Description

Myopia prevention and treatment device {Device for preventing and treating myopia}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention generally relates to a device for correcting visual acuity, and more particularly, to a device for correcting myopia by close de-focusing objects training.

Currently, one third of the world's population suffers from myopia and the situation is getting worse. There is no ideal or effective device for correcting myopia. In the past, Shenzhen Zhen Weikang Technology Company produced "Phoenix Eye 2000" using red, blue and green visual frequency light to activate the retina and improve vision, but the effect is not satisfactory. Not slow CN2081103U discloses a lens that is typically worn to correct myopia, where the upper side of the lens is for correcting hyperopia while the lower side is for correcting myopia. However, it is difficult to focus on objects, making it difficult to make inversion changes to correct myopia or control myopia progression, and multifocals are bad for young eyes. In 1922, Sheard invented "far fogging" by wearing convex lenses in front of the eyes, which had some effect on correcting myopia, but could not be used widely because they did not result in satisfactory and stable results. From 1980 to 1985, some elementary students experimented with wearing 1.5D convex lenses when reading and writing to correct myopia, a "near fogging" method. Indeed, this method may slow the progression of myopia slightly but cannot effectively correct myopia. Some other therapies using convex lenses have the same problem and cannot be distributed for use.

It is an object of the present invention to provide a method and apparatus for correcting certain myopia with proximity defocus training. The present invention will be used to correct near myopia especially with the characteristics of significant effect, rapid correction, no side effects, simple structure, ease of expansion, simple and simple method. The present invention is particularly suitable for the prevention and treatment of myopia and the rapid treatment of functional myopia in children and young people.

The technical solution of the present invention is a near-field defocusing myopia correction device comprising a spectacle frame, a lens frame and a lens. The feature is that the diopter of the lens is Φ = 1 / u + A + B-ΔΦ, where A is a rectified diopter of the primitive and B is a defocusing diopter with a selection from 0.1 to 3D. diopter), ΔΦ is the correction value, u is the distance between the observation object and the lens during training. When the eye is close to the lens, ΔΦ should be about zero, the same as when wearing glasses, and the decrease ΔΦ can be calculated by experiment, and when the eye's training position is far from the lens, In order to achieve the corresponding effect, the lens diopter value Φ should also be reduced accordingly. This also depends on the relevant optics such as ΔΦ = [(1 / u + A + B) ² u + 2 (1 / u + A + B) + 1 / u] / (2 + uA + uB + u / s) It can be calculated, where s is the distance between the lens and the eye. This lens may be defined as a binocular dual lens, a monocular single lens, or a monocular single lens.

The distance u between the subject under training and the lens should be about 130 mm-about 1000 mm.

In order to improve the applicability and convenience of reading and writing training, the distance u between the subject and the lens under training should preferentially be between about 200 mm and about 500 mm.

In order to increase the applicability and generality and to improve the myopia prevention effect, the distance u between the subject and the lens under training should first be a value of about 250 mm to 330 mm.

The distance u between the object under training and the lens is given a distance control mechanism such as a sound, light, electric, mechanical or manual instrument. The instrument must be able to control the distance between the subject and the lens within the range of the u value during training to keep the eye in a condition that can simultaneously train and rest the eye. To train eye relaxation, blur and vision distance adjustments are made by controlling or adjusting the distance.

The mechanical distance control mechanism is a fixed or adjustable desk frame. The structure should be simple, stable and convenient. The lens frame may be a better desk frame, meaning either a fixed or adjustable desk frame distance control structure, or decorative eyeglass frames and glasses (such as glasses with stands or headgear), which include distance control. There should be a ruler or other flexible measuring controller.

If an observation object such as a visual indicator can be placed, it is preferable to fix the loading plate (or platform) under a fixed or adjustable desk frame. The loading platform should be constructed with a lift structure so that the trainer can adjust the position to train easily.

The lens can be a single lens or a composite lens of equivalent diopter. For the sake of better effect the lens should be a composite lens including an eyepiece and an objective lens. The eyepiece is a Φ2 convex lens, the objective lens is a Φ1 concave lens, and the distance between the eyepiece and the objective lens is fixed or adjustable, the distance of which is expressed as Distance between the eyepiece and the objective lens), where u should be the distance between the eyepiece and the object observed during training, and a light breaker added between the eyepiece and the objective lens. The lens can also be a series of interchangeable lenses or a focusing lens.

The subject in question can also be a book. In order to enhance the training effect of the eye at the appropriate spatial frequency, a special visual display is preferred for the above-described observation object.

The above-mentioned special visual display consists of different or equally sized characters (ie, items) such as line drawings, ordinary letters, numbers, or graphic micro-vision charts or visual display booklets. Can be.

