  The present invention relates to a visual acuity recovery training apparatus and a visual acuity recovery training control program for recovering visual acuity that has decreased due to myopia, presbyopia, and the like by training of an imaging adjustment function of an eye.

2. Description of the Related Art In recent years, a vision recovery training apparatus has been used in order to recover the decreased visual acuity due to a decrease in the imaging adjustment function of the eye due to adjustment tension or weakness of the eye adjustment muscle (ciliary muscle).
In such a visual acuity recovery training apparatus, it is particularly important that the user concentrates only on the visual acuity recovery training image and stabilizes the degree of concentration, thereby reducing fatigue due to training.

  For example, Patent Literature 1 and Patent Literature 2 describe a vision recovery training image displayed on a display unit installed inside a housing according to an optical distance between a user's eye position and a display unit position. An eyesight recovery training device (eyesight improving device) that changes the display size of (mark, target) is disclosed. Specifically, as the target moves, the target graphic is displayed larger when the target is far away so that an image of a certain size is formed on the retina of the user while the target is moving. When there is a target, the target figure is displayed small.

As a result, the size of the target figure changes in proportion to the distance between the target and the eyepiece, so it is easier to focus on the figure when the target moves, and more effective training is performed. Can do.
Japanese Patent No. 3766682 (registered on February 3, 2006) Re-published patent WO 2006/006563 (Internationally published on January 19, 2006)

However, the conventional vision recovery training apparatus has the following problems.
That is, in the visual acuity recovery training device disclosed in the above publication, since the size of the target figure is changed so that an image of a certain size is formed on the retina of the user during the movement of the target, If the movement of the target is stopped for a predetermined time in order to promote the user's concentration at the far point, the stimulus of the target change may be lost and the user's consciousness may be distracted. In this case, the concentration of the user is easily interrupted, and there is a possibility that the effect of training is reduced.

  An object of the present invention is to provide a vision recovery training device and a vision recovery training control program capable of performing more effective training without interrupting the concentration of a user during training.

  A visual acuity recovery training device according to a first aspect of the present invention is a visual acuity recovery training device that trains an imaging adjustment function of an eye, and includes a display unit, a moving unit, and a control unit. The display unit displays an image for visual acuity recovery training. The moving unit reciprocates the image displayed on the display unit between the far point and the near point. The control unit controls the display unit to change the image when the image moves between the far point and the near point.

  Here, for example, by displaying a predetermined vision recovery training image on a display unit installed inside the housing or the like, the user can look away inside the housing while moving the image away or closer. In the visual acuity recovery training apparatus that performs the imaging adjustment training of the eyes, display control is performed so that the image that moves between the far point and the near point changes.

  Here, the display control for changing the image for eyesight recovery training is, for example, display control such as a moving image of an animal moving continuously when the image for eyesight recovery training is a picture of an animal, This includes display control that changes information to create one word. The image for visual acuity recovery training includes figures such as circles, triangles, quadrangles, and ring shapes, alphabets, hiragana, katakana, photographs, animations, and the like. As a display unit for displaying such an image, an electronic display unit such as a liquid crystal display, an organic EL display, or a CRT display can be used.

  Further, the far point which is the farthest point in the range in which the image reciprocates is that the thickness adjustment of the lens for adjusting the thickness by the relaxation and contraction of the ciliary muscle (ring-shaped muscle) is not performed at all. An external point that forms an image on the central fovea of the retina. On the other hand, the near point, which is the closest point in the range in which the image reciprocates, refers to an external point imaged in the fovea of the retina with the eye lens thickness adjustment being maximized. The near point and the far point may be set as one point at a predetermined position where the distance to the trainee is close and one point at a predetermined position farther from the one point.

  According to the visual acuity recovery training device according to the present invention, regardless of the user, it is possible to maintain the concentration during the exercise as long as possible and obtain a sufficient effect by the visual acuity recovery exercise.

The visual acuity recovery training apparatus according to an embodiment of the present invention is described below with reference to FIGS.
[Configuration of overall vision recovery training apparatus 10]
As shown in FIGS. 1 and 2, the visual acuity recovery training device 10 according to the present embodiment is a mark (an image for visual acuity recovery training) displayed on the display unit 20 in the casing unit 11 that reciprocates in a predetermined direction. ) This is a device for recovering the visual acuity that has decreased due to myopia or hyperopia (presbyopia) by gazing at 20a (see FIG. 4). Specifically, the display unit 20 is reciprocated between a near point and a far point set for each user, and the mark 20a moves from the near point to the far point, or from the far point to the near point. In doing so, the user performs the training while paying attention to the moving mark 20a.

