As is well known, people with short sight often look far with naked eyes, the glasses have great benefits for recovering the sight of the people, and for teenagers, the glasses can be lost very possibly after long-term training, so that the sight of the people is recovered to be normal.

The cause of myopia is: in a natural environment, a picture seen by a person is near or far, and the person can see clearly only by continuously participating in focusing adjustment while moving, so that ciliary muscles of the eyes can be exercised along with frequent actions of the person, and meanwhile, under the adjustment of the ciliary muscles, external scenes are clearly imaged on retinas through pupils and crystalline lenses. Nowadays, with the operation of modern screen products such as mobile phones and tablet computers for transmitting media information, most people stare at the screen for a very long time every day, and students can watch the screen for more than 8 hours. When the planar reading materials are read, the ciliary muscle rarely performs distant view focusing adjustment and is in close distance, so that the capacity of the ciliary muscle for adjusting distant view focusing is gradually dull, the eye muscle is stiffened, and the myopia is formed.

Detailed Description

The therapeutic apparatus for correcting myopia by staring at naked eyes of the present invention employs an optical imaging system, and the most basic beneficial effects (realized by the following embodiment 1) can be produced: the character pattern on the object target plate 3 arranged in the therapeutic apparatus 1 is imaged on the rear-stage reflector 4 (arranged in the therapeutic apparatus 1) in a manner that the opening angle of the entering human eye is adjustable, and the image imaged on the rear-stage reflector 4 is projected to the eyes of the staring person through a light-transmitting window 24 arranged on the shell 2 of the therapeutic apparatus 1. The therapeutic apparatus 1 can make the myopic eye patient draw out a short time every day and carry out the training of restoring the vision of the eyes in a naked eye gazing mode, during the training, the patient stands at a distance away from the light through window 24 and gazes at the image in the rear-stage reflecting mirror 4, the distance is preferably at the photopic distance or the far point position of the patient, at the moment, when the patient looks at the object, the ciliary muscle of the eyes of the patient is in a completely relaxed state, at the initial stage of the training, the image with a larger opening angle can be gazed, from the middle stage to the later stage, the image projected by the rear-stage reflecting mirror 4 can be gradually adjusted to the image with a smaller opening angle entering the eyes of the patient, the patient looks like seeing a distant object, the training is repeated, the ciliary muscle of the eyes of the patient can be exercised due to frequent activities, and the ciliary muscle can gradually restore the ability.

The beneficial effects that can be produced after the invention is further improved (realized by the following example 2) are that: the image of the parallel light projected by the rear-stage mirror 4 is a reduced image in which the field angle at which the image enters the patient's eye is small, i.e., compared with the character pattern on the object side target plate 3. Thus, the patient stands at the photopic distance or the far point position to stare at the object as if it were a far object, thereby leaving the patient's ciliary muscles in a substantially relaxed state. Also, by adjusting the amount of flare angle that the image enters the patient's eye, repeated training can result in better and faster recovery of the ciliary muscle's accommodative ability.

The noun notation:

a far point: when the radius of curvature of the two curved surfaces of the muscle relaxing lens in the eye is at its maximum, the distance from the object point, which can be imaged clearly on the retina, to the eye is called the far point.

And (3) near point: when the object moves from far to near gradually, the muscle is required to press the crystal to make the radius of curvature of two curved surfaces (mainly the front surface of the crystal) become smaller, when the object moves to a certain distance, the radius of curvature of two curved surfaces of the crystal is already minimized, if the object moves from this position to near, the object can not be seen clearly because the radius of curvature of the crystal is not reduced, and the distance from the object point to the eyes is called as the near point.

Distance of photopic vision: under proper illumination (50-100 lux), the normal eye can see objects 25cm in front of the eye without difficulty and is comfortable, and the distance is called the photopic distance of the eye.

Example 1

As shown in fig. 1 to 3, in this embodiment, the object space target 3 is disposed at the bottom in the housing 2, the rear-stage reflecting mirror 4 is a spherical mirror, and is disposed obliquely above the object space target 3, the object space target 3 is connected to the transmission mechanism 7, and the object space target 3 can move up and down in the housing 2 by adjusting the image distance adjusting member 5.

The curvature radius of the rear-stage reflector 4 is 180-.

The paraxial spherical refraction formula is as follows: (n '/s ') - (n/s) ═ n ' -n)/r;

n and n 'are refractive indexes of transparent media on two sides of the single spherical mirror interface respectively, s and s' are distances from an object and an image to the center of the interface respectively, and r is the curvature radius of the single spherical mirror.

When n ═ n, the single spherical mirror can be regarded as a spherical mirror, and in this case, the reflection formula of the spherical mirror in the paraxial region is: (1/s') + (1/s) ═ 2/r.

