Abstract

This invention discloses a partitioned scattering optical lens for myopia control and its design method, applied in the field of optical technology. It aims to solve the problem in existing technologies where central visual quality and peripheral myopia control effects cannot be simultaneously achieved. The optical lens includes a central optical zone, a peripheral optical zone, and a smooth transition zone. The central optical zone has a low scattering coefficient and a high MTF, achieving a high modulation transfer function and low scattering loss. The peripheral optical zone has a high scattering coefficient and a low MTF, used to induce peripheral myopic defocus. The smooth transition zone achieves a continuous and gradual change in scattering coefficient to avoid abrupt visual changes and ensure visual comfort. The design method includes obtaining eye parameters, defining optical performance targets, designing microstructures, and performing simulation optimization. Through the above scheme, this invention effectively decouples central visual acuity and peripheral myopia control, ensuring high-definition vision, inhibiting myopia progression, and improving wearing comfort.