  The far point is an external point imaged in the fovea of the retina when the lens thickness of the eye is not adjusted at all, and the near point is the adjustment of the lens thickness. An external point that forms an image in the fovea of the retina when extreme. The near point and the far point may be set as one point at a predetermined position where the distance to the trainee is close and one point at a predetermined position farther from the one point. Even in this case, an effect as a visual acuity recovery training can be obtained.

  Further, in this embodiment, as the mark 20a for vision recovery training, a picture with the owl facing the front is used as shown in FIG. 4 or the like, but it is easy for the user to focus on during training. Any shape or color is acceptable.

  As shown in FIGS. 1 and 2, the vision recovery training device 10 is provided in a substantially rectangular parallelepiped casing 11, an eyepiece 12 provided on a wall surface of the casing 11, and the casing 11. The moving unit 13, the floor surface 14, the opening 15, the illumination unit 16, the display unit 20, the audio output unit 49, and the control unit 40 are provided.

  The eyepiece unit 12 is a peephole for viewing the display unit 20 (mark 20a (see FIG. 4)) that moves in the housing unit 11 in a state in which a user who performs a vision recovery training is focused. . And although the two eyepiece parts 12 are provided in this embodiment, it is sufficient that at least one eyepiece part 12 is provided. Further, the eyepiece unit 12 is provided with a shutter (not shown) and the like, and by closing one side of the eyepiece unit 12 with the shutter or the like, it is possible to carry out vision recovery training alternately for each eye.

  The moving unit 13 is installed in a space below the floor surface 14 in the housing unit 11, and includes a motor 30, a support unit 21, a pedestal unit 22, and a screw 23. The moving unit 13 is controlled by the control unit 40 to drive the motor 30 and reciprocates the display unit 20 in a predetermined direction.

In the floor surface 14, an opening 15 for moving the support portion 21 that supports the display portion 20 is formed. The opening 15 is formed along the direction connecting the near point and the far point.
The illumination unit 16 is an illumination device installed on the wall surface on the side where the eyepiece unit 12 is provided so that the user can easily see the mark 20 a displayed on the display unit 20 from the eyepiece unit 12. It is preferable that the illumination unit 16 can be set to an appropriate brightness according to the type, display state, display color, and the like of the mark 20a on the display unit 20.

  The display unit 20 is disposed within a range that can be viewed by the user through the eyepiece unit 12, and displays a mark 20a described later. The display unit 20 is supported from the pedestal unit 22 by a bar-shaped support unit 21, and is set in advance for each pedestal unit 22 fitted to the screw 23 by rotating the screw 23 in a predetermined direction by the motor 30. It moves back and forth between the near point and the far point. Note that a liquid crystal display is used as the display unit 20, and the size and shape of the mark 20 a can be controlled and colored by the control unit 40.

  The voice output unit 49 is a device that outputs voice information such as a speaker. For example, a voice such as a whistle that notifies the start timing of training, or voice information corresponding to the mark 20a (for example, when the mark 20a is an alphabet, (Pronunciation of English words, etc.) is output into the casing 11.

  As shown in FIGS. 2 and 3, the control unit 40 is connected to the display unit 20, the motor 30, and the input unit 31, and controls the display of the mark 20 a on the display unit 20, and the moving speed of the display unit by the moving unit 13. Control the movement direction and the like. The configuration of the control unit 40 will be described in detail later.

(Control unit 40)
As shown in FIG. 3, the control unit 40 includes an input control unit 41, a display control unit 42, a storage unit 43, a drive control unit 44, a movement direction control unit 45, a position control unit 46, a speed control unit 47, and a voice control unit. 48.

  The input unit 31 is an input switch or the like, and control information related to the mark 20a (image for vision recovery training (figure)) displayed on the display unit 20 and position information related to near points and far points described later are used to restore visual acuity. It is input in advance before the start of training.

  In addition, although the positional information regarding a near point and a far point is shown as the distance from the eyepiece part 12 to the display part 20, since there are individual differences depending on the user, it is necessary to adjust for each user. Specifically, the near point is in the range of 100 to 200 mm from the eyepiece 12, and the far point is in the range of 500 to 1000 mm from the eyepiece 12, and appropriate numerical values are input for each user.

  The input control unit 41 is connected to the display control unit 42 and the drive control unit 44, and relates to control information such as a mark 20 a (display graphic) in the display unit 20 input to the input unit 31 and the motor 30. Control information, audio information output from the audio output unit 49, and the like are transmitted.

