Based on the higher-order aberrations and myopia defocus hypothesis, and adopting the technique of coexisting dual stimulus signals, forward defocusing is added to the lens, and higher-order aberrations are introduced through quantization modulation using a free ring surface. The two microstructures are interlocked and connected to form an annular shape, in order to generate sufficient myopic defocusing and higher-order aberration modulation signals within the range of pupil scanning. The coexistence of dual mechanisms not only solves the early adaptability problem of simple higher-order aberrations, but also avoids the decrease in energy efficiency in controlling the post defocusing stage of simple myopia, achieving a more effective suppression of axial growth.
