Description

  The present invention relates to a vision improvement training device and a vision improvement training control program for improving the visual acuity that has decreased due to myopia or presbyopia due to the training of the imaging adjustment function of the eye.

  In recent years, a vision improvement training apparatus has been used in order to improve the visual acuity that has deteriorated due to a reduction in the imaging adjustment function of the eye due to adjustment tension or weakness of the eye adjustment muscle (ciliary muscle).

  In such a vision improvement training device, it is particularly important that the trainer concentrates his / her consciousness only on the vision improvement training image to enhance the training effect.

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

As a result, the size of the target figure changes in proportion to the optical 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. be able to.
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 improvement training apparatus has the following problems.

  That is, in the vision improvement 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 trainee during the movement of the target, If the movement of the target is stopped for a predetermined time in order to promote the concentration of the trainee at the far point, the stimulus of the target change may be lost and the trainee may be distracted. In this case, the concentration of the trainee is easily interrupted, which may reduce the training effect.

  An object of the present invention is to provide a vision improvement training apparatus and a vision improvement training capable of performing more effective training without interrupting the concentration of the trainee even when the target is stopped near the far point / near point. It is to provide a control program.

  A vision improvement training device according to a first invention is a vision improvement training device for training 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 improvement training. The moving unit reciprocates the image displayed on the display unit between the far point and the near point. When the image moves back and forth between the far point and the near point, the control unit changes the size of the image stopped at the far point or the near point after moving to the forward or return way side where the training effect is effective. To control the display.

  Here, for example, by displaying a predetermined vision improvement training image on a display unit installed inside the housing or the like, the trainer can look away inside the housing while moving the image away or closer. In the vision improvement training apparatus that performs eye imaging adjustment training, when moving on the side having the training effect, control is performed so that the image size is changed after the movement of the image in the forward or return path is stopped.

  Here, the movement on the side having the training effect means, for example, movement from the near point to the far point when the trainee is myopic. On the other hand, when the trainee is hyperopic (presbyopia), it means movement from a far point to a near point.

  The image for training in vision improvement includes figures such as circles, triangles, squares, 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 eye lens for adjusting the thickness by the relaxation and contraction of the ciliary muscle (annular muscle) is not performed at all. The external point that forms an image in the fovea of the retina in the state, or the point where the image (display unit) is farthest from the trainee in the vision improvement training apparatus. On the other hand, the near point, which is the closest point in the range in which the image reciprocates, is an external point imaged in the fovea of the retina with the lens lens thickness adjustment being maximized, or a vision improvement training device The point where the image (display unit) is closest to the trainee. The near point and the far point are one point at a predetermined position where the optical distance between the trainee and the image (display unit) is short, and one point at a predetermined position where the optical distance is longer than the one point. , Each may be set.

  Further, as a moving unit that reciprocates the image displayed on the display unit between the far point and the near point, for example, the conveying unit including a pulley, a belt, or the like, or a screw is rotated to move the display unit in a desired direction. It includes transport means for reciprocating movement, or display means for performing display by image expression so that the image is reciprocally moved between a far point and a near point visually.

  The forward path refers to the movement path on the side moving from the near point to the far point, and the return path refers to the movement path when moving from the far point to the near point. Specifically, for example, when the trainee is myopic, when moving from the near point to the far point, the image is watched to perform myopia vision improvement training, and the image reaches the far point and stops. Then, control is performed to reduce the display size of the image. On the other hand, when the trainee is farsighted, when moving from a far point to a near point, he / she gazes at the image and conducts vision improvement training for hyperopia, and when the image reaches the near point and stops, the image is displayed. Control to reduce the size.

  Thereby, after the image is moved to the side effective for the vision improvement training, by changing the display size of the image, the trainee can continue to view the image while focusing on the image. As a result, since the concentration of the trainee during training can be maintained without interruption, the training effect can be improved as compared with the conventional technique.

  The vision improvement training device according to the second invention is the vision improvement training device according to the first invention, wherein the control unit moves the trainee when the image reciprocates between the far point and the near point. Enlargement / reduction display is performed according to the position of the image so that an image of the same size is always displayed on the retina.

  Here, in the visual acuity improvement training for myopia or hyperopia, the image is displayed near the far point and smaller as the near point is approached so that an image of the same size is always displayed on the retina of the trainee.

  Here, when display control is performed so that an image of the same size is always visible from the trainee in this way, the trainee has less stimulation due to changes in the image that moves during training, and in particular, concentration is interrupted. It becomes easy.

