Lens combination method for adjusting intraocular optical focal positions

Abstract

The invention discloses a lens combination method for adjusting intraocular optical focal positions. The method includes the steps of firstly, applying a group of convex lens of different degrees in front of eye balls of a myopia patient to allow intraocular optical focal positions to move from original positions to intraocular crystalline lens for 30 minutes; secondly, applying two groups of convex lens of different degrees in front of the eye balls of the myopia patient to allow intraocular optical focal positions to further move from original positions to intraocular crystalline lens for 30 minutes; and thirdly, sequentially and respectively applying two groups of concave lens with multiplied relations and two groups of convex lens with multiplied relations in front of the eye balls of the myopia patient to allow intraocular optical focal positions to reciprocatingly move towards the retina direction and towards the crystalline lens respectively for 30 minutes.

Description

Technical field: [0001] The invention relates to vision correction and physical therapy, in particular to a lens combination method for adjusting the optical focus position in the eye. Background technique: [0002] As we all know, most of the existing vision correction and physical therapy methods adopt or learn from the foggy method. [0003] The so-called fog vision method is to make the tested eye in "artificial myopia state", even if the object image is gathered in front of the retina. Fog vision can reduce the burden of looking close by using a convex lens to prevent myopia. [0004] At present, this method is mainly aimed at myopia patients under the age of 18. Wearing +100DS, +200DS, +300DS convex lenses to work and study for a certain period of time, has a certain effect on a small part of the audience, and improves the naked vision. [0005] It can be seen that the fog vision method has the following defects in the actual application process: [0006] 1. The degree of using ...

AI Technical Summary

Problems solved by technology

[0006] 1. The degree of use of convex lenses is limited, the audience is not universal, the effect is not good, and it is impossible to make personalized adjustment plans that vary from person to person

[0007] 2. Only limited to the use of convex lenses, the optical focus in the eye can only be adjusted in a limited degree in one direction, and the combination of convex and concave lenses is not used

[0008] 3. The constant use of convex lenses results in a limited range of visual acuity improvement, and the audience is very prone to tolerance, and it is impossible to achieve long-term systematic training to help visual acuity recovery
