Description

Vision correction instrument

Technical Field

The invention relates to the field of vision correction, in particular to a vision correction instrument.

Background

Myopia is listed as one of three diseases in the world, the number of myopia people in China is approximately 4 hundred million, wherein the number of myopia people is approximately 2.7 hundred million, and the number of myopia people is approximately 6 percent each year. The incidence rate of myopia of students in China is second in the world, the number of students is first in the world, and the incidence rate of myopia is as high as 50% -60%. The investigation shows that the vision morbidity of primary school students in China is about 28%, that of junior middle school students is about 60%, that of senior middle school students is about 85%, and the average annual increase is about 125 ℃. Myopia is an ophthalmic disease that, if not treated or prevented in a timely manner, can exacerbate the degree of myopia, which can even lead to blindness in severe cases. Medical practice has shown that people with high myopia are likely to develop eye diseases that cause blindness, such as cataract, glaucoma, and retinal damage, over time. Therefore, the prevention and treatment of myopia of children and teenagers are more and more concerned by students, parents and society.

The formation cause of the myopia is quite complex, and the summary is not influenced by the congenital genetic cause and the acquired environmental factor, wherein the former accounts for 20 percent, and the latter accounts for 80 percent. The influence of acquired environmental factors is the main cause of myopia, especially, in the growth process of teenagers, if the teenagers pass through myopia objects for a long time, the eyes are over-tense in adjustment, pseudomyopia is formed, and if the regulation is not improved, true myopia is further formed. The time for modern people to use electronic equipment is increased, so that the eye fatigue, blurred vision and dry eyes can be caused due to overlong eye using time, and the myopia can be caused due to the fact that the light is turned off to play a mobile phone at night, and the fatigue of the eyes is easily caused due to over-strong light. Generally, the onset of myopia is mainly in the following stages: the kindergarten is in youth of college, primary school grade one, primary school grade three, primary school grade five and age over 12 years old.

At present, a plurality of methods for treating eye vision diseases such as myopia, amblyopia and the like are available, and the methods mainly comprise traditional Chinese medicine massage therapy, pharmacotherapy, acupuncture therapy, physical therapy, surgical treatment and the like, the treatment effects of various therapies are different, the requirements of applicable patient population conditions are also different, some therapies play a role in relieving and recovering vision, some therapies improve vision within a period of time, but after stopping therapy or stopping therapy for a period of time, the vision quickly rebounds, even some therapies are more serious than before therapy, and some therapies also bring about other complications of eyes. In summary, no therapeutic apparatus has been known so far which is effective for ophthalmic diseases such as myopia and the like, has stable effect after treatment, and can cure or partially cure ophthalmic diseases without sequelae.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the present invention provides a vision correction apparatus, which comprises a housing, wherein the housing is composed of a base 1 and an upper shell 2 arranged on the upper portion of the base, and a closed space is formed between the base 1 and the upper shell 2. An eye patch 3 is arranged on the front end face of the shell, the eye patch 3 protrudes out of the front end face, two view ports 4 are arranged on the eye patch 3 at intervals, and a bonding part which is bonded with the human face is arranged on the front end face of the eye patch 3. The patient sits right in front of the correction instrument, the face is attached to the eyeshade, and the two eyes are respectively opposite to the viewport. The eye shade is preferably set to be black, and the light-tight material is adopted, so that the two eyes of the patient only receive light information sent out from the interior of the correction instrument, and further the eyeball of the patient is trained and treated.

As is well known, the normal imaging principle of the eye is: light rays (object) → cornea → pupil enlargement or reduction according to the intensity of light rays → thickening or thinning (accommodation) of the lens according to the distance and the proximity of the object position → focusing the object on the retina to image → through the visual conduction system → to the cerebral cortex → forming clear vision. The main causes of myopia of the eye are: myopia is the cause of the eyes adapting to the environment, and is the symptom that the eyes cannot see distant objects and can see close objects clearly. When a distant object is seen on the premise of resting refraction, the curvature of a curved surface is increased due to the automatic accommodation failure of a crystalline lens caused by long-term near vision, the object cannot converge on the retina, and a focus is formed in front of the retina, so that vision deformation is caused, and the distant object is blurred. The myopia is divided into refractive myopia and axial myopia, wherein the refractive myopia is the most extensive and accounts for more than 85%. When the eyes look near for a long time, ciliary muscles for adjusting the change of the curvature of the crystalline lens must pull the crystalline lens for a long time to enable the curved surface of the crystalline lens to become convex so as to adjust the focal length to enable the focal point to converge on the retina and achieve the purpose of seeing objects at the near position clearly. In order to adapt to approach, the eye relieves the load of ciliary muscles to cause ciliary muscle spasm, so that the lens loses elasticity after becoming convex to form 'solidification', and the eyeball is driven to change from a round shape to an oval shape to lengthen the axis of the eye. After the axis of the eye is lengthened, the retina moves backwards, and the ciliary muscle can make the focus fall on the retina without adjusting the curvature change of the curved surface of the crystalline lens, but when the eye looks away, the axis of the eye is lengthened and the ciliary muscle is spastic, so that the crystalline lens is cured, the elastic adjustment is lost (the curvature of the curved surface is automatically changed to adjust the distance and the near focal distance when the eye looks away and near objects), the imaging focus is always in front of the retina, and the object in the distance is not seen clearly, so that the myopia is formed. The reason for the formation of presbyopia is: the formation mechanism of far vision is similar to that of near vision, that is, the curvature of the curved surface of the crystalline lens is increased, the imaging focus is always behind the retina, and therefore objects far away can be seen clearly but the eyes cannot see the near, so that the far vision is formed.