  As a result, when such enlargement / reduction control is performed, the trainee always sees an image of the same size, and thus may not be able to recognize that he / she has stopped moving to a far or near point. There is. Therefore, by the above-described reduction / enlargement display control at the far point or near point, the trainer can easily recognize that the movement in the forward / return path has stopped, and the training effect can be enhanced by maintaining the concentration.

  In addition, since images of the same size are always displayed on the retina of the trainee, when the image is reciprocated between the far point and the near point, the trainer can easily focus on the image. The consciousness can be concentrated on an image that reciprocates between a far point and a near point. As a result, more effective visual improvement training can be performed.

  The vision improvement training device according to the third invention is the vision improvement training device according to the second invention, wherein the control unit displays the image at the near point when the stop is stopped at the far point or the near point, Alternatively, the display unit is controlled to reduce or enlarge the display size at the far point.

  Here, in a vision improvement training apparatus that displays an image that is large near the far point and smaller as it approaches the near point so that an image of the same size is always displayed on the retina of the trainee, the near point size is displayed at the far point. The near point is reduced / enlarged until the far point size is reached.

  Specifically, for example, in a visual acuity improvement training for myopia, an image stopped at a far point is reduced and displayed to a display size at the near point. On the other hand, in the vision improvement training for hyperopia, the image stopped at the near point is enlarged and displayed up to the display size at the far point.

  Thereby, in the visual acuity improvement training for myopia / hyperopia, the concentration of the trainer can be maintained for a predetermined time after the movement to the side having the training effect. Then, by setting the degree of reduction / enlargement based on the display size at the far point / near point, it is possible to adjust the image size or the focus on which the trainer cannot continue to adjust the eye to focus on the image. Therefore, it is possible to avoid an image size that would praise the user and to carry out an effective visual improvement training.

  A vision improvement training device according to a fourth invention is the vision improvement training device according to any one of the first to third inventions, and the control unit stops when the image moves from a near point to a far point. After that, the display unit is controlled to reduce the size of the image.

  Thus, the trainer can concentrate so as to focus on the image when moving from a near point to a far point having a training effect. And even when the image stops at a far point, the trainer will continue to improve visual acuity without losing concentration because the image will become smaller and blur will occur in focus. Training can be done. As a result, the effect of the visual acuity improvement training for myopia can be improved as compared with the prior art.

  A vision improvement training apparatus according to a fifth invention is the vision improvement training apparatus according to any one of the first to fourth inventions, wherein the control unit stops when the image moves from a far point to a near point. After that, the display unit is controlled to reduce the size of the image.

  Here, in the so-called hyperopia visual acuity improvement training that aims to improve visual acuity by gazing at an image (target) moving from a far point to a near point, it stopped after moving from a far point to a near point with training effect Control is performed so that the size of the image is reduced to, for example, half the display size at the near point.

  Thus, the trainer can concentrate so as to focus on the image when moving from a far point to a near point having a training effect. And even when the image stops at a near point, the trainer will continue to improve visual acuity without losing concentration because the image will become smaller and blur will occur in focus. Training can be done. As a result, the effect of the vision improvement training for hyperopia can be improved as compared with the conventional case.

  A vision improvement training apparatus according to a sixth invention is the vision improvement training apparatus according to any one of the first to fifth inventions, wherein the control unit stops when the image moves from a near point to a far point. After that, the display unit is controlled to enlarge the size of the image.

  Here, in the so-called myopia vision improvement training, which is aimed at improving the visual acuity by gazing at the image (target) moving from the near point to the far point, it stopped after moving from the near point to the far point with the training effect Control is performed so that the size of the image is enlarged to, for example, double the display size at the far point.

  Thus, the trainer can concentrate so as to focus on the image when moving from a near point to a far point having a training effect. And even when the image stops at a far point, the trainer increases the size of the image, so the image becomes clear when focused on the image, and the training effect is lost without losing sight of the image. And can continue to improve visual acuity without interrupting concentration. As a result, the effect of the visual acuity improvement training for myopia can be improved as compared with the prior art.

  A vision improvement training apparatus according to a seventh invention is the vision improvement training apparatus according to any one of the first to sixth inventions, wherein the control unit stops when the image moves from a far point to a near point. After that, the display unit is controlled to enlarge the size of the image.

  Here, in the so-called hyperopic visual acuity improvement training that aims to improve visual acuity by gazing at an image (target) moving from a far point to a near point, it stopped after moving from a far point to a near point with training effect Control is performed so that the size of the image is enlarged to, for example, a display size at a far point.

