Spectacle lenses with highly aspherical lenslets for slowing axial elongation and refractive change in low-hyperopic Chinese children: A randomized controlled trial

Spectacle lenses with highly aspherical lenslets (HAL) have been shown to effectively retard myopia progression in myopic children. This study aimed to investigate the impact of spectacle lenses with HAL on refractive and axial length (AL) changes in Chinese children with low amount of hyperopia.
