Spectacle lenses containing highly aspherical lenslets have been shown to slow myopia progression. Chinese Researchers of this study found that 95% of children who wore anti-myopia glasses experienced myopia progression of less than 2.50D. 

Over five years, HAL spectacles reduced the rate of myopia progression and axial elongation, preventing the equivalent of three years of myopia progression and axial elongation. Long-term wear of highly aspherical lenslets could significantly reduce the incidence of high myopia.

Researchers concluded: “Therefore, long-term wear of highly aspherical lenslets eyeglass lenses could significantly reduce the incidence of high myopia.”