  Thus, the trainer can concentrate so as to focus on the image when moving from a far point to a near point having a training effect. Even when the image stops at a near point, the trainer increases the size of the image, so that the image becomes clear when focused on the image, and the user can concentrate without losing sight of the image. Visual improvement training can be continued without interruption. As a result, the effect of the vision improvement training for hyperopia can be improved as compared with the conventional case.

  An eyesight improvement training device according to an eighth invention is the eyesight improvement training device according to any one of the first to seventh inventions, and the control unit stops when the image moves to a side having a training effect. Then, after a predetermined time has elapsed, the control unit is controlled to change the size of the image.

  Here, for example, in the visual acuity improvement training for myopia, control is performed so that the size of the image that has stopped after moving from the near point to the far point is changed after a predetermined time (for example, 0.25 to 3 seconds) has elapsed. .

  Thereby, after the image moved to the side having the training effect stops, the trainee can obtain time to focus on the image. Therefore, the trainee can focus further on the image whose size changes after firmly focusing on the image stopped at the far point or near point. As a result, the trainer can more effectively concentrate on the image and focus while focusing on the image.

  A vision improvement training apparatus according to a ninth aspect is the vision improvement training apparatus according to any one of the first to eighth aspects, wherein the control unit is predetermined when changing the size of the image. The display unit is controlled to gradually change the size over time.

  Here, for example, in the visual acuity improvement training for myopia, the size of the image that has stopped after moving from the near point to the far point is gradually changed over a predetermined time (for example, 0.25 to 1 second). Control.

  This eliminates the difficulty of focusing on the image due to a sudden change in the size of the image, and the trainee can easily focus on the image whose size changes. As a result, more effective visual improvement training can be performed.

  A vision improvement training apparatus according to a tenth invention is the vision improvement training apparatus according to any one of the fourth to seventh inventions, wherein the control unit is from a far point to a near point or from a near point. After moving to a point and changing the size of the stopped image, after moving still for a predetermined time, the movement in the reverse direction is started.

  Here, for example, in the visual acuity improvement training for myopia, after reducing or enlarging the image that has stopped moving from the near point to the far point, it is left stationary for a predetermined time (for example, 0.25 to 3 seconds) Thereafter, control is performed so as to start movement in the reverse direction.

  Thus, the trainee stops the image that has moved to the side having the training effect and focuses on the image whose size changes, and then remains stationary in that state for a predetermined time, so that it is easier to maintain the concentration. As a result, the trainer can more effectively concentrate on the image and focus on the image while performing the vision improvement training.

  A vision improvement training control program according to an eleventh aspect of the invention is a vision improvement training control program for training an eye imaging adjustment function, comprising: a display step, a movement step, and a control step. The computer executes the control method. In the display step, an image for visual improvement training is displayed. In the moving step, the displayed image is reciprocated between the far point and the near point. In the control step, when the image moves back and forth between the far point and the near point, the size of the image stopped at the far point or near point after moving to the forward or return path side where the training effect is effective is changed. To control.

  Here, for example, while the image for a predetermined visual acuity improvement training is displayed on a liquid crystal display device or the like, the image formation adjustment training is performed by moving the image away or close while the trainee is gazing at the image. In the control program of the vision improvement training apparatus, control is performed so as to change the size of the stopped image after movement on the side having the training effect.

  Here, the movement on the side having the training effect means, for example, movement from the near point to the far point when the trainee is myopic. On the other hand, when the trainee is farsighted, it means movement from a far point to a near point.

  The image for training in vision improvement includes figures such as circles, triangles, squares, and ring shapes, alphabets, hiragana, katakana, photographs, animations, and the like. As means for displaying such an image, electronic display means such as a liquid crystal display, an organic EL display, and 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 eye lens for adjusting the thickness by the relaxation and contraction of the ciliary muscle (annular muscle) is not performed at all. The external point that forms an image in the fovea of the retina in the state, or the point where the image (display unit) is farthest from the trainee in the vision improvement training apparatus. On the other hand, the near point, which is the closest point in the range in which the image reciprocates, is an external point imaged in the fovea of the retina with the lens lens thickness adjustment being maximized, or a vision improvement training device The point where the image (display unit) is closest to the trainee. The near point and the far point are one point at a predetermined position where the optical distance between the trainee and the image (display unit) is short, and one point at a predetermined position where the optical distance is longer than the one point. , Each may be set.

  Further, as a means for reciprocating the displayed image between the far point and the near point, for example, a conveying means including a pulley, a belt, or the like, or a conveyance for rotating the display means in a desired direction by rotating a screw. Means, or display means for performing display by image expression so that the image is reciprocally moved between the far point and the near point visually.

