spectacles service delivery are outlined, along with actionable recommendations aimed at enhancing refractive error services. The VESIH serves as a comprehensive guide for effective vision screenings in diverse settings, contributing to WHO SPECS 2030, in particular, to improve access to refractive services.