  Based on the control information received from the input control unit 41, the display control unit 42 controls the display unit 20 to display the mark 20a having an appropriate size or change the display of the mark 20a. In addition, the display control unit 42 controls the display unit 20 to display information regarding the distance between the eyepiece unit 12 and the display unit 20 acquired by the position control unit 46. Based on the input control information, the display control unit 42 selects a predetermined graphic to be used as the mark 20a from graphic data stored in the storage unit 43 in advance, and displays information on the selected graphic and its size. Displayed on the unit 20. Thus, by displaying information such as the distance from the eyepiece unit 12 to the display unit 20 and the size of the graphic such as the mark 20a, as a result of the vision recovery training, which graphic can be seen well to what distance. It is possible to make the user recognize whether or not Therefore, it is possible to make the user recognize the effect of the visual acuity recovery training and motivate the next visual acuity recovery training.

  Further, the display control unit 42 controls the display unit 20 so as to change the size of the graphic displayed on the display unit 20 in proportion to the distance between the eyepiece unit 12 and the display unit 20. Specifically, as shown in FIG. 6, the display control unit 42 displays a small mark 20a near the near point, and the display unit 20 moves away from the eyepiece unit 12 from the middle point toward the far point. As the time goes, the display unit 20 is controlled so that the mark 20a is gradually displayed larger. On the contrary, when the display unit 20 is moved from the far point to the near point, as shown in FIG. 8, the display control unit 42 displays the mark 20a in the vicinity of the far point and displays the mark 20a as the near point is approached. The display unit 20 is controlled so as to display small. As a result, a mark 20a having almost the same size is always displayed on the retina of the user who performs the vision recovery training regardless of the distance between the eyepiece 12 and the display unit 20. In this way, if the size of the image formed on the retina of the eye is kept substantially constant, the amount of visual information entering the brain is reduced, so that the user can easily focus the eye on the mark 20a. For this reason, the user who performs visual acuity recovery training makes it easy to see the mark 20a and can perform the visual acuity recovery training in a state of being concentrated on the mark 20a. As described above, even when the size of the mark 20a displayed on the display unit 20 is controlled, the user can operate the imaging adjustment function to focus the eyes on the figure. Therefore, even if the size of the mark 20a is changed during the visual acuity recovery training, the visual acuity recovery effect is not impaired.

  Furthermore, the display control unit 42 also controls the color of the mark 20a displayed on the display unit 20 and the background 20b thereof. Data relating to the color of the mark 20a and the background 20b is stored in the storage unit 43 in advance. The display control unit 42 acquires data related to the color of the mark 20 a based on the control information input from the input unit 31.

  In addition, when the display control unit 42 selects any one of red, green, and blue as the color of the mark 20a and black as the color of the background 20b, the user can easily concentrate on the mark 20a. This is because the photoreceptor in the retina of the human eye consists of a cone that distinguishes light and darkness from a cone that has absorption characteristics for light of each of the three colors red, green, and blue. This is because red, green or blue shapes are easy to see due to the characteristics of the receptor. Further, by making the background 20b black, it is possible to further easily identify the mark 20a, and to make it easier for the user who performs the vision recovery training to concentrate on the mark 20a.

  The storage unit 43 stores, as the mark 20a displayed on the display unit 20, information on a plurality of shapes such as graphics, characters, symbols, images, etc., color information on graphics and backgrounds, and the like. In addition, the storage unit 43 stores information on the distance between the near point and the far point set for each user who performs the vision recovery training, and the user sets the near point previously set when starting the vision recovery training. Information on the distance of the far point can be read from the storage unit 43 and used.

  The drive control unit 44 controls the motor 30 that drives the display unit 20 by the movement direction control unit 45, the position control unit 46, and the speed control unit 47. Specifically, the movement direction control unit 45 controls whether the display unit 20 moves in the direction from the far point to the near point or the direction from the near point to the far point. The position control unit 46 controls the position of the display unit 20 and the positions of far points and near points set and input from the input unit 31. The speed control unit 47 controls the moving speed of the display unit 20 that moves with the rotation of the screw 23 by controlling the number of rotations of the motor 30.

  When the activation signal of the vision recovery training device 10 is input from the input unit 31, the movement direction control unit 45 controls the movement direction between the far point and the near point of the display unit 20. Note that the initial position of the display unit 20 at the start of training varies depending on whether the visual acuity recovery training for myopia or the visual acuity recovery training for hyperopia is performed. For this reason, what is necessary is just to set the first moving direction of the display part 20 according to the content of visual acuity recovery training. For example, when the visual acuity recovery training for myopia is performed, the initial position of the display unit 20 is a near point, so the display unit 20 can be displayed at any position when the activation signal is input. The motor 30 is controlled so that the unit 20 moves toward the near point.