  The forward path refers to the movement path on the side moving from the near point to the far point, and the return path refers to the movement path when moving from the far point to the near point. Specifically, for example, when the trainee is myopic, when moving from the near point to the far point, the image is watched to perform myopia vision improvement training, and the image reaches the far point and stops. Then, control is performed to reduce the display size of the image. Or, conversely, when the image reaches the far point and stops, control is performed to enlarge the display size of the image. On the other hand, when the trainee is farsighted, when moving from a far point to a near point, he / she gazes at the image and conducts vision improvement training for hyperopia, and when the image reaches the near point and stops, the image is displayed. Control to reduce the size. Or, conversely, when the image reaches the near point and stops, control is performed to enlarge the display size of the image.

  Thereby, after the image is moved to the side effective for the vision improvement training, by changing the display size of the image, the trainee can continue to view the image while focusing on the image. As a result, since the concentration of the trainee during training can be maintained without interruption, the training effect can be improved as compared with the conventional technique.

  According to the visual acuity improvement training device according to the present invention, it is possible to maintain the concentration of the trainee during training without interruption, and to improve the training effect as compared with the conventional art.

  The vision improvement training apparatus 10 according to an embodiment of the present invention will be described below with reference to FIGS.

[Configuration of overall vision improvement training apparatus 10]
As shown in FIGS. 1 and 2, the vision improvement training device 10 according to the present embodiment is a mark (image for vision improvement training) displayed on the display unit 20 in the housing unit 11 that reciprocates in a predetermined direction. ) This is an apparatus for improving 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 trainer, 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 trainee observes the moving mark 20a and performs training.

  This 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, or the image (display unit) is trained in the vision improvement training device. This is the point farthest away from the person. On the other hand, the near point is an external point imaged in the fovea of the retina when the lens thickness is extremely adjusted, or the image (display unit) is closest to the trainee in the vision improvement training apparatus. A point that becomes a position. The near point and the far point are one point at a predetermined position where the optical distance between the trainee and the image (display unit) is short, and one point at a predetermined position where the optical distance is longer than the one point. , Each may be set.

  Further, in this embodiment, as the eyesight improvement training mark 20a, as shown in FIG. 4 and the like, a substantially circular ring-shaped figure is used, but it is easy for the trainee to focus on the training. Any shape or color is acceptable.

  As shown in FIGS. 1 and 2, the vision improvement 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, 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 trainee who performs vision improvement training focuses on the eye. . 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 eyesight improvement 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 illuminating unit 16 is an illuminating device installed on the wall surface on the side where the eyepiece unit 12 is provided so that the trainee 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 trainee 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.

  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, and a speed control unit 47. ing.

  The input unit 31 is an input switch or the like, and control information related to the mark 20a (image for improving visual acuity training (graphic)) displayed on the display unit 20 and position information related to a near point and a far point to be described later improve 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 an optical distance from the eyepiece part 12 to the display part 20, since there are individual differences by the trainee, it is necessary to adjust for each trainer. Specifically, the near point is in the range of 100 to 500 mm from the eyepiece 12, and the far point is in the range of 500 mm or more from the eyepiece 12, and appropriate numerical values are input for each trainer. In addition, the range of a near point and a far point is not limited to the above, What is necessary is just to adjust and use a range for every trainer.

  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 and the like are transmitted.

  The display control unit 42 controls the display unit 20 to display the mark 20a having an appropriate size based on the control information received from the input control unit 41, the position information of the display unit 20, and the like. In addition, the display control unit 42 controls the display unit 20 to display information on the optical 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. In this way, by displaying information such as the optical 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 visual acuity improvement training, which graphic is to what optical distance The trainer can be made aware of whether it has become visible. Therefore, it is possible to make the trainee recognize the effect of the vision improvement training and to motivate the next vision improvement training.

  In addition, the display control unit 42 controls the display unit 20 to change the size of the graphic displayed on the display unit 20 in proportion to the optical distance between the eyepiece unit 12 and the display unit 20. Specifically, as shown in FIGS. 6A to 6C, the display control unit 42 displays the mark 20a small near the near point, and the display unit 20 moves from the middle point to the far point. The display unit 20 is controlled so that the mark 20a is gradually displayed larger as the distance from the eyepiece unit 12 increases. Conversely, when the display unit 20 is moved from the far point to the near point, as shown in FIGS. 8A to 8C, the display control unit 42 displays a large mark 20a near the far point. Then, the display unit 20 is controlled so that the mark 20a is displayed smaller as the near point is approached. As a result, a mark 20a having almost the same size is always displayed on the retina of the trainee performing the vision improvement training regardless of the optical 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 trainee can easily focus the eye on the mark 20a. For this reason, the trainee who performs visual acuity improvement training becomes easy to see the mark 20a, and can implement visual acuity improvement training in the state 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 trainee 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 vision improvement training, the effect of the vision improvement 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.

