Method for preparing non-contact glasses for correcting aberrations of human eyes through wave optics

Abstract

The invention discloses a method for preparing non-contact glasses for correcting aberration of human eyes through wave optics. The method comprises the following specific steps that the aberrations of all orders are measured, wavefront correction is carried out, imaging is carried out, wavefront measurement is carried out, adaptive optical control is carried out, parameters corresponding to lenses are designed, and the non-contact glasses are prepared. In this way, according to the method for preparing the non-contact glasses for correcting the aberration of the human eyes through wave optics, the parameters corresponding to the lenses are designed according to corneal topography, the degrees are coaxially, evenly and gradually decreased from the optical centers of lens surfaces to the outer edges, a pixel-level clear zooming function is achieved, the standard of light path whole vision field adaptive human eye physiological light paths is met, meanwhile, based on the wave optics theory, light penetrating through the lenses is adjusted to the optimal angle according to corresponding parameters of the corneas to enter the pupils, images rarely distort, the images can be formed on the retinas accurately and truly, the glasses are suitable for being used by various groups, and the method is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the field of correcting human eye aberrations, in particular to a preparation method of non-contact glasses for correcting human eye aberrations by using wave optics. Background technique [0002] The more traditional vision detection methods can only correct low-order aberrations. It is far from being able to judge the quality of vision simply by checking the correction results with the eye chart, because the eye chart only provides rough information on the accuracy of eyeball refraction, and more details are ignored. For the same two people with a corrected vision of 1.0, there may be a huge difference in their real visual quality. Although they can both distinguish the opening direction of the letter "E", the letter "E" may be clear to them. One is well defined, the other is fuzzy, and the border is fogged. [0003] Vision deviation, in addition to the well-known first-order aberrations such as myopia, hyperopia, and presb...