The shell is provided with a power switch button 15, a mode selection button 16, a start-stop button 17, an external power socket, an LED lamp brightness adjusting knob and other operation keys, so that a patient or a doctor can conveniently operate the instrument.

The invention is characterized in that a box-type inner container 5 is arranged in a closed space, the box-type inner container 5 is in a cuboid shape, and the box-type inner container 5 is formed by welding stainless steel plates with the thickness of 1 mm. Two first round holes 6 which are opposite to the view port 4 in position and are arranged at intervals are arranged on the front end face of the box-type inner container 5, the center distance of the two first round holes 6 is 63 mm, the diameter of each first round hole is 18 mm, transparent baffles 7 are arranged at the positions of the two first round holes 6, the transparent baffles 7 are in sealing connection with the box-type inner container 5, and the front end face of the box-type inner container is preferably made of PMMA acrylic materials or glass materials. The front inner side surface and the rear inner side surface of the box-type inner container 5 are both provided with a reflective lens 8, and the reflective lens 8 on the front inner side surface is provided with two second round holes 9 which are arranged at intervals and are opposite to the first round holes 6. The sight line of the patient sequentially penetrates through the view port, the first round hole and the second round hole to look into the closed space.

The invention is provided with the reflecting plates 10 on the left and right inner side surfaces and the inner side surface of the bottom of the box-type inner container 5, preferably, the reflecting plates 10 are white reflecting plates with the thickness of 1 mm. The inner side surface of the bottom is provided with a marker 11, and the marker is selected from a bright-colored object and is fixedly placed on the inner side surface of the bottom. The LED lamp panel 12 is arranged on the inner side surface of the top of the box-type inner container 5. Preferably, the LED lamp panel 12 is composed of 1080 LED lamp beads. The LED lamp panel 12 is provided with a plug wire interface, the top of the box-type inner container 5 is provided with an opening 13, the plug wire interface extends out of the opening 13, and the plug wire interface is connected with a built-in power supply, a circuit board and the like through a lead to control the adjustment of the brightness and the frequency of the LED lamp panel.

The operation process of the invention is as follows: the LED lamp panel works to emit light when the start-stop switch is pressed, the interior of the box-type inner container is lightened, and due to the fact that the front end face and the rear end face of the box-type inner container are provided with the reflecting lenses and reflect mutually, an inner cavity of the box-type inner container seen by human eyes is actually an infinitely extending space channel, and markers which are placed in the box-type inner container and have bright colors also extend infinitely from near to far. When a myopia patient looks at a distant object to the greatest extent, the iris sphincter of the eye is tense, the pupil is contracted, the ciliary muscle is relaxed, the zonule of the ciliary muscle connecting the ciliary process and the crystalline lens is tensed to drive the curvature of the curved surface of the crystalline lens to be increased (namely the thickness of the crystalline lens is increased), the refractive index is weakened, and the imaging focus of a distant object gradually approaches the retina. Meanwhile, the first-class lamp beads on the LED lamp panel are alternately lightened at a continuous conversion frequency, so that a dioptric system of eyes alternately receives the action of strong light and weak light, pupils (the adjustment reaction of pupils to light, strong light → contraction of sphincter pupils → pupil contraction, weak light → contraction of mydriasis opening machine → mydriasis) are alternately contracted and enlarged, and the vitality of active cells of ciliary muscles is activated to drive the curvature of the curved surface of the crystalline lens to be alternately changed. Thus, an adult carries out 15 minutes each time (10 minutes each time for a teenager), assists the massage of the eyes to promote the blood circulation of the eyes and the activity improvement of lacrimal glands and aqueous humor systems, and gradually changes the spasm condition of ciliary muscles and recovers the elastic activity of the ciliary muscles to drive the recovery of the automatic adjustment function of the elasticity of crystalline lenses after carrying out multiple process cycles, so that the myopia degree of the eyes is gradually weakened to be recovered to be normal.

The vision correction of the hyperopic patient is the same as the myopia correction process, except that the hyperopic patient needs to see a near object in the box channel every time and relatively dims the brightness of the LED lamp. After many cycles of this procedure, the degree of distance vision is diminished and restored to normal.

The countdown display screen 14 is arranged on the shell and used for displaying the use time, so that the medical care personnel can conveniently control the countdown display screen.

The invention mainly utilizes the principle of optical imaging, and makes the ciliary muscle of the eye contract and relax through objects with different distances in an infinitely extending space channel arranged in an eye watching instrument, thereby making the crystalline lens become thicker and thinner, recovering the elasticity of the crystalline lens, gradually making the image fall on the retina, and adjusting an abnormal dioptric system to gradually recover to a normal state through the change of light flicker frequency, thereby continuously improving and recovering the eyesight of myopia, amblyopia, hyperopia and the like so as to achieve the normal state.
