Title:
LENS COMPLYING WITH RETINA RESOLUTION RATIO, AND FITTING PRESCRIPTION AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/178862
Kind Code:
A1
Abstract:
A fitting prescription for a lens complying with the retina resolution ratio, comprising first measuring optical characteristics of a patient (2) and transmitting the optical characteristics to a computer, conducting design by using an optical aided design module, conducting evaluation by using an optical analysis module, introducing database retrieval, conducting simulation by an optical simulation system, and finally performing conversion to obtain a design format conforming to mechanical production and manufacturing a lens by using a 3D printer or a cutting system of a numerically-controlled machine tool. Also disclosed is a lens complying with the retina resolution ratio, and a manufacturing method therefor. According to the fitting prescription, design for a lens complying with the retina resolution ratio can be obtained by controlling precision in measurement and correction; by establishing a database for personalized customization, design parameters for the glasses are optimized according to age and career factors of different patients, so that fitting and manufacturing for a lens can be seamlessly integrated, information is communicated therebetween, the tolerance is smaller, the glasses can significantly improve the eyesight, and the discomfort on the eyes caused by wearing the glasses is reduced.