The special visual display may be an LCD screen of the Playstation in consideration of an increase in interest and interest of patients, an improvement in visual psychological effects, a guarantee of training time, or a combination of learning and reading training.

The above-mentioned special visual indicator may be a single visual indicator for a double eye or a single eye, but the dual visual indicator is more preferred. Dual visual indicators are parallel to coincide with binocular binoculars, which is easy for binocular joint training and convenient for binocular parallel sight, thus reducing eye coordination and convergence, reducing eye coordination, coordination and hyperopia Will help you change. The distance from center to center between the two visual indicators is about 20 mm to about 100 mm, and the two visual indicators may be the same or different, which is judged by the principle of convenient matching.

In order to improve the corrective effect of single vision match training, or for better formation of dual visual indicators, it should be possible to minimize eye focus and convergence coordination to aid eye relaxation, coordination and changes in hyperopia. The two lenses described above should have a compound prism on the side of the nose or below the inside of the nose, and the prism degree of P = 3 ^Δ -15 ^Δ may be good, and P = 50 × d ₁ / u. Where d ₁ is the distance between the primitive eye, u is the distance between the visual display unit and the front lens, or two lenses may be two eccentric lenses.

A blocker can be placed around the lens in the device to concentrate and produce a better effect to prevent human eyes from being perceived near each other and controlling perspective. In the case of a dual visual display, a mechanism may be added to avoid the clocks crossing to prevent clock crosses caused by crossed diplopia of the eye's clock.

In particular, the method employing a near-field focus myopia correction device is:

Check A for trainer primitives.

The value of the distance u between the lens and the observed subject during training is selected with reference to habits and the need for near work and study.

Choose the values of B and ΔΦ.

From the above-described values of A, u, B and ΔΦ, the value of diopter Φ can be calculated through the equation Φ = 1 / u + A + B-ΔΦ required for the selection of the training device.

The observation object is placed in front of the lens, the distance between the observation object and the lens is set as u, and the distance u between the object and the lens is adjusted by sound, light, electric, mechanical or manual method during training.

The trainer observes the observation object through the lens and repeats the training until a clear image of the observation object is obtained.

The process is repeated while gradually increasing the diopter Φ of the lens. Through this training, the vision of the trainer can be expected to reach the desired state in stages. If there is no change in the diopter Φ of the lens, the defocus training can be continued by referring to the above equation and the updated A through the adjustment of u.

Thus, the method is designed based on the diopter of the lens, Φ = 1 / u + A + B-ΔΦ, where ΔΦ is a correction value. When the eye is close to the lens, it corresponds to decorative glasses, and when the eye is away from the lens during training, the diopter Φ of the lens should be reduced accordingly to produce the same effect as defocusing the object (reducing the ΔΦ obtained in the experiment). ), And also the related optical, ΔΦ = [(1 / u + A + B) ² u + 2 (1 / u + A + B) + 1 / u] / (2 + uA + uB + u / s) Where s is the distance between the lens and the eye. This training distance must first be determined in terms of the distance u between the observation object and the lens, i.e. the distance u between the observation object and the training lens, with respect to the need for work and study at close range. u ranges from about 300-1000 mm, about 200-500 mm, or about 250-330 mm. The value of B, which is determined according to the judgment difficulty of the observer, is still required. If it is difficult to identify, the lower limit is selected, and the upper limit is relatively easy. Φ is determined by the equation Φ = 1 / u + A + B = ΔΦ. In accordance with this regulation, defocused training treatment should be performed when working and studying at close range. When vision is restored, defocus training can be continued by adjusting the distance u between the training subject and the lens in accordance with the above formula and recovered A to further improve vision. Or change the φ by the equation Φ = 1 / u + A + B-ΔΦ and keep u constant so that defocused training can be continued by the recovered A and equation. Distance control mechanisms such as sound, light, electrical, mechanical or manual instruments may be used to adjust the distance u between the subject and the lens under training.

The design and treatment apparatus of the present invention is as follows. The present invention is particularly designed for near-field training, reading and writing to maintain the eye frequently in a defocused state, i.e., in the state of focusing on the vitreous rather than the retina. Discontinuously adjusts the blurring and primitive power of the camera. This long period of training can serve the purpose of preventing and treating myopia.