  The position control unit 46 appropriately controls the distance from the eyepiece unit 12 to the display unit 20 based on, for example, the number of revolutions of the motor 30. The distance from the eyepiece unit 12 to the mark 20a on the display unit 20 is input to the display control unit 42 and displayed on the screen of the display unit 20 together with the mark 20a.

  The speed control unit 47 can change the moving speed of the display unit 20 that reciprocates between the near point and the far point continuously or stepwise. When changing the moving speed stepwise, for example, the user is best suited to his / her own moving speed from 10 mm / sec, 20 mm / sec, 40 mm / sec, 80 mm / sec, 160 mm / sec, 250 mm / sec The moving speed can be selected. On the other hand, when the moving speed is continuously changed, the user can make a fine adjustment of the moving speed optimum for the user. Such a moving speed of the display unit 20 may be input directly from the input unit 31 by the user.

  The control outputs of the movement direction control unit 45, the position control unit 46, and the speed control unit 47 are input to the motor 30 that is driving means, and predetermined control is performed. When the movement direction control unit 45, the position control unit 46, and the speed control unit 47 are combined to vibrate back and forth in small increments when the display unit 20 moves, the mark displayed on the display unit 20 by the user This makes it easier to focus the eyes on 20a and to determine whether or not the eyes are in focus.

  The voice control unit 48 controls voice information output from the voice output unit 49 such as a speaker in accordance with the type of the mark 20 a displayed on the display unit 20, the changing timing, the training start timing, and the like.

  Here, in the visual acuity recovery training device 10, since it is necessary to secure a distance from the eyepiece 12 to the far point in the housing 11, the depth is usually about 550 to 1050 mm, and the device is enlarged. . Therefore, by providing a convex lens in the eyepiece 12, the depth can be reduced and the apparatus can be downsized.

<Outline of vision recovery training>
The user looks at the mark 20a displayed on the display unit 20 with both eyes or one eye while keeping his eye on the eyepiece 12. At this time, the user concentrates on the mark 20a so as to make it clearly visible, and focuses the eyes. In this manner, with the user's eye focused on the mark 20a, the user's eye ciliary muscles and pupils are repeatedly moved back and forth between the near point and the far point. The imaging adjustment function of the eye such as convergence / divergence can be operated to improve the imaging adjustment function of the eye.

  This makes it possible to clearly see objects that have been difficult to see so far, such as distant objects in the case of myopia and nearby objects in the case of hyperopia. In this way, the curvature control tissue of the lens such as ciliary muscles is moved, and the pupil diameter is adjusted and the whole eyeball including the retina is moved to activate the function of the eye. Can be

  The movement of the mark 20a between the near point and the far point described above is preferably performed, for example, 20 round trips as one set, and 2 to 3 sets about twice a day with a break. Thereby, it can prevent that it becomes dry eye by long-time training.

  In addition, even after watching a computer display for a long time or reading a book for a long time, the device functions for eyes by performing ciliary muscle movement, pupil adjustment, vergence / divergence. Can be recovered.

<Control of vision recovery training for myopia>
In the visual acuity recovery training apparatus 10 of the present embodiment, when performing visual acuity recovery training for myopia, as shown in FIG. 6, while controlling the display of the mark 20a on the display unit 20 to be changed, FIG. Processing is performed according to the control flow as shown in FIG.

Specifically, in step S <b> 1, first, the user presses a vision recovery training start button in order to perform a vision recovery training for myopia.
In step S2, the display control unit 42 controls the display unit 20 to display the mark 20a read from the storage unit 43.

  In step S <b> 3, the display unit 20 is moved to the vicinity of the near point that is the initial position of the visual acuity recovery training for myopia by the movement direction control unit 45 and the position control unit 46 included in the drive control unit 44. When the visual acuity recovery training start button is pressed, if the display unit 20 is in the vicinity of the near point, the display unit 20 may wait as it is. Moreover, about the process of step S2 and step S3, you may be performed simultaneously in parallel.

  In step S4, as a cue to start the training, for example, a whistle sound is output from the sound output unit 49 such as a speaker to cause the user to recognize the start of the visual acuity recovery training, and a certain mark 20a (see FIG. 4) is displayed. The displayed display unit 20 is moved at a predetermined speed from the near point to the far point (outward path). At this time, as described above, the display control unit 42 performs control so that the size of the mark 20a displayed on the display unit 20 changes. Specifically, according to the position of the display unit 20, that is, the distance from the eyepiece unit 12 to the display unit 20, the mark 20 a is displayed so that the mark 20 a having a substantially constant size can be seen from the user during training. Change the size of.

  In step S5, the display unit 20 stopped at the far point is moved from the far point to the near point (return path). In the visual acuity recovery training for myopia, the mark 20a may remain displayed or may not be displayed when the display unit 20 moves on the return path side.

