Description

Amblyopia treatment device capable of intelligently guiding visual stimulation

Technical Field

The invention relates to the field of medical instruments, in particular to an amblyopia treatment device capable of intelligently guiding visual stimulation.

Background

Amblyopia is caused by abnormal visual experiences such as monocular strabismus, ametropia, high ametropia, form deprivation and the like in the visual development period, the optimal correction vision of a single eye or two eyes is lower than that of a child with a normal age, and no organic lesions are caused in eye examination. Lower limit of normal value of vision for children of different ages: the lower limit of the normal vision of children aged 3-5 years is 0.5, and the lower limit of the normal vision of children aged 6 years and above is 0.7. Amblyopia is an eye disease which seriously harms the visual function of children, and if the eye disease is not treated in time, the amblyopia can be aggravated and even be blind.

The ametropia and ametropia weak are the highest in the prevalence rate of amblyopia. Due to different vision of two eyes, different imaging sizes and definitions of retinas of the two eyes and large and fuzzy imaging of yellow spots of one eye with higher diopter, fusion reflex stimulation of the two eyes is insufficient, so that normal development of visual function is hindered, the visual deterioration of one eye or two eyes is caused, and various sensory functions are lost. The vision deterioration is only a primary expression, and the advanced expressions comprise impaired spatial localization, reduced contrast sensitivity, low and constant stereoscopic vision, a spatial crowding phenomenon and the like.

The degree of amblyopia is not only related to the degree of the refractive error, but also to the nature of the fixation. The amblyopia imaging is schematically shown in fig. 1 and fig. 2, fig. 1 shows the imaging effect of a normal eye, the image of an object is located on the macula lutea of the fovea, and the imaging is clear. While amblyopic eye imaging is complex, for example: the imaging may fall in front of the macula, as shown in fig. 2, similar to myopia; also behind the macula, similar to hyperopia; the imaging may also fall on the macula, but is affected by the visual system and does not respond positively in the brain. The first two conditions are affected by the refractive power of the lens, like the macula which does not fall on the fovea, superficially this is similar to the imaging phenomena of myopia, hyperopia, but the pathology is completely different.

The lens of the myopia and hyperopia eyes are deformed, the muscle adjustment can not make the image fall on the macula lutea, and the condition can be adjusted to the image position by wearing the glasses. While the lens of the amblyopic eye may still be in a normal state, which has the ability to image at the macular site, but due to the abnormal visual experience that has developed, the brain is not actively directing the visual stimulus, i.e. the ciliary muscles are not active or lazy to accommodate the lens. This reason results in the inability to treat amblyopia with the method of wearing glasses.

There are 6 current conventional methods for treating amblyopia: covering therapy, fine eyesight training, grating training, pricking training, eye muscle training and red filter therapy. Wherein: covering therapy is an ancient and effective treatment for amblyopia, which allows the amblyopia to undergo exercise by covering the active eyes. It is one of the simplest, most economical and most effective methods for treating amblyopia of children. However, the covering time needs to be scientifically adjusted, the covering for too long time causes the asthenopia, and due to the inherent pathological reasons, the adaptation to the imaging effect (unclear imaging) in the fatigue state is possibly caused, and the active adjustment is not performed any more. This causes the covering therapy to be passive and the physician is unable to take active treatment.

In summary, the following problems exist in the prior art: the covering therapy for treating amblyopia adopts passive therapy, and has low stimulation efficiency and poor treatment effect.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

Principle of method

The aim of the existing covering therapy is that after covering healthy eyes, weak eyes are forced to adjust the diopter of crystalline lens to obtain clear imaging. The brain develops a self-adjusting habit by continuously exercising ciliary muscles and neural sensitivity. The method has a problem that the brain has a desire to keep clear imaging at the early stage of covering and strengthening eyes, and the amblyopia eye is regulated to a certain degree. However, over time, the abnormal visual experience that amblyopic eyes have developed slowly reduces the willingness to adjust the brain. I.e. covering for a period of time, the amblyopic eye stops the therapeutic exercise. In this case, conditions such as reduction of light due to masking of healthy eyes may adversely reduce visual functions of amblyopic eyes, which may be a cause of insignificant or poor effects of masking of parts of cases.

It is clear that the critical period of willingness of the brain to maintain clear imaging is exploitedThe optimum time for the amblyopia eye exercise treatment is set as T_b. The duration is obtained by darkening the dimming film of the eye-care spectacle lens, and the darkening process simulates a covering process, so that the amblyopia eye can voluntarily adjust the lens diopter and the pupil size to obtain clear imaging. The dimming film can stimulate the brain and guide the visual stimulation. At T_bIn the time quantum, become curved membrane work, carry out focus according to setting for the procedure and adjust, the parameter includes: focal length maintenance duration t_lmAnd a focusing time period t_la，T_b＝t_lm+t_laIt is usually designed according to the degree of amblyopia and the purpose of treatment. Focusing time period t_laTypically in the range of 100ms to 1000 ms. t is t_la<At 400ms, the visual stimulation is sudden, namely imaging is suddenly blurred, the intensity of the visual stimulation is high, and discomfort such as dizziness and the like is easily caused due to too frequent visual stimulation. t is t_la>At 1000ms, the visual stimulation is weak and the brain's will of regulation is difficult to trigger.

