Description

Novel eye position compensation prism for myopia prevention and control

Technical field

The utility model relates to the field of vision correction glasses, in particular to an integrated eye position myopia correction mirror suitable for adolescents, capable of preventing and controlling the progression of myopia and correcting strabismus.

Background technique

Humans have succeeded in inducing juvenile animals into myopia and successfully treating the myopia that has occurred, which indicates that the conclusion that "true myopia is irreversible" does not apply to animals. So why hasn't humans been able to overcome their nearsightedness?

Eye position! Still eye position!

What is the root cause of human myopia?

Eye position, looking close, is actually an excessively strong state of binocular concentration.

What is the cure for animal myopia?

Eye position, because animals do not need to read books to learn. The binocular set often approaches zero.

What are the causes of human myopia being incurable?

Eye position! Because on the road of human myopia, there is no theory, theory and practice about eye position.

What is our secret weapon for preventing and controlling myopia?

Eye position, we exclusively launch the "eye position theory", so that myopia prevention and control is no longer a problem.

Eye position theory

To put it simply, the eye position means the position of the eyeball. Unlike traditional eye examinations, we roughly divide the eye position into five types temporarily, severely oblique, slightly oblique, orthotopic, slightly implicit Oblique, severely implicit. Corresponds to A, B, C, D, E in the figure.

It can be seen from the figure that when reading at a close range, the A eye position has the largest amplitude of internal rotation, so the two eyes receive the greatest tension. Even when looking far away, the eyes still need internal rotation, so the eyes are prone to Pain and swelling, prone to myopia, those children who develop myopia at the age of 5, 6 belong to this eye position. The B eye position is not substantially different from A, but the situation will be relieved. The age at which myopia occurs is relatively late, generally at the age of 8 or 9 years.

Type C eye position is far-sighted and relaxed, and the tension produced when looking close is weaker than the above two types, so the situation will be better. Myopia often occurs around 10 years old. Type D eye positions are fundamentally different from the above three types. The difference is that when the eyes are viewed close, the internal rotation is aligned with the target, the amplitude of the internal rotation is small, and the eyes are less stressed. Occurrence of external rotation, which produces reverse tension, can effectively offset part of the tension, so that the occurrence time of myopia can be greatly pushed back, usually after 15 years of age.

Type E eye position is the best eye position. The amplitude of internal rotation is the smallest when viewed near the eyes, and it is difficult for the eyes to experience visual fatigue. At the same time, the amplitude of the external rotation of the eyes is greater when viewed far away. Therefore, it is generally difficult to develop myopia, or even if it occurs, it is easy to stop at low myopia.

The solution of myopia——starting from the eye position

Why is it that myopia is not a complicated problem, but human beings still cannot overcome it?

Because from the fog vision therapy, to various traditional Chinese medical methods, to the gradual multifocal technology, the eye position has not been considered.

Why are some people short-sighted, while others are short-sighted, and still others are not short-sighted no matter how they study?

These difficult problems that cannot be explained by modern optometry can be explained perfectly with the eye position theory, and the expected results have been achieved in practice.

Why do some people no longer develop low myopia, while others have reached 800 degrees but continue to develop?

All are caused by the eye position. Unreasonable eye position makes the occurrence and development of myopia extremely easy.

Why are the myopia degrees of the left and right eyes different, and some people have a large left and right gap?

This is caused by the eye position problem, and it is also the key content of our eye position theory, which is also the key to the new eye position compensation prism lens.

Embodiments of the invention

A new type of eye position compensation prism for myopia prevention and control in this embodiment is shown in Figs. 1-3. It includes a frame 1, an endoscope 2 is installed in a frame 101 of the frame 1, and an outer lens is provided in front of the endoscope 2. 3, a hanging structure 4 is connected to the middle of the outer mirror 3, and is detachably connected to the frame 1 through the hanging structure 4, the inner mirror 2 is a composite lens formed by a concave lens and a triangular prism with a base inward, and the outer mirror 3 is a convex lens and A composite mirror formed by a triangular prism with a base inward, and the outer mirror 3 is provided with a blue light-resistant film layer.

The endoscope 2 is configured according to the eye position parameter, so that the relaxed state of the eye position of the eye always simulates the state of the eyeball rotation with moderate recession.

The refractive power of external mirror 3 is + 1D ~ 3D, with a deviation of ± 0.12D, and the power of its prism is 1 △ ~ 4 △, with a deviation of ± 0.37 △; the power of the prism is based on the corresponding part of the pupil, and its base orientation deviation is less than or equal 0.5 degrees.

A circular groove 103 is provided on the top of the connecting portion 102 between the lens frames 101, a magnet 104 is placed in the circular groove 103, and a hanging structure 4 is installed on the top of the connecting portion 102.

The hanging structure 4 includes a connecting frame 401, a circular table 402, and a hook 403. The circular table 402 is fixed to the bottom of the connecting frame 401. The circular table 402 is sucked in the circular groove 103. The inside of the connecting portion 102.

The mirror surface of the exterior mirror 3 is covered with a coating, and the coating excites light quantum activated retinal cone cells to increase the intensity and area of visual stimulation.

Endoscope 2 telephoto principle: It is composed of a concave lens and a prism, and the concave lens can correct myopia. We can see clearly in the distance. The inward-facing triangular prism on the lens can reduce the adjustment as far as possible, and keep the eye position of the far-away position always open, that is, the far-sighted view can be changed to see farther, so that They are in a constant telephoto state. Therefore, our inner living glasses not only have the sharpness of ordinary glasses, but also have the function of opening the eye position that ordinary glasses do not have, and always maintain the telephoto status. The glasses have fundamentally changed the state of eye adjustment, collection tension and mutual inconsistency when working at close range.

Working principle of external mirror 3 (refer to Figure 4): The role of convex lens is to reduce adjustment. The light that enters the eye when looking at it is divergent, and it is parallel when looking far away. After entering the eye, the parallel light does not need to be adjusted to be imaged on the normal retina, but the divergent light (that is, the light that looks near) is like normal eyes It must be adjusted before imaging onto the retina. Long-term adjustment can stimulate myopia. The convex lens can condense the light and make the divergent light become parallel light into the eye. Therefore, reading does not need to be adjusted.

However, the human eye sees far and near, so that not only adjustment is needed, but also collection, and the adjustment collection is performed simultaneously. Therefore, it is necessary to change the direction of the light entering the eye through the triangular prism inward of the base to disperse the light. The light entering the two eyes is refracted by the prism to become the light perpendicular to the eye. By adding a convex lens with a triangular prism inward, the adjustment and collection of the glasses can be solved at the same time. Reading and writing through this lens is equivalent to telescopic training.

In actual use, the endoscope 2 is used as a living mirror, which is worn in daily use to achieve a long-distance view, and always maintain a telephoto state. Eye adjustment, tightness, and mutual inconsistency when working at close range. When working learning is required, the external mirror 3 and the circular table 402 of the hanging structure 4 are fitted into the circular groove 103 of the connecting portion 102 and the hook 403 is fastened to the inside of the connecting portion 102. Through the cooperation of the external mirror 3, the patient can also perform telescopic training while studying and working.