  In step S6, it is confirmed whether or not the number of reciprocating movements of the display unit 20 has exceeded a predetermined threshold value (for example, 10 reciprocations in the case of 20 reciprocations for one set). Here, if the predetermined threshold is not exceeded, step S4 to step S5 are repeated. And when it exceeds a predetermined threshold value, it progresses to Step S7.

  In step S7, when the display unit 20 displaying the mark 20a is moved from the near point to the far point at a predetermined speed, the display of the mark 20a is controlled to change. Specifically, as shown in FIG. 6, the owl picture as the mark 20a gradually turns backward, and the display changes to look back again in the vicinity of the far point. As a result, even when a child or the like is a user, the training effect can be improved more than before by keeping watching the mark 20a in a concentrated state without getting tired of continuing to look at the mark 20a during training. Can do.

  In step S7, as in step S4 described above, the size of the mark 20a is set in accordance with the position of the display unit 20 so that the mark 20a having a substantially constant size can be seen from the user during training. Change (see FIG. 6).

  In step S8, the display unit 20 stopped at the far point is moved to the near point. Also in this case, in the visual acuity recovery training for myopia, when the display unit 20 moves on the return path side, the mark 20a may remain displayed or may not be displayed.

  In step S9, it is confirmed whether or not the display unit 20 has reciprocated a predetermined number of times (for example, 20 times in the case of one set of 20 reciprocations). Here, when the predetermined number of times has not been reached, after repeating steps S7 to S8 until the predetermined number of times is reached, the training is ended.

  In the visual acuity recovery training device 10 of the present embodiment, as described above, when the visual acuity recovery training for myopia is performed, the display of the mark 20a is changed on the display unit 20 that moves from the near point to the far point. The display control unit 42 controls the display unit 20 so as to make it happen.

  Here, in the visual acuity recovery training for myopia, while focusing on the mark 20a displayed on the display unit 20 moving from the near point to the far point, focusing on the mark, It is important to activate the imaging adjustment function of the eye such as the pupil, vergence / divergence. However, there are cases where it is difficult to maintain the concentration that keeps watching the fixed mark 20a while reciprocating the display unit 20 a plurality of times. In particular, when the user is a child of elementary school level, it is difficult to maintain concentration during training.

  Thereby, since the mark 20a displayed on the display part 20 changes as the user moves from the near point to the far point which is effective for the visual acuity recovery training for myopia, the user is conscious of the changing mark 20a. Makes it easier to concentrate. Therefore, compared with the conventional training apparatus in which a certain mark is displayed, effective training can be performed by continuing to look at the mark 20a while maintaining concentration during training.

<Control of vision recovery training for hyperopia>
In the visual acuity recovery training device 10 of the present embodiment, when performing the visual acuity recovery training for hyperopia, as shown in FIG. 8, while controlling the display of the mark 20a on the display unit 20, as shown in FIG. Processing is performed according to the control flow.

Specifically, in step S11, first, the user presses a vision recovery training start button in order to perform vision recovery training for hyperopia.
In step S12, the display control unit 42 controls the display unit 20 to display the mark 20a read from the storage unit 43.

  In step S13, the moving direction control unit 45 and the position control unit 46 included in the drive control unit 44 move the display unit 20 to the vicinity of the far point that is the initial position of the vision recovery training for hyperopia. In addition, when the visual acuity recovery training start button is pressed, if the display unit 20 is in the vicinity of the far point, it is only necessary to wait as it is. Moreover, about the process of step S2 and step S3, you may be performed simultaneously in parallel.

  In step S14, as a cue to start training, for example, a whistle sound is output from the sound output unit 49 such as a speaker to start a vision recovery training for hyperopia, and a certain mark 20a (see FIG. 4) is displayed. The display unit 20 is moved from the far point toward the near point at a predetermined speed (return path). At this time, similarly to the above-described visual acuity recovery training for myopia, the display control unit 42 controls the size of the mark 20a displayed on the display unit 20 to change.

  In step S15, the display unit 20 stopped at the near point is moved from the near point to the far point (outward path). Similar to the above-described visual acuity recovery training for myopia, when the side has no training effect (here, the movement from the near point to the far point), the mark 20a may be displayed while being moved, You may move as a display.

  In step S16, it is confirmed whether or not the number of reciprocating movements of the display unit 20 has exceeded a predetermined threshold value (for example, 10 reciprocations for one set of training with 20 reciprocations). If the predetermined threshold value has not been exceeded, step S14 to step S15 are repeated. And when it exceeds a predetermined threshold value, it progresses to Step S17.

