Description

Myopia prevention and control instrument for adjusting function training

Technical Field

The utility model relates to an electronic equipment field for the medical treatment, concretely relates to regulatory function trains myopia prevention and control appearance.

Background

The cause of myopia is still considered to be genetic and environmental factors. The heredity is uncontrollable, and the environmental factors can be partially controlled, so that the influence of the environmental factors on the myopia is more concerned in myopia prevention. When myopia occurs, we are more concerned about how to control the rate of myopia progression. Through many years of clinical observation and scientific experiments, the ophthalmology and visual optics field generally think that the regulation mechanism and the side-center hypermetropic defocus mechanism control the development of myopia. Therefore, the clinical application of the myopia prevention and treatment method is realized by aiming at the two theories.

Improving the internal environment of the eyes and preventing the myopia of children is the field of research and hot focus of the ophthalmology academia at present. Researches show that in the same learning environment with poor vision environment, including the condition of poor eye use habit, some children are easy to be myopic, some children are not easy to be myopic, and the condition is that the environments in eyes are different, and children with good environments in eyes are not easy to be myopic.

There are two functions in the intraocular environment that contribute to the onset of myopia in our eyes, one is accommodative lag, which is a significant cause of myopia onset, and the other is insufficient accommodative sensitivity of the eye. The accommodation ability of the eyes of a person decreases with age, which is why people wear presbyopic glasses by more than 50 years of age. However, this decrease in accommodation with age is a physiological phenomenon in humans and does not lead to myopia, which is caused by a lag in accommodation in children and teenagers.

Accommodation refers to the process of increasing the refractive power of the dioptric system of the eye by actively contracting ciliary muscles, relaxing zonules and enabling the lens to become convex in order to see the approaching object.

The adjusting function is an active energy consumption process, when the sight line changes from far to near, the blurred image of the retina can stimulate eyes to actively generate adjustment so as to enable the image to be clear, and due to the existence of multiple factors of depth of field and tolerance of human eyes to the blurred image, the adjusting response is not exactly matched with the adjusting stimulus, often deviates from the adjusting stimulus, and mostly becomes a lagging state. Such as: the accommodation stimulus for a 33cm object to a human eye is 1/0.33 ═ 3D, that is, the human eye needs to take 3D accommodation to see the object at 33cm, the accommodation stimulus is only related to the distance of the object from the eye. But do not everyone see objects 33cm away with 3D accommodation? The answer is negative. Due to the depth of field and the different tolerance of each person to the blurred image of the retina, not every person can just pay 3D adjustment, and most people have a lag adjustment state, that is, the adjustment actually paid is smaller than the adjustment stimulus, for example, the person can see a 33cm object only by paying 2.5D adjustment, and the amount of lag adjustment of the person is 0.5D. A small percentage of persons are very functional and respond more strongly than they are to adjust, e.g. the person is making a 3.25D adjustment, and the amount of the person's pre-adjustment is 0.25D. Accommodative lag, while less accommodation is given, is optically a hyperopic defocus state, often times when patients experience scleral elongation, i.e., myopia progression.

The reason for insufficient sensitivity of the adjustment is also that the whole process of the adjustment response is always lagged behind the adjustment stimulus, which also leads to the gradual lengthening of the axis of the eye.

Among the regulatory mechanisms, lag and inadequate sensitivity of regulation are believed to be important causes of myopia progression. The household myopia prevention and treatment equipment for intervening the adjustment mechanism is rarely seen, so that the adjustment function training equipment for correcting adjustment lag and improving the insufficient adjustment sensitivity is very important for preventing and controlling the myopia development of children.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an accommodation function trains myopia prevention and control appearance to supply the user to take exercise ciliary muscle, reinforcing accommodation ability and adjustment sensitivity, and then help user's prevention myopia.

The adjusting function training myopia prevention and control instrument comprises an eyepiece part, a lens cone, a partition plate and a plurality of light sources arranged in the lens cone;

the lens cone is a closed cylinder body;

the eyepiece part is arranged at one end of the lens cone and is used for binocular observation of a user in the lens cone;

the partition board is arranged in the lens cone at a position between the two eyes of the user along the axial direction of the lens cone and is used for dividing the visual fields of the left eye and the right eye of the user;

the light sources are arranged in the lens cone and are arranged in at least two rows at the left side and the right side of the partition plate along the direction far away from the eyepiece part;

the device also comprises a control device for controlling the on and off of each light source.

The working principle of the scheme is that a user observes the inside of the lens cone through the ocular part, a light source is lightened at the moment, the user can see the light source clearly and adjust the eyeball unconsciously to change the curvature of the crystalline lens so as to enable the light source to form a clear image on the retina, the light source with different distances is lightened by the control device every time, when the light source is from far to near, the light reaching the eyes is more divergent, the crystal is required to become convex for seeing clearly, the object can be clearly imaged on the retina through more convergence, the distance of the object is changed by utilizing the principle, the convergence of the light can be changed to induce and adjust the training process, the closed cylinder body isolates the external light, the respective visual fields of the left eye and the right eye of the user are divided, the light sources are arranged on the two sides of the partition plate, the targeted training of the single eye is enabled to be possible, and only the light source on one side is lightened, the clapboard divides the visual fields of the left eye and the right eye, so that only one side sees the distance change of the light source by a single eye; if the light sources on the two sides are on or off, both eyes can receive training.