  The color setting of the mark 20a and the background 20b is not particularly limited, but the display control unit 42 selects one of red, green, or blue as the color of the mark 20a and black as the color of the background 20b. Is selected, the trainer 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. In addition, by making the background 20b black, it is possible to further easily identify the mark 20a and to make it easier for a trainer who performs a vision improvement training to concentrate on the mark 20a. Furthermore, when the background color is set to black, the trainee can perform training in a more relaxed state because the eye is least stimulated.

  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 optical distances of near points and far points set for each trainer performing the vision improvement training, and the trainer sets the near point previously set when starting the vision improvement training. Information regarding the optical distances of the point and 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 improvement 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. It should be noted that the initial position of the display unit 20 at the start of training varies depending on whether the visual acuity improvement training for myopia or the visual acuity improvement 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 improvement training. For example, when the visual acuity improvement 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 optical distance from the eyepiece unit 12 to the display unit 20 based on, for example, the number of revolutions of the motor 30. The optical 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. In the case where the moving speed is changed stepwise, for example, a trainer or doctor from any moving speed of 10 mm / sec, 40 mm / sec, 80 mm / sec, 160 mm / sec, 250 mm / sec, 500 mm / sec, etc. The operator can select the most suitable moving speed. In addition, when the moving speed is continuously changed, a trainer or an operator can make a fine adjustment of the optimal moving speed. Such a moving speed of the display unit 20 may be input directly from the input unit 31 by a trainee or an operator.

  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 in the front-rear direction when the display unit 20 is moved, the trainer displays the mark displayed on the display unit 20. This makes it easier to focus the eyes on 20a and to determine whether or not the eyes are in focus.

  Here, in the vision improvement training device 10, since it is necessary to secure an optical 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. To do. Therefore, by providing an optical device such as a convex lens or a mirror between the optical paths from the eyepiece unit 12 to the display unit 20, the depth can be reduced and the device can be downsized.

<Outline of vision improvement training>
The trainee sees 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 trainee concentrates on the mark 20a so as to make it clearly visible, and focuses the eyes. In this way, the trainer repeatedly reciprocates between the near point and the far point with the eye focused on the mark 20a, so that the ciliary muscles and pupils of the trainee's eyes during training, 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

  Note that the movement of the mark 20a between the near point and the far point described above is preferably performed, for example, 10 round trips as 1 set, and 2 to 3 sets once 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 improved.

<Control of vision improvement training for myopia>
In the visual acuity improvement training device 10 of the present embodiment, when performing visual acuity improvement training for myopia, according to the control flow as shown in FIG. 5, as shown in FIGS. 6 (a) to 6 (d), The display of the mark 20a on the display unit 20 is controlled.

  Specifically, in step S1, first, a trainee or an operator presses a vision improvement training start button in order to perform a vision improvement 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 S3, the display unit 20 is moved to the vicinity of the near point which is the initial position of the visual acuity improvement training for myopia by the movement direction control unit 45 and the position control unit 46 included in the drive control unit 44. In addition, what is necessary is just to wait as it is, when the display part 20 exists in the vicinity of a near point when the vision improvement training start button is pressed. 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 made to make the trainer recognize the start of the vision improvement training, and the display unit 20 displaying the mark 20a is moved from the near point to the far point. To move at a predetermined speed (outward). 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, as shown in FIG. 6A to FIG. 6C, from the trainer who is training, depending on the position of the display unit 20, that is, the optical distance from the eyepiece unit 12 to the display unit 20. The size of the mark 20a is changed so that the mark 20a having a substantially constant size can be seen.

  Here, regarding the size of the mark 20a that changes according to the position of the display unit 20, the size displayed at the far point is displayed as the far point size s2 (see FIG. 9A), and is displayed at the near point. The reduced size is indicated as a near point size s1 (see FIG. 9A).

  In step S5, it is confirmed whether or not a predetermined time (for example, 0.25 to 3 seconds) has elapsed since the display unit 20 stopped at the far point. And when predetermined time passes, it will transfer to step S6. The predetermined time can be set and input in advance before starting the training.