  In step S17, the display unit 20 displaying the mark 20a is controlled to change the display of the mark 20a when moving the display unit 20 from a far point toward a near point at a predetermined speed. Specifically, as shown in FIG. 8, the owl picture as the mark 20a gradually turns backward, and the display changes to look back again in the vicinity of the far point. As a result, even when a child or the like is a user, the training effect can be improved more than before by keeping watching the mark 20a in a concentrated state without getting tired of continuing to look at the mark 20a during training. Can do.

  Further, in step S17, as in step S14 described above, the size of the mark 20a is changed so that the mark 20a having a substantially constant size can be seen from the user during training according to the position of the display unit 20. Change (see FIG. 8).

  In step S18, the display unit 20 stopped at the near point is moved to the far point. Also in this case, in the visual acuity recovery training for hyperopia, the mark 20a may remain displayed or may not be displayed when the display unit 20 moves on the forward path side.

  In step S19, it is confirmed whether or not the display unit 20 has reciprocated a predetermined number of times (for example, 20 times in the case of one set of 20 reciprocations). Here, when the predetermined number of times has not been reached, the steps S17 to S18 are repeated until the predetermined number of times is reached, and then the training is terminated.

  In the visual acuity recovery training device 10 of the present embodiment, as described above, when the visual acuity recovery training for hyperopia is performed, the display of the mark 20a is changed on the display unit 20 that moves from the far point toward the near point. The display control unit 42 controls the display unit 20 so as to make it happen.

  Here, in the vision recovery training for hyperopia, while focusing on the mark 20a displayed on the display unit 20 that moves from the far point toward the near point, focusing on the mark, It is important to activate the imaging adjustment function of the eye such as the pupil, vergence / divergence. However, there are cases where it is difficult to maintain the concentration that keeps watching the fixed mark 20a while reciprocating the display unit 20 a plurality of times. In particular, when the user is a child of elementary school level, it is difficult to maintain concentration during training.

  Thereby, since the mark 20a displayed on the display unit 20 changes when moving from a far point to a near point, which is effective for a vision recovery training for hyperopia, the user is aware of the changing mark 20a. Makes it easier to concentrate. Therefore, compared with the conventional training apparatus in which a certain mark is displayed, effective training can be performed by continuing to look at the mark 20a while maintaining concentration during training.

[Features of the visual acuity recovery training apparatus 10]
(1)
In the visual acuity recovery training device 10 of the present embodiment, the visual acuity recovery training is performed while moving the display unit 20 that displays the visual acuity recovery training mark 20a between the near point and the far point, and FIG. As shown in FIG. 8, the display unit 20 is controlled so that the display of the mark 20 a changes on the display unit 20 that moves between the far point and the near point.

  As a result, the user needs to continue to look at the mark 20a during training, but can be trained while maintaining concentration without getting bored by the change of the mark 20a. Therefore, compared with a conventional visual acuity recovery training apparatus that always displays a constant mark, training can be performed while maintaining the user's concentration during training, so that the training effect can be further improved. .

In particular, by carrying out training while changing animated images such as the above-mentioned changes in owl pictures, it is possible to effectively maintain concentration during training of users such as children who are difficult to maintain concentration. Can do.
As a result, regardless of the user's age or the like, the concentration effect during training can be maintained and the training effect can be improved.

(2)
In the visual acuity recovery training device 10 of the present embodiment, as shown in FIGS. 6 and 8, when the display unit 20 reciprocates between the near point and the far point, the same size is always displayed on the retina of the user. The display unit 20 is controlled to change the size of the mark 20a so that the mark 20a is displayed.

  As a result, since the user can always see the mark 20a of almost the same size during training, the information that enters the brain is reduced, and effective training is performed in a state in which the focus on the mark 20a is easily achieved. be able to.

In addition, since the mark 20a having almost the same size is always displayed from the user, it becomes difficult for the user to grasp the sense of distance from the mark 20a during the training, and the consciousness can be concentrated on the mark 20a. There is a risk of getting bored with the unchanged mark 20a.
Therefore, by combining with the control for changing the mark 20a during the movement described above, it is possible to carry out more effective visual acuity recovery training in a state where the mark 20a is concentrated.

(3)
In the visual acuity recovery training device 10 of the present embodiment, as shown in FIGS. 6 and 8, the mark 20a changes like a moving image according to the position between the far point and the near point.

  This makes it easier for the user to concentrate his / her consciousness on the mark 20a and to feel a sense of distance from the mark 20a due to a change in image display. Therefore, during training, the user can further improve the training effect by performing training while feeling a sense of distance from the mark 20a.