Static diopters of a normal eye can produce a focal focal point parallel to the retina without active refraction. For functional recovery, long-range near-diopter perspective adjustments should be avoided, and parallel vision is preferred. In myopia patients, while the ciliary muscle of the eye is in a convulsive state, experiments show that only myopia perspective control cannot be reduced, creating primitive "blur" through the lens and diopter of the eye within the glass in front of the retina. When the eye is in a defocused state of the primitive subject to form a system, it is very clear that the ciliary muscle can relax to its normal state as a result and the spasm can be released quickly and effectively. Thus, there is no need for only low power convex lenses applied at close range to reduce eye perspective control. Even in the case of applying the medium and low degree convex lenses, myopia observation is freely performed without considering the distance of the object to be observed and cannot guarantee an ideal or reliable effect, and a specific distance for use can be considered first. Effective defocused subjects can be obtained by matching a particular lens with an appropriate lens. Defocus B of defocus should be within about 0.1-3D or about 0.25-3D. If it is small, for example, about 0.1-1D, it is easy to identify, feels clean, and is suitable for long time training and learning, and if it is less than about 0.1D, some defocus is not possible because reversed adjustment therapy cannot work. Does not happen. For example, if it is too big, about 2-3D, it will be quite cloudy, too much training load, and eye fatigue will be easy.Training time should not be too long. It is not possible to apply learning and training, and moreover, empty myopia may occur, which should also be avoided, and around 1D is adequate in general. This is the prevention and treatment mechanism of defocus. To strictly limit the range of use, manual control alone is not sufficient. The distance control mechanism is designed to satisfy this requirement. Initially, people felt that the visual display was not clear enough, but after looking and focusing for a long time, the subject became increasingly clear and clear. This is a method of primitive perspective control. This method allows the eye to actively or diopter the diopter to zero, stops eye growth in the axial direction, and improves primitive perspective control through defocused images on the retina, leading to hyperopia. Prevention and treatment of structural myopia can be realized. Shoeffel and Schmid used convex and concave lenses to conduct out-of-focus experiments on animal eyes in 1988 and 1996, respectively. Successful treatment of primitive and myopia in animals has provided evidence of biostructure testing that defocus can alter the diopter and visual acuity of the animal.

The visual indicator effect is to focus the patient on reading therapy. It uses symbols of varying difficulty to identify at different visual-spatial frequencies and exercises, facilitating the interest and enthusiasm of the patient during training, leading the patient to the symbols that are intentionally difficult to identify, so that effective eye control of the eye It may arise and raise the desire for treatment of the patient, taking into account the principles of psychology and visual ecology.

The main factors in myopia are (1) genetic and evolutionary factors, and (2) environmental factors. Genetic factors cannot change as internal factors from humans, which determine the likelihood of occurrence and progression of myopia, while also being influenced and promoted by environmental factors. Environmental factors are external factors, and eyes are light sensors that change and progress according to the external light conditions. When light is emitted from the near environment, near vision adjustment is achieved, and parallel light of far vision and far vision on the side of the vitreous in front of the retina promotes reverse change. Long-term roots and lesser ones create internal factors that cause myopia to progress and genetic changes as vision compensation. Thus, environment and light are key to disease and the key to the prevention and treatment of myopia. Thus, changes in the environment (or mimic the source to change the angle of light emission in the eye) from the root to the root are essential, which can develop primitive possibilities and stop myopia.

When looking at a distant point of healthy eyes, the adjustment of the eye is relaxed and the concentration of the eye becomes zero, and the object to be observed is formed in the fovea of the eye, and when looking at a close point, the eye's concentration and Coordination thus interacts to maintain the formation of monocular and central vision. Changes in the environment of use of the eye, inadequate use of the eye, and indefinite use of the biological are opportunities, especially when young, leading to deterioration of the hyperopia, thus making the human optic nervous system more suitable for canine emission. Myopia grows rapidly and progresses.

Numerous animal experiments, anatomical investigations, and large amounts of statistical data on myopia principles for chickens, young monkeys, and cats have laid a solid foundation, ie, the main cause of myopia comes from long-term tendency. In contrast, prolonged eye concentration and aggressive coordination can be avoided and more reverse coordination compensated for, helping to prevent and treat myopia.

From an ophthalmic neurological theory point of view, the concentration and coordination of the human eye and the pupillary contraction are correlated, and according to the Donders line, when the concentration of emmetropia is zero, the corresponding coordination is zero, In the case of greater concentration, the adjustment is greater. The reason for accommodative myopia is long-term tendency and excessive concentration and coordination. As a result, coordination does not help relaxation of concentration at all, and coordination and concentration are inconsistent. After human coordination changes the concentration to zero, defocus training will promote coordination to zero to satisfy the original response principle. This training can prevent and treat myopia as the adjustment can return to normal and return to the original placement rules. The effect of the dual visual indicator combined with the triangular prism can achieve this goal.

Due to the many implementations, it is known that the outstanding effects and features of the present invention are special for myopia correction training, and are characterized by rapid calibration, safe and reliable, simple structure, no side effects, ease of expansion, and simple and scientific methods. In general, most children's myopia can improve to about 1.5 within about 3 months.