The included angle between the central normal of the rear-stage reflector 4 and the plane of the light-transmitting window 24 is 5-45 degrees. In this embodiment, the aperture area of the light-passing window 24 is large.

The object space target plate 3 is located between the object space focal plane of the rear-stage reflective mirror 4 and the rear-stage reflective mirror 4, that is, the image of the character pattern on the object space target plate 3 on the rear-stage reflective mirror 4 is an enlarged virtual image.

The distance between the object space target plate 3 and the rear-stage reflective mirror 4 is shortened or shortened by adjusting the image distance adjusting component 5, so that the opening angle of the virtual image entering the pupil of the human eye is changed.

By adjusting the angle adjusting member 6, the image on the rear-stage mirror 4 can be adapted to users of different heights to see the virtual image.

Example 2

As shown in fig. 4 to 8, in this embodiment, the object space target 3 is disposed inside the bottom of the casing 2, and the rear-stage reflective mirror 4 is a spherical or plane reflective mirror which is disposed outside the bottom of the casing 2 together with the object space target 3, that is, the object space target 3 is disposed in parallel with the rear-stage reflective mirror 4, and the light-transmitting window 24 is disposed at the bottom of the front surface of the front cover 21.

A catadioptric system (an optical system composed of a lens and a reflector is generally called as a catadioptric system) which is formed by designing and combining a plurality of optical lenses of a plane or spherical reflector, a spherical convex lens and a spherical concave lens according to an optical imaging principle is arranged on a light path which is positioned above the object space target plate 3 and the rear-stage reflector 4 and is arranged between the object space target plate 3 and the rear-stage reflector 4 in the shell 2.

In the embodiment, the character and pattern object points on the object space target plate 3 are projected out of the shell 2 by the rear-stage reflector 4 in a parallel light mode through adjusting the reflex system, namely, an image on the rear-stage reflector 4 is a reduced image compared with the character and pattern on the object space target plate 3, and the image is emitted in parallel light, so that a person feels that the image seen by the person is a distant object, and for a staring person, firstly, the opening angle of the image entering the pupil of the staring person is small, and the ciliary muscle of the eyes of the person is in a very relaxed state; secondly, aiming at the refraction characteristic of human eyes to light, the image formed by parallel light is emitted into human eyes and is easy to converge on retina through the refraction of the crystal, so that a staring person sees a clear image.

The catadioptric system that achieves the above objectives can be combined in several ways according to the optical imaging principle.

The present invention is illustrated by the following reflexive system:

the catadioptric system may be composed of a first convex lens (not shown), a first plane mirror 8 and an oppositely arranged telescope lens assembly. The rear-stage reflector 4 is a plane reflector, the object space target plate 3 is located on an object space focal plane of the first convex lens, the first plane reflector 8 is located above the first convex lens in an inclined manner, the telescope component (not shown in the figure) is a Keplerian telescope component or a Galileo telescope component, and the telescope component is located in a light path between the first plane reflector 8 and the rear-stage reflector 4.

In the catadioptric system, the first convex lens projects an object point on the object space target plate 3 to the first plane mirror 8 in a parallel light manner, and the plane mirror does not change the size of an image, only changes the direction of light, projects the image of the object point to the telescope component in a parallel light manner, and projects the image of the object point to the rear-stage reflective mirror 4 in a parallel light manner by the telescope component, so that the image formed by the object point of the character pattern on the object space target plate 3 is emitted out of the housing 2 in a parallel light manner by the light-transmitting window 24.

The telescope component is a Keplerian telescope or a Galilean telescope which is reversely arranged, and the reverse arrangement is as follows: the eyepiece in the Keplerian telescope or the Galileo telescope is set as an object side lens in the telescope component, and the objective lens in the Keplerian telescope or the Galileo telescope is set as an image side lens in the telescope component, so that the telescope component emits a larger image into a reduced image through the image side lens, namely, the object entering the human eye with a larger opening angle is converted into an image entering the human eye with a smaller opening angle.

Note that: conventional keplerian telescopes and galilean telescopes present an image of an object with a small opening angle entering the human eye at a distance in the human eye as a magnified image of the opening angle entering the human eye.

In the catadioptric system, the first plane mirror 8 and/or the telescope assembly can be connected with the image distance adjusting part 5, and the size of the image emitted by the rear-stage reflecting mirror 4 can be adjusted by the following single adjusting mode or combined adjusting mode:

the first adjustment mode is as follows: by changing the angle between the first plane mirror 8 and the optical axis of the first convex lens.

The second adjustment mode is as follows: by varying the distance between the first plane mirror 8 and the telescope assembly.

The third adjustment mode is as follows: by changing the distance between the telescope unit and the rear mirror 4.

The angle adjusting part 6 can be connected with the first plane reflector 8 or the rear reflector 4, and can adjust the included angle between the first plane reflector 8, the rear reflector 4 and the main optical axis.
