Description

581674 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a dynamic vision training device implemented by using 稜鏡, and in particular, it can make the eyeballs move appropriately in the natural state, thereby preventing A device for deepening myopia and reducing myopia. [Prior technology] The structure of the eyeball is like a camera. The ciliary muscles inside the ciliary body are controlled by the thickness of the lens, so that it can be adjusted so that the image can be clear when viewed from afar. On the outside of the eyeball, there are six external eye muscles' to control the direction of eyeball rotation. Each of the six eyes in the two eyes has a coordinated function to look in the same direction and fix the same goal. When looking at a near distance, both eyes will automatically converge (convergence), and when looking at a distance, it will automatically diverge (Divergence) towards the same goal. This is complementary. Seeing clearly. Some of the striated muscles are located away from the ciliary muscles of the ciliary muscle. The two eyes are inside and when they are strengthened, and the two eyes are relaxed and tuned to the civilized youth. For example, the rigid image set and effect set of the two eyes There are far-sighted festivals, and within the homework will lead to outreach. Helps the eyelashes to reach the water, and the eyes and the hunger have become like this. This is the sun-like body of the eye-shaped muscles and the eye muscles. Shrinking makes the crystal abduction movement thinner. During the period of vision work, the computer looked far away by excessively shrinking the crystal, so that the body's understanding of the matter was adjusted. On the contrary, it could be seen that the continuous growth of the crystal and the electricity became visible. There is no truth. That is, both thicknesses make near objects help the eyelashes return. Increased ground, especially close-sightedness over time, has made it rigid. The initial method became thinner, and it was shaped because of the paste.

DESCRIPTION OF THE INVENTION (2) Myopia. Near-fat often begins squatting with membrane vision. Inflection: 因 ϊ f: f, can be divided into inflectional myopia and axiality, which makes the image u i 疋 ciliary muscles contract too much, causing the lens to be too large, but caused by the previous two. Axial myopia is caused by the crystalline lens ΐ #, the eye axis is too long, and the I 彡 # period is formed by the inflectional myopia that begins to be less than the omentum. Myopia :: Time 'and the internal and external eye muscles are still I-method myopia for a long period of close-up; after a moderate relaxation, the method gradually becomes the axis of the eye and gradually increases :, J near: ball: gradually To adapt to this state, the image that has evolved into the so-called axial near 2 can be more easily imaged on the net, that is, the eye f ^ myopia. These are the myopias that most people in myopia suffer from the acquired environment. : See, Caimu mutual cause is due to the deepening of inflectional myopia and axial myopia. If the axis length is not excessively increased, it is possible to restrain the human beings from belonging to two eyes side by side, A, whether it is seen far or near. :::: The species, the eyeball of this animal can only strengthen outward and / or inward Pendulum, that is, the inner set. ^ T: when the eye is more abducted than the distant parallel sight, ":: = ;; month household = the inner set effect. When the eye is" working "it has the opposite effect: it helps to adjust See the increase in °. And the facts of outreach. Therefore, it can help reduce the number of adjustments. This is the cause of the occurrence and deepening of vision in ophthalmology. Long-term excessive insets and adjustments are normal and near vision (people without myopia), but also nearsightedness.

Page 6 581674 __ _ · " " — V. When the invention is explained (3), why does it not lead to the formation of myopia? This is because the cause of myopia is: π long time multiplied by "fixed focal length", especially near focal length, caused by the multiplication of two factors. Normal vision, because it is less fixed for a long time, Therefore, the inner and outer eye muscles are very fresh, flexible, and not rigid, so they can look far and near freely.

The eye muscles are the same as those in other parts of the body, such as the arms or legs. If the arm is placed on the table for a long period of time in a fixed posture, the muscles on the arm will be sore and stiff, thus becoming inflexible. Conversely, muscle movements will not cause muscle soreness and stiffness. Therefore, the same is true for the inner and outer eye grabbing 'of the eyeball. To prevent myopia, we must be able to constantly change the focal length and move from time to time. Therefore, in order to prevent myopia, it is not necessary to completely give up the short-distance operation, but to enable the inner and outer eye muscles to flexibly expand and contract during the short-distance operation. In other words, to enable the eyeball to gather, outreach, adjust, and relax, the four movements can be exchanged in a short period of time. Do not fix it at a focal length and eye position for a long time. Myopia caused by the "habit of distance".

