Array-patterned micro-structures in spectacle lens for myopia control via image blurry

Using micro-structure components in the spectacle lens has enabled myopia progression control in children and teenagers. However, the optical design of these spectacle lenses has never been discussed, leading to a lack of correct understanding of the underlying optical treatment principle. In this work, the array-patterned hexagonal lenslets with two opposite addition power designs were proposed to construct the lenslet-array-integrated (LARI) spectacle lens developed for an ongoing randomized controlled clinical trial and to support the optical approach to myopia control via image blurry. We found that the phase modulation induced by the micro-structures of the lenslet array contributes to the increase of RMS wavefront aberrations, leading to the image blurry, further inspiring the novel array-patterned microstructure design with high-order phase elements (HOPE). The optical performance of both LARI and HOPE spectacle lenses was investigated by simulation and experiment.