  In step S6, the size of the mark 20a displayed on the display unit 20 stopped at the far point is gradually changed to the near point size as shown in FIG. 6 (d). Specifically, as shown in FIG. 9A, the size of the mark 20a is enlarged from the near point size s1 to the far point size s2 during the period (t1-t0) in which the point moves from the near point to the far point. . Then, after the display unit 20 moves to the far point and stops for a predetermined time (t2-t1), the mark 20a is gradually reduced to the near point size s1 over a predetermined time (t3-t2).

  In step S7, it is confirmed whether or not a predetermined time (for example, 0.25 to 3 seconds at t4-t3) has elapsed since the mark 20a displayed on the display unit 20 has been reduced to the near point size s1. And when predetermined time (t4-t3) passes, it will transfer to step S8. The predetermined time can be set and input in advance before starting the training.

  In step S8, the display unit 20 is moved from the far point to the near point while the mark 20a reduced to the near point size s1 is returned to the far point size s2 and displayed.

  In step S9, it is confirmed whether or not the display unit 20 has reciprocated a predetermined number of times (for example, 10 times). Specifically, when the number of reciprocating movements does not reach a predetermined number, on the forward path, the display unit 20 stopped at the near point is moved toward the far point. Then, on the return path, the display unit 20 stopped at the far point is moved toward the near point. Such reciprocation of the display unit 20 (steps S4 to S8) is repeated until a predetermined number of times is reached, and then the training is terminated.

  As described above, in the visual acuity improvement training device 10 of the present embodiment, when the visual acuity improvement training for myopia is performed, the display of the mark 20a is displayed on the display unit 20 that has moved from the near point to the far point and stopped. The size is controlled to be reduced from the enlarged far point size to the near point size.

  Here, in the visual acuity improvement training for myopia, while focusing on the mark 20a displayed on the display unit 20 moving from the near point to the far point, the ciliary muscles, pupils, and vergence of the trainee's eyes. -It is important to operate the eye image adjustment function such as diverging. In particular, it is important to maintain concentration while focusing on the mark 20a displayed on the display unit 20 that has reached the far point. However, if the display unit 20 that has moved to the far point stops, the trainee may stop watching the mark 20a and the training effect may be reduced.

  As a result, the trainer focuses on the mark 20a when moving from the near point to the far point, which is effective for the visual acuity improvement training for myopia. When the distance reaches the far point, the size of the mark 20a changes when a predetermined time elapses, so that the trainer can continue to concentrate on the mark 20a, and the size of the mark 20a changes. You can try to focus. As a result, after the movement of the display unit 20 from the near point to the far point is stopped, the concentration of the trainer is prevented from being interrupted for a predetermined time as compared with the conventional case, and the visual improvement training is performed more effectively than the conventional method. it can.

  In particular, in the apparatus in which the size of the mark 20a reflected on the retina of the trainee during training is constantly controlled regardless of the position of the display unit 20 as in the present embodiment, the stimulus received by the trainee is There will be fewer states. Therefore, it is difficult to continue to see the mark 20a stopped after moving to the far point, but the trainer's concentration is continued by the size change of the mark 20a after the far point stop, which is effective. Visual improvement training for myopia can be implemented.

  Although the case where the size of the mark 20a is reduced at the far point has been described here, for example, as shown in FIG. 9B, the size of the mark 20a is increased to the enlarged size s3 at the far point. The same effect can be obtained. Specifically, the enlarged size s3 is, for example, twice the far point size s2.

  Further, the range of the size change of the mark 20a after stopping at the far point is not limited to the respective sizes of the near point size s1 and the enlarged size s3, and may be adjusted and used for each trainer. .

<Control of vision improvement training for hyperopia>
In the visual acuity improvement training device 10 of the present embodiment, when performing the visual acuity improvement training for hyperopia, according to the control flow as shown in FIG. 7, as shown in FIGS. 8A to 8D, The display of the mark 20a on the display unit 20 is controlled.

  Specifically, in step S11, first, a trainee or an operator presses a vision improvement training start button in order to perform a vision improvement 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 improvement training for hyperopia. Note that when the vision improvement training start button is pressed, if the display unit 20 is in the vicinity of the far point, the user may 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 the training, for example, a whistle sound is made to make the trainee recognize the start of the vision improvement training, and the display unit 20 displaying the mark 20a is moved from the far point to the near point. To move at a predetermined speed (return trip). At this time, similarly to the above-described visual acuity improvement training for myopia, the display control unit 42 controls the size of the mark 20a to change according to the position of the display unit 20.

