An optical strabismus corrector

Abstract

The invention discloses an optical strabismus correcting instrument. A pair of rotatable connecting frames is arranged on one side of a strabismus correcting instrument shell; a connecting shaft connects two strabismus correcting instrument shells; an eye lens seat is arranged at the back end of one side of the strabismus correcting instrument shell; an eye lens is arranged inside the end part of the eye lens seat; an object lens seat is arranged at the front end of the other side of the strabismus correcting instrument shell; an object lens is arranged inside the end part of the object lens seat; a pair of rotating lenses is arranged inside the strabismus correcting instrument shell; the rotating lenses are arranged inside the rotating lens seat; a fixing end is arranged at the upper end of the rotating lens seat; an angle rotating button is arranged at the fixing end of the rotating lens seat. The optical strabismus correcting instrument adopts a 3D glasses imaging principle, and a user rotates the angle rotating button to achieve different imaging conditions, so that a strabismus patient has the opportunity of experiencing stereo vision; through training for a certain period of time, azimuth, distance, distance perception are gradually formed and gradually consolidated in living practice so as to establish stereo perception of the strabismus patient.

Description

technical field [0001] The invention relates to the field of optical mechanics, in particular to an optical strabismus corrector. Background technique [0002] According to investigations, 3-4% of people have strabismus, and strabismus patients do not have stereoscopic vision in both eyes, and have great difficulties in life and work such as driving, playing ball, watching 3D movies, and fine manipulation. How to relieve their pain is an urgent problem in ophthalmology. [0003] But at present, traditional ophthalmology at home and abroad have an understanding of strabismus, and believe that the surgical treatment of adult strabismus is only for the effect of cosmetics, but cannot improve vision, and there is no binocular single vision training after the operation. This theory has led to serious misunderstandings in adult strabismus surgery, hesitation before surgery, ghosting, recurrence and even repeated operations after surgery without completely curing the adverse conse...

Problems solved by technology

[0003] But at present, traditional ophthalmology at home and abroad have an understanding of strabismus, and believe that the surgical treatment of adult strabismus is only for the effect of beauty, but not for improving vision, and there is no binocular single vision training after surgery.

This theory has led to serious misunderstandings in adult strabismus surgery, hesitation before surgery, ghosting, recurrence and even repeated operations after surgery without completely curing the adverse consequences of strabismus

[0004] Why do patients with strabismus have poor stereopsis? The main reason is that the eyes of patients with strabismus cannot look at the same target at the same time, and two different pictures are overlapped together, which cannot form "binocular single vision". One eye is designated as the "dominant eye" and the signal from the other eye is suppressed; therefore, patients with strabismus actually use monocular vision, losing the important stereoscopic vision experience of binocular monovision, and the stereoscopic effect is bound to be greatly weakened; Traditional ophthalmology believes that binocular monovision stereo vision is formed within a few months after birth. It is difficult to regain this function after missing this stage. Even if the strabismus is corrected by surgery, it is only a cosmetic effect
