Problems solved by technology

However, the method mentioned by Rafael Navarro and others is to correct the aberrations of the human eye by using hard phase photographs, and the aberration correction components of the human eye made of hard materials cannot be placed inside the human eye to achieve invisible functions and dynamic compensation.

Embodiment 1

[0020] Embodiment 1 is the caliber made by the method of the present invention The continuous relief human eye micro-optic correction device, its production process is as follows:

[0021] (1) Firstly, the Shack-Hartmann wavefront sensing system is used to accurately measure the human eye aberration of a certain patient, and the obtained figure 1 Higher-order aberration maps (i.e., human eye aberration data) shown.

[0022] (2) Design a high-order aberration correction function based on the aberration data of the human eye; the aberration of the human eye will change with time, environmental changes, and changes in the viewing direction. Therefore, the design of the human eye aberration correction element cannot simply take the conjugate of the aberration data like the optical system aberration correction. In the experiment, first set different image factors for various factors that affect human vision, then use computer to simulate the human visual effect, and finally bala...

Abstract

A method for correcting the higher aberration of human eyes, characterized in that it comprises the following steps: a) measuring accurately aberrations with different ranks by adopting measuring apparatus of aberration of human eyes to get the data of aberration; b) designing aberration correcting function according to the data of aberration; c) designing photoetched mask according to the function designed, then preparing mask plate according to the design; d) exposing resists by using mask plate prepared to get micro-rilievo structure made of resists after developing; e)taking microstructure as master blank, transferring the microstructure to material surface of contact lenses by adopting technique of copying. The invention is suitable for the condition of a plurality of complication existing simultaneously.

Description

Technical field [0001] The invention relates to a new method for correcting high-order aberrations of human eyes by using micro-optical elements. Background technique [0002] Myopia is a problem that many people in today's society will encounter. Due to work and study, myopia was caused at a very young age, and as the age grows, the eyes will encounter more problems and produce more complex changes, such as the most common presbyopia, Astigmatism etc. These problems are manifested optically mainly due to the complex deformation of certain tissues of the eye, resulting in serious aberrations. [0003] In order to get back the original bright visual effect, people have long thought of various ways to correct the aberration of the human eye. The low-order aberrations of the eye can be corrected by wearing hard or soft glasses, or by surgical treatment. But so far, the high-order aberrations of the eyes are still unable to be well corrected, especially when multiple problem...