In addition, the guide frequency n needs to be designed specifically, namely the guide frequency of each visual activity period, and n/d and d are day, which means each day.

As shown in fig. 3, the amblyopia treatment device with intelligent guiding of visual stimuli according to the first embodiment of the present invention includes:

the first dimming film is arranged on a first lens of the glasses, the first lens is a right lens for example, and the first dimming film is used for adjusting the light transmission intensity of the first lens under the condition of electrifying;

the second control module sets up on the glasses with first inflection membrane homonymy and the first inflection membrane of electricity connection, for example, sets up on the peripheral frame of left spectacle lens, and the second control module includes: a second power supply and a second control circuit board.

Here, left and right are opposite, if the first lens is set as a right eye lens, the second lens is a left eye lens, and if the first lens is set as a left eye lens, the second lens is a right eye lens. In this embodiment, a curvature changing film is provided on the lens for amblyopia, and a light adjusting film is provided on the lens for eye health.

By applying voltage or further adjusting voltage, the light adjusting film can uniformly adjust the light intensity of the light transmission and change from transparent to opaque so as to simulate covering treatment. By applying voltage or further adjusting voltage, the bending membrane can uniformly adjust diopter and change imaging focal length. Through proper refraction and timely frequency change, visual stimulation is guided, so that the brain actively adjusts muscles such as ciliary body and the like, and the treatment purpose is achieved.

Further, as shown in fig. 5, the first light adjusting film is provided on the outer side of the first lens (right eye lens) for easy masking and fabrication. The area of the first light adjusting film is equal to the area of the first lens or covers the main body part of the first lens, so that the covering function is realized.

Further, as shown in fig. 4, the first bending membrane is disposed inside the second lens, so as to adjust diopter and manufacture. As shown in fig. 11 and 12, in the case where there are a light adjusting film and a curvature changing film on each lens, the curvature changing film is provided on the inner side of the lens (near the eyeglasses), and the light adjusting film is provided on the outer side of the lens (far from the eyeglasses), so that the light adjusting film and the curvature changing film do not interfere with each other.

Further, as shown in fig. 6, the first light adjusting film includes: two transparent conducting layers and be located and connect gradually between two transparent conducting layers: an ion storage layer, an electrolyte layer, and an electrochromic layer.

Electrochromism refers to a phenomenon in which optical properties (reflectivity, transmittance, absorption, and the like) of a material undergo a stable and reversible color change under the action of an applied electric field, and is visually represented as a reversible change in color and transparency. Materials with electrochromic properties are referred to as electrochromic materials.

When no voltage is applied across the transparent conductive layer (for example, when a voltage is applied in the left-right direction in fig. 6, the top end is connected to the positive electrode and the negative electrode on the inner and outer sides, respectively, or the top end is connected to the positive electrode and the negative electrode on the upper and lower ends (the inner and outer sides, respectively) during the application), the entire light-adjusting film is colorless. After application of a voltage, lithium ions stored in the ion storage layer are injected into the electrochromic layer through the electrolyte layer under the action of an electric field (tungsten trioxide WO)₃) In the lattice voids of the thin film, LiWO is formed_3-xResult in being W⁶⁺Reduction to lower valent W⁵⁺Electrons from W⁶⁺To W⁵⁺The interband transition of (a) absorbs the photon and causes the color change. WO₃The color change effect of the eye cream is dark blue, and the eye cream has a protective effect on eye health.

The transparent conductive layer is made of ITO (indium tin oxide) material. When the thickness is only hundreds of nanometers (less than 1 micron), the indium oxide has high transmittance and the tin oxide has strong conductive capability. Because the coating is very thin and the medium must be carried, the liquid crystal display usually uses ITO coated rear glass. The design selects low-resistance glass with the thickness of 0.4mm, and the glass with the thickness and the conductivity is generally used for the STN liquid crystal display and has high safety and reliability.

The light-adjusting membrane electrodes are positioned at two ends of the membrane and fixed near the upper edge and the lower edge of the glasses frame. One side of the light adjusting film is bonded to the eyeglass lens by OCA optical cement (film sticking method). The OCA is a special double-sided adhesive tape with optical transparency, is prepared by preparing an optical acrylic adhesive into a non-substrate, then respectively attaching a layer of release film to an upper bottom layer and a lower bottom layer, is a high-transparency double-sided adhesive tape without a substrate, and is commonly used for bonding mobile phones, touch screens and the like.

Voltage range applied to the light adjusting film: 0-3V, safety and reliability, low energy consumption, stepless adjustment of voltage, and uniform adjustment of light transmission intensity by the light adjusting film from transparency to opacity.

Further, after voltage is applied to the first light modulation film electrode, ions stored in the ion storage layer are injected into lattice gaps of the electrochromic layer film through the electrolyte layer under the action of an electric field, and electrons in the electrochromic layer generate interband transition to absorb photons to cause color change. Thus, the color of the light adjusting film and the lens can be changed by controlling the power supply or the voltage.
