The application relates to a myopia prevention and control optical lens based on zoning modulation and edge fusion, and belongs to the technical field of optical lenses. An optical function zone is sequentially provided with a central optical zone, an annular defocus zone and a point-shaped nano lithography point zone from the center of the lens outward, the central optical zone accurately corresponds to the macular fovea region of the retina, the annular defocus zone is arranged with concentric annular defocus microstructure units, and the point-shaped nano lithography point zone is arranged at the periphery of the annular defocus zone and the gap between the annular zones, and serves as an optical buffer zone to soften the optical transition edge.

The application relates to the technical field of chip integrated optoelectronic devices, in particular to a chip integrated optical buffer and a working method thereof. The chip integrated optical buffer comprises an optical waveguide device for inputting and outputting optical signals; a micro-ring resonant cavity capable of resonating at a specified resonant frequency; and an optical loop, which is located in two different directions of the micro-ring resonant cavity and is coupled with the micro-ring resonant cavity. The chip integrated optical buffer and the working method thereof provided by the application realize the optical switch function through the regulation of the resonant frequency of the micro-ring resonant cavity, realize power exchange between the micro-ring resonant cavity and the optical loop by using the mode coupling principle, the two do not contact, the micro-ring resonant cavity does not need to be directly connected into the optical loop, the influence of the optical switch on the optical loop loss is greatly reduced, and the storage time of the chip integrated optical buffer is improved.
