Adaptive defocus microlens juvenile prevention and control lens

Abstract

The application discloses a kind of self-adapting regulation defocus microlens adolescent prevention and control lens, comprising: lens;The front surface of lens is equipped with center clear zone and micro-lens defocus zone, micro-lens defocus zone has upper side distance viewing area and lower side near viewing area, upper side distance viewing area and lower side near viewing area are in imitation shell shape, and they are asymmetric, upper side distance viewing area is distributed low-density medium defocus amount microlens, and lower side near viewing area is distributed high-density high defocus amount microlens, and the curvature of microlens is gradually steep from center to periphery, and defocus amount is continuously increased.The application sets up the microlens array of upper and lower distance viewing area, and optimizes image in partition, reduces fatigue, and the defocus amount of gradient change is used to realize self-adapting regulation mechanism, and defocus amount is dynamically regulated with scene, and defocus is effective all-weather, and the prevention and control performance of myopia is improved.
