Refractive error correction among urban and rural school children using two self-adjustable spectacles.

Objective: Self-refracting spectacles (SRSs) have different optical and mechanical designs, which may affect the refractive outcome, depending on the experience of the end user. This study compared the performance of two SRS among children in Ghana.

Methods And Analysis: A cross-sectional study of two Alvarez variable-focus SRS designs was conducted.