(4)
In the visual acuity recovery training device 10 of the present embodiment, a moving image in which the direction of the owl changes is displayed as an image for visual acuity recovery training that is changed during movement, as shown in FIGS.
As a result, the posture (orientation) of the owl as the mark 20a changes, so that the concentration during training can be easily maintained.

(5)
In the visual acuity recovery training device 10 of the present embodiment, as shown in FIGS. 5 and 7, the display of the mark 20 a described above is changed during movement after the number of reciprocating movements of the display unit 20 exceeds a predetermined threshold. Control is performed.

  Thereby, training is started by starting the control to change the mark 20a from the middle of the training in which the concentration power tends to be cut off while displaying the constant mark 20a (see FIG. 4) at the beginning of the training in which the concentration power is easily maintained. Effective training can be carried out while maintaining concentration until the second half of. As a result, the user's concentration during training can be more effectively maintained by starting the control for changing the display of the mark 20a at an appropriate timing during training.

(6)
In the visual acuity recovery training device 10 of the present embodiment, as shown in FIGS. 6 and 8, the mark 20a to be changed during movement is changed stepwise.

  Thereby, the user who has been tired of continuing to watch the mark 20a during training can concentrate his / her consciousness again on the mark 20a that changes in several stages. As a result, the user's consciousness can be more effectively concentrated on the mark 20a as compared with a simple one-time change.

(7)
In the visual acuity recovery training device 10 of the present embodiment, as shown in FIGS. 2 and 3, audio information is output from the audio output unit 49 such as a speaker in accordance with a change in the mark 20 a displayed on the display unit 20. .

Specifically, for example, in the visual acuity recovery training for myopia, when the far point shown in FIG. 6 is reached, a voice uttering “hoo” is output at the timing when the owl looks back here.
Thus, the user can obtain the voice information along with the change of the mark 20a, and can maintain his / her concentration without getting tired even if he / she continues to watch the mark 20a during training.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

(A)
In the above embodiment, an example in which the present invention is applied to the vision recovery training device 10 has been described. However, the present invention is not limited to this.

  For example, a three-dimensional image or the like is displayed on a liquid crystal screen of a PC (Personal Computer) to visually move the image between a far point and a near point, and the control flow described above (see FIGS. 5 and 7). The present invention may be implemented as a visual acuity recovery training control program that causes a computer to execute the visual acuity recovery training control method executed in accordance with (1).

  Even with this vision recovery training control program, by focusing and relaxing repeatedly during training, the imaging adjustment function of the eyes such as ciliary muscles and pupils is effectively operated, and the effects of vision recovery training are further improved. The effect similar to the effect acquired by the said vision recovery training apparatus 10 that it can improve can be acquired.

(B)
In the said embodiment, the display part 20 installed in the housing | casing part 11 was moved to the front-back direction, and it demonstrated and demonstrated as an example the structure where a user looks closely at the mark 20a for visual acuity recovery training. However, the present invention is not limited to this.

  For example, as shown in FIG. 9, by disposing a display unit 120 that displays a mark for vision recovery training in the housing unit 111 and moving the reflecting unit 150 such as a plane mirror in the front-rear direction, A reflective vision recovery training device 110 that visually moves a mark between near points can also be used.

  In such a reflection-type visual acuity recovery training apparatus 110, the control unit 140 moves the support unit 151 that supports the reflection unit 150 and the pedestal unit 152 on the floor surface 114 by the moving unit 113, and reflects the reflection on the display unit 120. The distance of the part 150 is changed. The moving unit 113 includes a motor 130, a pulley 131, and a belt 132. An eyepiece 112 and an illumination unit 116 are attached to the housing unit 111.

  As a result, the user gazes at the mark indirectly through the reflecting portion 150, and therefore the distance from the user's eye (eyepiece 112) to the mark in the casing 111 can be shortened. it can. Therefore, as compared with the visual acuity recovery training device 10 of the above embodiment, the size of the device in the movement direction of the mark can be reduced, and a more compact device can be configured.

(C)
In the above-described embodiment, an example using the owl (animal) picture mark (image for eyesight recovery training) 20a as the image for eyesight recovery training (target) has been described. However, the present invention is not limited to this.

  For example, as shown in FIG. 10, depending on the position of the display unit 20, a mark (such as a moving image such as an egg, a cracked egg, a cracked egg, or a chick comes out of the egg) Display control may be performed so as to display the image for vision recovery training 120a and the background 120b. At this time, when the display unit 20 moves to a far point, the audio output unit 49 may be controlled so that the chick that comes out of the egg rings “piyo”.

  Even in this case, since the child user, etc. can be trained in a state where concentration is maintained without getting tired of continuing to see the mark 120a during training, the training effect can be improved more than before. The same effect as described above can be obtained.