According to the foregoing principles, the inventor of this case filed an application for Invention Patent No. 9111607 4 to the Jun Bureau on July 19, 2011, entitled "Dynamic Lens Vision Rehabilitation Method and Device", One of them is to dynamically push one eye or convex eye in front of the user's eyes, repeatedly forcing the user's eyeballs to abduct, thereby achieving the effect of training eyes. However, although the method and device in this case can effectively achieve the goal of training eyeballs, there is still room for further improvement. For example, the 稜鏡 or convex 稜鏡 used in the case No. 91116074 has a fixed degree, so For eyeballs

In other words, when the prism or convex ridge moves in and out repeatedly, it will cause the eyeball to quickly tighten and relax the muscles to match the change in the degree of the mirror, so it is easy to increase the burden on the eyeball. [Summary of the Invention] In view of this, the present invention is to provide an adjustable shuttle mirror vision training device capable of gradually extending the user's eyeball to overcome the aforementioned disturbances.

Therefore, the main object of the present invention is to provide an adjustable vision training device that includes a variable degree of vision, and is arranged in front of the user's eyeball.

Yet another object of the present invention is to provide an adjustable vision training device including a variable degree of vision, which is arranged in front of a user's eyeball, so as to reduce the intensive effect of the eyeball when looking at the object and enhance the outreach effect. Make eyes

Page 8 581674 V. Description of the invention (5) The posterior pole of the ball and the optic nerve are pressed in the opposite direction, thereby reducing the effect of axial myopia. Yet another object of the present invention is to improve the health ^ ^ A ^ ★ Putian X1 ^ for an adjustable vision training device, which can be used by the user to automatically change from π »η _ ^. ^, ^. At first glance, the task of visual training is carried out without inconvenience to the user. [Embodiment] In the following, with reference to the drawings, a few preferred embodiments of the present invention will be described in detail for the purpose of explaining the present invention:% ^ ^ ^ BH f β t. I first print, please refer to the first and second drawings, the adjustable visual acuity training of the present invention is ..... by ^-1. The principle that the device does not count. Shown in the first figure is a normal person's eyeball 4 when looking at a nearby object B. At this time, the eyeball A is in an intensive state so that the eyes can be focused on the same body ^. According to the present invention, in order to correct the excessive concentration of the eyeball for a long period of time, the lens can be provided in front of the eyeball A with a lens or optical element that refracts light, such as 稜鏡 c or the aforementioned No. 91116〇74 For the convex ridge described in the case, this 稜鏡 c is set in such a way that the light incident from the object B into the eyeball A is refracted, as shown in the second figure, or the refraction state of the incident light is changed, and therefore changed. The angle of light f 'incident into the eyeball A forces the eyeball A to swing outward. By repeatedly moving 稜鏡 c to eyeball A as square, it can continuously change the angle of incidence of light, which can then force eyeball A to constantly change between the state of inset and pendulum, and achieve forced eyeball training. Purpose of vision. Next, referring to the third figure, as described in the aforementioned No. 91116074, this device can be made into a structure similar to glasses E for users to wear on their heads.

In the aforementioned case No. 9 1 1 6 0 7 4, a transmission mechanism is provided in the spectacle structure E, and the lens C is repeatedly moved in and out repeatedly, so that the eyeball A is repeatedly collected in and out. It varies between pendulums. However, as mentioned earlier, this operation method will cause the eyeball A to withstand an instantaneous change in sight. Although the training effect on the eyeball can also be achieved, the eyeball muscle must withstand large pressure changes. In this case, the inventor further improved such a vision training device, so as to eliminate the above-mentioned problems. Please refer to FIG. 4 and FIG. 5, which show a first embodiment of the adjustable 稜鏡 vision training device according to the present invention, which is marked with the reference numeral 100 in the drawing. This adjustable 稜鏡 vision training The device 100 includes a frame or a fixing member 102, which may be a type of a spectacle frame or a spectacle hanger (as shown in this example) or another type, as in the aforementioned case No. 9ΐ1ΐβ〇74 The head-mounted type, eye mask type, and desktop type are mentioned. A window 104 corresponding to the user's eyeball is provided inside the fixing member 102, and this window 104 can be two positions respectively provided on the fixing member 102 corresponding to the perforation of the eyeball, or can also be The large ventilated area shown in this example covers both eyes of the user. Within this window 104, the adjustable light refraction devices 106 of the present invention are respectively provided at the positions corresponding to the eyes of the user. In addition, there is also a driving device 108, such as an electric motor, in the fixed part 102, which is arranged between the adjustable light refraction devices 106 in this example, and is located in the window 104 However, the setting position of the driving device 108 is not limited to this. The driving device 108 is connected to an adjustable mechanism through a transmission mechanism 1 丨 〇, respectively.

