Device and method for automatically correcting myopia

Technical Field

Myopia has become an important issue affecting the health of people in China. Investigation shows that the incidence rate of myopia in the population of China is 33%, the number of myopia in the whole country is nearly 4 hundred million, and the number of myopia is the first world. The incidence rate of myopia of teenagers, which is a high incidence group of myopia, is as high as 50-60%, and China is one of the countries with the highest incidence rate of myopia in the world. Myopia occurs mostly because of too long anterior-posterior axis of the eyeball (referred to as axial myopia), followed by stronger refractive power of the eye (referred to as Qu Lvxing myopia).

The myopia vision correction mainly comprises the following two methods:

Frame glasses: this is the simplest, safe corrective appliance. Mild and moderate myopes may wear appropriate frame glasses to correct vision. The frame glasses need to be checked in a regular hospital, and a doctor prepares the glasses according to the myopia degree of a patient. The patient should review at least once a year and adjust the lens power in a timely manner. For a myopic patient in a child, at least one review every half year should be performed.

Corneal contact lens: including soft contact lenses, hard contact lenses, and cornea shaping lenses. The glasses can be worn on the eyeballs directly, and are more convenient than the frame glasses. However, if the eyes feel uncomfortable, the eyes should be immediately taken out so as not to damage the eyeballs.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As mentioned in the background art of the present application, the inventor found that the eye structure is shown in fig. 3, the refractive focal position of the normal eye is shown in fig. 4, the refractive focal position of the myopic eye is shown in fig. 5, and the existing myopic vision correction method adopts a certain device (such as a concave lens) to change the focal position of the incident eyeball light, so that the external scene is just imaged on the retina to achieve the effect of correcting the vision (such as fig. 6), but the original vision cannot be automatically corrected, and the vision correction is a long-term physiological training activity due to the physiological characteristics of the human body, so that the prior art cannot orderly perform the vision correction, and has a certain defect.

In order to solve the defects, the application discloses a device and a method for automatically correcting myopia, which can sequentially and asymptotically assist a user to automatically correct the original vision through a telescopic transmission mechanism, a signal control module and a distance measuring mechanism.

How the above technical problems are solved by the scheme of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, in an embodiment of the present application, an apparatus for automatically correcting myopia includes two symmetrical lens frames 1, a lens frame 2 is disposed between the two lens frames 1, and two horizontally symmetrical lenses 3 are embedded on an outer side surface of the lens frame 2; a telescopic transmission mechanism is arranged between one side inside the glasses frame 1 and the glasses frame 2, a signal control module is arranged on the other side inside the glasses frame 1, and a distance measuring mechanism is embedded in the middle of the outer side face of the glasses frame 2. The application has the functions of automatically correcting and recovering vision through the telescopic transmission mechanism, the signal control module and the distance measuring mechanism, and the vision correction process is gradual. The application can adjust the state of the telescopic transmission mechanism according to the state of the user and the body position distance, thereby determining the light focus distance; wherein the focus of the working state is on the retina; the foci in rest state are spaced about 0.5-1 mm from the retina, thereby guiding the eye ciliary muscle to contract and relax according to the vision automatic feedback mechanism. After the first fine tuning training is effective, the focal distance is increased for the second time, and a bit of distance is increased each time, and when the training is effective, the position of the retina with normal focus is restored.

The visual automatic feedback mechanism of the eye is a complex physiological process involving interactions between the eye, the nervous system and the brain. This process ensures that we can accurately and quickly perceive and adapt to changes in the surrounding environment. First, as light enters the eye, it passes first through the cornea and lens, and these transparent structures act to refract and focus the light. The light is then projected onto the retina, which is a photosensitive surface inside the eye. Here, the light is converted into a neural signal. Photoreceptor cells on the retina (mainly rod cells and cone cells) are responsible for receiving these light stimuli and converting them into electrical signals. These electrical signals are then transmitted through the optic nerve to the visual cortex in the brain. In the visual cortex of the brain, these electrical signals are further processed and decoded to form a visual image that we perceive. In this process, the brain will modify and interpret the visual signal based on past experience and current environmental information. It is critical that the visual automatic feedback mechanism plays an important role in this process. When the eye senses a change in light or movement of an object, it rapidly adjusts the focal length and gaze direction to ensure that the image is clearly imaged on the retina. This adjustment is achieved by muscles within the eye whose movements are in turn controlled by instructions from the brain. Furthermore, the visual automatic feedback mechanism involves coordination of eye movements. When we look at an object, the eyes will automatically track the movement of the object, keeping the object in the center of the field of view. This coordination of eye movement is achieved by a close fit between the brain and eye muscles. In summary, the visual automatic feedback mechanism of the eye is a complex physiological process involving interactions between the eye, the nervous system and the brain. This mechanism ensures that we can accurately and quickly perceive and adapt to the visual environment, so that efficient visual communication and information acquisition can be performed in daily life.