  Furthermore, it is not limited to “chicks” coming out of eggs, but as shown in FIGS. 14 (a) to 14 (d), “snakes”, “penguins”, “dinosaurs”, “stars” Or the like.

  In this case, what is necessary is just to control so that an audio | voice and a sound effect may be output from an audio | voice output part corresponding to what comes out of an egg. Moreover, the order which comes out of an egg is not decided, for example, by being controlled at random, a trainer can maintain concentration power still more.

(D)
In the above-described embodiment, the example has been described in which the mark 20a for visual acuity recovery training is continuously changed like moving image display throughout the movement of the display unit 20. However, the present invention is not limited to this.

  For example, as shown in FIG. 11, when the display unit 20 moves from a near point to a far point in a visual acuity recovery training for myopia, the owl looks back here for the first time when it passes a predetermined position near the far point. Such display control may be performed.

  Here, for example, at the beginning of training in the visual acuity recovery training for myopia, although the user is relatively easy to maintain the concentration, the concentration tends to be interrupted if the display unit 20 moves near the far point. There is.

  Therefore, by performing display control that changes the display of the mark 20a for the first time when moving to the vicinity of the far point, the user's concentration during training is maintained and the training effect is achieved by the minimum necessary image change. Can be improved.

  Moreover, it is preferable that the user during training always performs training while feeling a sense of distance from the mark 20a. For this reason, the position of the mark can be easily recognized by the change in the owl.

(E)
In the above-described embodiment, an example using the owl (animal) picture mark (image for eyesight recovery training) 20a as the image for eyesight recovery training (target) has been described. However, the present invention is not limited to this.

  For example, as shown in FIG. 12A, characters such as alphabets (for example, “G”), graphics, and the like may be displayed as marks (images for vision recovery training) 120c. Alternatively, as shown in FIG. 12B, a simple circular figure may be displayed as a mark (image for vision recovery training) 120d.

Here, for example, when an alphabet is used as an image for visual acuity recovery training, for example, as shown in FIG. 13, marks 220a in the background 220b are moved to “A”, “P”, “P” as shown in FIG. , “L”, “E”, and the display control may be performed so that one word is displayed. Further, in accordance with such display control, pronunciation such as English words may be output from the sound output unit 49 (see FIGS. 2 and 3) such as a speaker. In this case, the user can memorize one word together with voice information by concentrating and continuing to look at the alphabet.
In addition, it is desirable that the type of the mark can be appropriately selected according to the age and preference of the user who performs the vision recovery training.

(F)
In the above embodiment, an example in which the control for changing the image for eyesight recovery training (mark 20a) is performed when the number of times the display unit 20 reciprocates between the far point and the near point becomes a predetermined number or more. And explained. However, the present invention is not limited to this.
For example, the control may be such that the image for vision recovery training is changed each time the display unit 20 moves regardless of the number of reciprocating movements.

(G)
In the above-described embodiment, the display size of the mark 20a is determined according to the position of the display unit 20 that reciprocates between the far point and the near point so that the mark 20a having the same size can always be seen from the training user. An example of changing is described. However, the present invention is not limited to this.

For example, the visual acuity recovery training may be performed while always displaying an image of the same size regardless of the position of the display unit (the visual recovery training image).
However, since display control is performed so that the image of the same size is always visible to the user, the user can easily concentrate on the image in which the size of the image is not changed. More preferably, the control is combined.

(H)
In the above embodiment, the vision recovery training device 10 capable of performing both myopia vision recovery training and hyperopia vision recovery training has been described as an example. However, the present invention is not limited to this.
For example, it may be a visual acuity recovery training apparatus capable of performing only one of a visual acuity recovery training for myopia or a visual acuity recovery training for hyperopia.

(I)
In the said embodiment, the example using a liquid crystal display panel was given and demonstrated as the display part 20 which displays the image for visual acuity recovery training. However, the present invention is not limited to this.
For example, in addition to the liquid crystal display panel, other electronic display means such as an organic EL (Electro-Luminescence) panel or a CRT (Cathode Ray Tube) can be used.

(J)
In the above embodiment, the vision recovery training device 10 in which the display unit 20 and the like are stored in the housing unit 11 has been described as an example. However, the present invention is not limited to this.

  For example, if a user can feel a sense of distance by displaying a three-dimensional image or the like on a display screen of a PC or a mobile phone, it is possible to carry out vision recovery training while viewing the display screen. .

  The visual acuity recovery training device of the present invention has an effect that, regardless of the user, the concentration during the training can be maintained as long as possible and a sufficient effect can be obtained by the visual acuity recovery training. Widely applicable to devices.
