We appreciate the interest of Galvis and associates in our work.1 It has been suggested that undercorrection of children's refractive error might retard myopia progression. Previous studies,2,3 limited by size, have generally not been consistent with this. We performed a post hoc analysis on data from our large trial of spectacle provision in China and found no evidence of worsening visual acuity (VA) among children randomized to receive glasses compared to controls. In fact, the final uncorrected VA of Treatment Group children was significantly better than that of controls.