  In step S15, it is confirmed whether or not a predetermined time (for example, 0.25 to 3 seconds) has elapsed since the display unit 20 stopped at the near point. And when predetermined time passes, it will transfer to step S16.

  In step S16, the size of the mark 20a displayed on the display unit 20 stopped at the near point is gradually changed to the reduced size s4 as shown in FIG. 8D. Specifically, as shown in FIG. 9C, the size of the mark 20a is reduced and displayed from the far point size s2 to the near point size s1 during the period (t1-t0) during which the far point moves to the near point. . Then, after the display unit 20 moves to the near point and stops for a predetermined time (t2-t1), the mark 20a is gradually reduced to the reduction size s4 over a predetermined time (t3-t2). The reduced size s4 is, for example, a size that is ½ of the near point size s1.

  In step S17, it is confirmed whether or not a predetermined time (from t4 to t3, for example, 0.25 to 3 seconds) has elapsed since the mark 20a displayed on the display unit 20 has been enlarged to the far point size s2. . And when predetermined time passes, it will transfer to step S18.

  In step S18, the display unit 20 is moved from the near point to the far point while the mark 20a reduced to the reduced size s4 is displayed back to the near point size s1.

  In step S19, it is confirmed whether or not the display unit 20 has reciprocated a predetermined number of times (for example, 10 times). Specifically, when the number of reciprocating movements does not reach a predetermined number, on the forward path, the display unit 20 stopped at the near point is moved toward the far point. Then, on the return path, the display unit 20 stopped at the far point is moved toward the near point. Such reciprocation of the display unit 20 (steps S14 to S18) is repeated until a predetermined number of times is reached, and then the training is terminated.

  In the visual acuity improvement training device 10 of the present embodiment, as described above, when the visual acuity improvement training for hyperopia is performed, the display of the mark 20a is displayed on the display unit 20 that has moved from the far point to the near point and stopped. The size is controlled to be reduced from the near point size to half the near point size.

  Here, in the vision improvement training for hyperopia, while focusing on the mark 20a displayed on the display unit 20 moving from the far point toward the near point, the ciliary muscles, pupils, and convergence of the trainee's eyes. -It is important to operate the eye image adjustment function such as diverging. In particular, it is important to maintain concentration while focusing on the mark 20a displayed on the display unit 20 that has reached the near point. However, if the display unit 20 that has moved to the near point stops, the trainee stops watching the mark 20a and the training effect may be reduced.

  As a result, the trainer focuses on the mark 20a when moving from the far point to the near point, which is effective for the vision improvement training for hyperopia. When the near point is reached, the trainer can continue to concentrate on the mark 20a by changing the size of the mark 20a after a predetermined time has elapsed. You can try to focus. As a result, after the movement of the display unit 20 from the far point to the near point is stopped, the concentration of the trainer is prevented from being interrupted for a predetermined time as compared with the conventional case, and the visual acuity improvement training can be carried out more effectively than before. it can.

  In particular, as in the present embodiment, in an apparatus that is controlled so that the size of the mark 20a reflected on the trainee's retina during training is always constant regardless of the optical distance between the display unit 20 and the eyepiece unit 12. , The trainee is less stimulated. Therefore, although it was difficult to continue to see the mark 20a stopped after moving to the near point, the trainer's concentration is continued by the size change of the mark 20a after the near point stop, which is effective. Vision improvement training for hyperopia can be implemented.

  Although the case where the size of the mark 20a is reduced at the near point has been described here, for example, as shown in FIG. 9D, the size of the mark 20a is enlarged to the far point size s2 at the near point. However, the same effect as described above can be obtained.

  Further, the range of the size change of the mark 20a after stopping at the far point is not limited to the respective sizes of the near point size s1 and the enlarged size s3, and may be adjusted and used for each trainer. .

[Features of the visual acuity improvement training device 10]
(1)
The vision improvement training device 10 of the present embodiment moves the display unit 20 that displays the vision improvement training mark 20a between the near point and the far point, and the size of the mark 20a according to the position of the display unit 20. The visual acuity improvement training is performed so that the mark 20a having the same size is always displayed on the retina of the trainee by changing the height. And the visual acuity improvement training apparatus 10 has a training effect in the visual acuity improvement training of myopia or hyperopia, as shown in FIGS. 6 (a) to 6 (d) and FIGS. 8 (a) to 8 (d). Control is performed so that the size of the mark 20a is changed in a state where the display unit 20 is stopped at the far point or near point after the side movement.

