Device for treating astigmatism and strabismus

Abstract

The invention discloses a device for treating astigmatism and strabismus. The device for treating astigmatism and strabismus has three contributions. A first contribution is that in aspect of astigmatism and strabismus treatment, people surprise to discover that the incurable astigmatism is not caused by eyeballs but lack of actual causes of astigmatism formation in the modern medicine. A second contribution is that people find out the actual causes of the astigmatism: 1, extraocular muscles cannot achieve gathering enough, and intraocular muscles cannot perform enough adjustment; 2, peripheral visual fields of eye grounds are locally lengthened; 3, deformation happens to the edge when eyes look at big-view objects; 4, the extraocular muscles perform local traction on corneas; and 5, double images occur when the eyes look at small-view objects in the distance. A third contribution is that people find out a method for recovering the peripheral visual fields of the eye grounds. By matching the method and comprehensive eye yoga movement disclosed by the patent of CN200980107835.4, the balance of the extraocular muscles is recovered, and internal and external causes of the astigmatism and the strabismus are eliminated, so that the astigmatism and strabismus which are incurable originally can be prevented and cured.

Description

[0001] Technical Field: The present invention relates to a device for treating astigmatism and strabismus Background technique: [0002] Understanding of Refractive Errors in Modern Ophthalmology: [0003] In the resting state of ciliary muscle adjustment, parallel light rays (light rays emitted by objects at infinity) pass through the refractive system of the eye (cornea, aqueous humor, lens, vitreous body), and those focused on the retina are emmetropic eyes, which focus on the front of the retina It is myopia, focusing on the back of the retina is hyperopia, and astigmatism cannot focus into one focus, but forms two focal lines one in front and one behind. [0004] Hyperopia and nearsightedness is the formation of an enlarged blurred spot on the retina, thus blurred vision, while astigmatism is the formation of a diffuse halo on the retina. Myopia, hyperopia, and astigmatism are collectively referred to as refractive errors. [0005] Myopia and hyperopia are mainly caused...

Problems solved by technology

[0006] Hyperopia always forms a blurred image on the retina. Low hypermetropia can move the focus to the retina through adjustment to make the vision clear; while medium and high hyperopia often cannot move the focus to the retina even through adjustment. Therefore, blurred images are always formed on the retina, which cannot be corrected in time during the fast developmental phase. The blurred image stimulation affects the normal development of the optic nerve, which can easily lead to dysplasia of the optic nerve and amblyopia.

Although myopia or myopic astigmatism affects distance vision, near vision is often less affected, so near vision is often normal or close to normal, so visual function is easy to exercise, and amblyopia does not appear; If the minimum diffusion ring is moved to the retina, only eye muscle strength imbalance (and phoria or strabismus) and visual fatigue often appear; ), the minimum diffusion ring cannot be moved to the retina even with adjustment, and the vision is often blurred, manifested as the reduction of both distance vision and near vision, resulting in costly amblyopia on all meridians, and after amblyopia, there is a tendency to develop strabismus