The object moves close, the adjustment is increased, the object moves far, the adjustment is relaxed, and the adjustment sensitivity can be trained through the dynamic change of the distance of the object. The ciliary muscle of the user continuously acts to change the curvature of the crystalline lens, so that the ciliary muscle is exercised, and the ciliary muscle which is continuously exercised enhances the adjusting capability, thereby being beneficial to preventing myopia of the user; in addition, during binocular training, due to the fact that the visual lines of the left eye and the right eye are blocked by the partition plates, image separation is caused to the human eyes, the human brain needs more fusion functions of the visual center, workload of the fusion function of the visual center of the human brain is increased, the visual fusion function and sensitivity of the central center are further exercised, adjustment lag is improved from the aspect of eye exercise and the aspect of brain perception function, and adjustment sensitivity is trained.

Further, the eyepiece portion includes a plurality of switchable positive/negative spherical lens groups.

The light source may be made to have a number of different images that are either further or closer to the actual distance of the light source from the eye. Although the distance of the object can train the adjusting function, the object can not be infinitely far away from the eyes and can not be infinitely close to the eyes, and the training range is limited. For this purpose, the adjustment training can be induced by adding positive and negative sphere lenses in front of the eyes to improve the light vergence.

If the positive sphere lens is placed in front of the eye, the light rays can be converged once before reaching the eye, so that the adjustment of the lens is weakened, and if the negative sphere lens is placed in front of the eye, the light rays can be diverged once before reaching the eye, so that the adjustment of the eye can be induced, the adjustment effect of the lens is enhanced, and the diverged light rays can be converged on the retina. The purposes of improving the regulation lag and training the regulation sensitivity are achieved by placing positive and negative spherical lenses with different degrees in front of eyes. For example, in order to see an object at 33cm, the human eye needs to pay 3D adjustment, if a +3D sphere is placed in front of the eye, the adjustment needed by the eye is 0, which is a completely relaxed state, and if a-3D sphere is placed in front of the eye, the human eye needs to pay 6D adjustment, which can widen the adjustment range in the adjustment function training.

Further, the lens group further comprises a plurality of switchable base-out triple prisms.

The normal crowd adjustment and the set usually occur in a linkage mode, the adjustment is called as the adjustment on the adjustment set ratio, namely the AC/A ratio, the range of the value is 2/1-6/1, the average value is 4/1, namely the adjustment set of 4 units induces 1D adjustment, and therefore the training of the eye adjusting force can be strengthened by using the triangular prism. The prism attachment can change the adjustment set, namely the AC value, to change the adjustment requirement, namely the A value to stimulate the adjustment response of human eyes, thereby achieving the purposes of improving the phenomenon of adjustment lag and insufficient adjustment sensitivity.

Further, the lens group is mounted on a switching mechanism driven by a controllable driving mechanism, and the control device is also used for controlling the switching of the lens group.

The lenses can be conveniently switched according to the requirement of training design.

Further, the device also comprises an endoscope part and a spraying part;

the lens part comprises a cavity with an opening on one surface, and the bottom surface in the cavity, which is opposite to the opening, and the end surface of the lens barrel, which is provided with the eyepiece part, share one surface;

the mist outlet end of the mist spraying part is positioned in the cavity of the room mirror part and is used for spraying atomized liquid into the cavity of the room mirror part.

After the training of a stage is completed, the eyes of the user cling to the opening of the glasses part, the spraying part sprays into the chamber, and the atomized liquid can more easily act on ciliary muscles in human eyes to help the user relax the ciliary muscles.

Further, the light source comprises a white light sighting mark lamp capable of emitting white light, and a sighting mark image is further formed on the white light sighting mark lamp.

The white light makes the visual target image more striking, and the visual target pattern can guide the user to watch, induces the regulation demand of human eyes.

Further, the light source comprises color light sighting target lamps, and each color light sighting target lamp comprises a plurality of light-emitting elements which respectively emit different color light.

The light has different wavelengths, and the dioptric system of the human eye has a certain refractive index. The adjustment is trained by using different refractive powers of different wavelengths of light on the same medium.

Further, the color light sighting target lamp comprises a red LED lamp bead, a green LED lamp bead and a blue LED lamp bead.

The red light has long wavelength, the refractive index of the medium is low, and the refractive power is small, so that the image is formed behind the retina after the image is formed by the eyeball optical system. The green light wave length is short, the refractive index to the same medium is large, the refractive power is strong, the eyeball optical system images in front of the retina, training is carried out through the change of the light wavelength, more subtle adjusting change is brought to the eyeball, and the training effect is better.