  Thereby, for example, in the vision improvement training for myopia, even when the display unit 20 moves from the near point to the far point and stops at the far point, the trainee focuses on the moving mark 20a. After that, it is possible to keep focusing on the mark 20a whose size changes even in the stopped state without interrupting the concentration. Therefore, by focusing on the mark 20a whose size changes for a while after the display unit 20 stops at the far point, the training effect can be improved as compared with the conventional vision improvement training. it can.

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

  Here, when the display size of the mark 20a is changed according to the optical distance between the display unit 20 and the eyepiece unit 12 so that the mark 20a of the same size can be seen at all times as seen from the trainee in this way. Even if the display unit 20 stops, it is difficult for the trainee to recognize that the display unit 20 is at the end point of the forward path.

  As a result, the trainee can recognize that the display unit 20 has stopped by moving to the end point in the forward or return path by changing the display size of the mark 20a. Therefore, the state of focusing on the mark 20a at the end point can be maintained for a longer time than before, and the training effect can be further improved.

  In addition, since the trainer always sees the mark 20a of almost the same size during the 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 easy to focus. Can do.

(3)
In the visual acuity improvement training device 10 of the present embodiment, as shown in FIGS. 6D and 8D, the mark 20a displayed on the display unit 20 that has moved to a far point or a near point and stopped is displayed as a near point. The image is reduced and enlarged until the point size s1 or the far point size s2 is reached.

  Here, for example, when the mark 20a stopped at the far point is reduced to a size smaller than the near point size s1, the trainee may give up on focusing because the mark 20a is too small.

  Thus, by reducing and enlarging the mark 20a to an appropriate size, the trainee focuses on the size change of the mark 20a stopped after moving on the side having the training effect while maintaining the concentration. Can do. As a result, the effect of the visual acuity improvement training can be improved as compared with the conventional case.

(4)
In the visual acuity improvement training apparatus 10 according to the present embodiment, in the visual acuity improvement training for myopia, the display unit 20 moves from the near point to the far point as shown in FIGS. After stopping, the mark 20a is reduced and displayed from the far point size s2 to the near point size s1.

  Thereby, in the visual acuity improvement training for myopia, the training for focusing on the mark 20a which is reduced and blurred while maintaining the concentration is continued with respect to the mark 20a which has moved to a far point and stopped. Can do. Therefore, the effective process part of the visual acuity improvement training for myopia can be made longer by a predetermined time than before, and the effect of the visual acuity improvement training can be further improved.

(5)
In the visual acuity improvement training device 10 of the present embodiment, in the visual acuity improvement training for hyperopia, as shown in FIGS. 8A to 8D, the display unit 20 moves from the far point toward the near point. After the stop, the mark 20a is reduced and displayed from the near point size s1 to the reduced size s4.

  Thereby, in the vision improvement training for hyperopia, the training to focus on the mark 20a that is reduced and blurred while maintaining the concentration with respect to the mark 20a that has moved to the near point and stopped is continued. Can do. Therefore, the effective process part of the vision improvement training for hyperopia can be made longer by a predetermined time than before, and the effect of the vision improvement training can be further improved.

  Thereby, after the display unit 20 is stopped, the trainee changes the size of the mark 20a after a predetermined time has elapsed, so that the trainee can focus on the mark 20a whose size changes in a state where the concentration is increased. Vision improvement training can be continued in an attempt to match. As a result, the effect of the visual acuity improvement training can be improved as compared with the conventional case.

(7)
In the visual acuity improvement training apparatus 10 of the present embodiment, as shown in FIGS. 9A to 9D, in the visual acuity improvement training for myopia, after the display unit 20 stops at a far point, In the vision improvement training, after the display unit 20 stops at the near point, the size of the mark 20a is gradually changed over a predetermined time (t3-t2).

  As a result, the size of the mark 20a is abruptly changed, and as a result, the trainer avoids discontinuing concentration, and the mark 20a is secured while securing the time necessary for focusing. The size of the can be changed. As a result, the effect of the visual acuity improvement training can be improved as compared with the conventional case.

(8)
In the visual acuity improvement training apparatus 10 according to the present embodiment, the size of the mark 20a stopped after moving from the far point to the near point or from the near point to the far point is reduced or enlarged, and then displayed in FIG. As shown in FIG. 9 (d), the movement in the reverse direction is started after the stationary for a predetermined time.

  As a result, the trainee can continue the training while maintaining the concentration with respect to the mark 20a reduced and displayed after the stop. Therefore, the training effect can be increased.

[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.