581674 V. Description of the invention On the (7) type light refraction device 106, driven by the driving device 108, the adjustable light refraction device 10 can change its degree, or its refraction effect, that is, the incident light The first refraction state (which can be a non-refraction situation) is changed to the second refraction state, and then the angle of light incident into the eyeball is changed to achieve the aforementioned vision training effect. The adjustable light refracting device 1 0 6 includes a first lens 1 12 and a second lens 1 1 4. The first lens 1 1 2 is fixed on the fixing member 102 and cannot be moved, and the second lens 1 1 4 is movably set in the window 10 104 of the fixed part 102, and is connected to the driving device 108 via the transmission mechanism 110, which can be driven relative to the driving device 108 The first lens 1 1 2 moves, and $ further changes the spatial relationship between the first lens 1 12 and the second lens 1 1 4 to change the refraction caused when light passes through the two lenses 1 1 2 and 1 1 4 effect. In this example, the second lens 1 1 4 is pivotally fixed in the fixing member 102, and when the adjustable vision training device 100 is worn on the user's head D ( (As shown in the third figure), the pivot axis 1 1 6 of the second lens 1 1 4 is substantially vertical, and the inner edge 1 2 of the second lens 11 4 is the two second lenses 1 The opposite edges of 1 4 are connected to the transmission mechanism 1 1 0. Driven by the transmission mechanism 1 10, the second lens 1 1 4 can rotate around its pivot axis 11 16 to change the angle between the second lens 1 1 and the first lens 11 2 to form an ordinary optical structure, in other words The angle between the first lens 1 1 2 and the second lens 1 1 4 ^ can be changed from the first angle (which can be zero degrees) to a second angle different from the first angle by the rotation of the second lens 11 4 . Although the first lens 112 in this example is not movable, it can be designed to be movable if necessary.

Page 11 581674 V. Description of the invention (8) After connecting to the drive, the internal thread of the movable two lenses 12 2 is changed to change the linearity of the first lens and change the operation of the first lens. In this example, the transmission mechanism] 丨 〇 20, Straight = The output shaft of the motor of the device 1 ^ 08 or is driven by a horse to rotate in other ways. On the screw 1 20, a movable member 1 22 provided with a hole (not shown) is engaged with the thread. By the rotation of the screw 1 20, the member 1 2 bites a linear displacement of the axis of the screw 1 2 0.

The inner edge 1 1 8 of Π 4 is connected to the movable member in an appropriate manner. Therefore, when the screw 1 2 is rotated by the driving device 108, the movable member is converted into a second lens 1 1 4 around Its pivot axis 1 1 6 is angularly displaced to change the included angle of the second lens 1 1 4 with respect to the first lens ii 2. Therefore, the 稜鏡 -type optical structure composed of the lens 1 12 and the second lens jj 4 can shoot. The refraction effect of light. Because the rotation of the screw i 2〇 is continuous, the linear displacement of the movable member 12 is changed steplessly and the second lens i 丨 4 driven by it is also changed steplessly. The angle with respect to the first lens 112 can provide the effect of continuously adjusting the refractive effect. In this example, the axis direction of the screw 1 2 0 is substantially horizontal and is substantially perpendicular to the user's face. However, it can be understood that the setting direction and position must follow the position and direction of the driving device 108. Change, so it should not be limited to what is shown in this example.

In order to obtain the best refractive effect, the present invention further provides a flexible tube 1 2 4 between the first lens 1 12 and the second lens 1 1 4, which may be a bellows tube as in this example, or It is another type of hose, which forms a closed space between the first lens 112 and the second lens 114, which can be filled with a transparent fluid (not shown) with an appropriate refractive index.

Page 12 581674 V. Description of the invention (9) Now, the adjustable light refraction device 106 can provide the best refraction effect to achieve the desired vision training effect. The flexibility of the flexible tube 1 2 4 itself prevents it from interfering with the movement of the second lens 11 4. It should also be noted that, as the second lens 11 4 rotates, the space inside the flexible tube 1 2 4 partially expands and the other part shrinks.

The position of the pivot axis 1 1 6 of the two lenses 1 1 4 is preferably such that the total volume of the space inside the flexible tube 1 2 4 can be kept substantially constant when the second lens 1 1 4 is moved to avoid Improper changes in the pressure of the internal fluid cause injury. For example, as shown in this example, the pivot axis i6 can be set at a substantially middle position of the second lens 1 1 4. However, this is only a design choice and should not impose unnecessary restrictions on the case. In addition, in order to facilitate users to carry out daily routines, they can be equipped with the ^ modulation 稜鏡 vision training device i 〇〇, the first lens ii 2 (or ^ t = can be made into lenses with other optical effects, such as this Example-the mirror, the convex lens, which is different in the power chart of the convex lens, and the power is different: use this device to about + 0.25D to + 〇75T). 彳 9 彳 + i / look away On TV ...
