Description

  The present invention relates to a visual acuity recovery training device for recovering dynamic visual acuity, myopia, and the like.

  Currently, in the sports world, there are physical abilities suitable for athletic competition, but there are people who are suffering from weak visual abilities, such as low vision or shortsightedness, who cannot select their favorite sports due to their weak visual abilities. Under such circumstances, attempts have been made to recover dynamic visual acuity and myopia while playing training images using a machine.

  Although the dynamic visual acuity is used for inspection, for example, in Japanese Patent Application Laid-Open No. 2000-237133, an index moving horizontally, vertically, or diagonally on a flat screen is visually recognized from a position in front of the screen. An eyesight measurement device is disclosed.

  On the other hand, with regard to myopia, one of the causes is that the ciliary muscles, which are attached to the periphery of the lens, which is one of the components of the eye, and pull the lens, solidify in a tense state, and as a result, the lens remains thick Studies have shown that this is because they cannot focus on things that are fixed and far away. In order to recover such myopia, some training devices based on long-distance training have been considered.

For example, Japanese Patent Application Laid-Open No. 2001-061917 describes that an apparatus has been developed in which the focus of an eye is continuously moved to a short distance and a long distance while watching an index that reciprocates. Japanese Patent Application Laid-Open No. 08-257078 discloses an apparatus that changes an optical distance between an image viewed through an eyepiece and an eyeball by moving an LCD panel displaying an image back and forth with respect to the apparatus body. It is stated that it is being developed.
JP-A-2000-237133 JP-A-2001-061917 JP-A-08-257078

  However, in the case of dynamic visual acuity, for example, in ball games such as baseball and tennis, it is necessary to catch and hit a three-dimensional ball that moves at high speed in a three-dimensional space, as described in JP-A-2000-237133. With the technology described above, indices that move in a horizontal, vertical, or oblique direction on a flat screen can only be visually recognized from the front of the screen. It is not a training to see three-dimensional indicators that move quickly. Further, even if the index is devised so as to move back and forth in a three-dimensional manner on the screen, it is an image on the surface of the monitor screen and is not three-dimensional.

  On the other hand, in the case of myopia, the technique described in Japanese Patent Application Laid-Open No. 2001-061917 continuously moves the index from a long distance to a short distance or from a short distance to a long distance by using a physical driving unit. The effect is small from the viewpoint of training the ciliary muscle without abrupt switching between near and far. According to the technique described in Japanese Patent Application Laid-Open No. 08-257078, only the optical distance between the image and the eyeball is changed, that is, only the image moves in the screen of the eyepiece at a certain distance from the eyeball. Since the distance from the eyeball to the screen is constant, it is not a perspective with a change in three-dimensional distance, and is not an actual perspective training.

  Therefore, the present invention provides a training apparatus for dynamic visual acuity that allows a user to view an image three-dimensionally, and a myopia that uses an actual long-distance image and a short-distance image and that can instantaneously switch these at regular intervals. The present invention also provides a visual acuity recovery training device to which a function for performing various types of training, such as a training device or a combination thereof, is added as necessary.

  The configuration of the vision recovery training device according to the present invention, which has been implemented to solve this problem, will be described with reference to the common reference numerals used in the drawings showing the embodiments.

  Further, the eyesight recovery training apparatus according to the third aspect of the present invention supplies the apparatus body 1 having a viewing window 11 on the front surface of the apparatus as a dark room, and an image for performing the vision recovery training. An image supply unit for displaying an image supplied by the image supply unit; a main image display unit for displaying the image supplied by the image supply unit; An image reflecting unit 4 for reflecting the image (image A) displayed on the main image display unit 3 and an image (image B) reflected by the image reflecting unit 4 are located between the viewpoint and the image A. Image display unit 5 for displaying the reflected image as described above, and switching means 6 for instantaneously switching the reflected image display unit 5 between a first position and a second position. When the display unit 5 is at the first position, When the image B is seen without seeing the image A and the reflection image display unit 5 is at the second position, the visual acuity recovery training apparatus is configured to see the image A without seeing the image B. .

  Here, the first position is a position where the reflection image display unit 5 becomes a visual barrier with respect to the main image display unit 3, that is, the reflection image display unit 5 is visible from the viewpoint. However, the main image display section 3 means a set position of the reflection image display section 5 within a range where the main image display section 3 is blocked by the reflection image display section 5 and cannot be seen. The second position is a position at which the reflection image display unit 5 is moved from the first position, that is, the reflection image display unit 5 becomes invisible from the viewpoint, and the main image display unit 3 displays the reflection image display. The setting position of the reflection image display unit 5 is within a range in which the obstruction of the unit 5 is eliminated and the image can be seen. Therefore, switching between the first position and the second position includes not only switching between specific two points but also switching between positions in the wide range described above.

  According to the visual acuity recovery training apparatus of the first aspect of the present invention, in addition to the conventional dynamic visual acuity training, an index moving in a horizontal, vertical, or oblique direction on a plane screen is visually recognized from a position in front of the screen. Then, by changing the angle of the screen, it is possible to perform dynamic visual acuity training in which the indices are shown in a three-dimensional manner and the three-dimensional indices are visually recognized.

  According to the visual acuity recovery training apparatus of claim 2 of the present invention, by viewing the long distance image and the short distance image in which the actual distance is different and switching instantaneously, the ciliary muscle is trained to recover myopia. Can be planned.

  Another advantage of the present invention is that the reflection image display unit located at a short distance is located at a position serving as a visual barrier with respect to the main image display unit located at a long distance from the viewpoint. Therefore, when the reflection image display unit is visible, the main image display unit is not visible, and when the reflection image display unit is moved, the reflection image display unit becomes invisible and the main image display unit becomes visible, , And only one of the short-range images can be viewed.

  Subsequently, an outline of a method of using the device in each training will be described. First, the training of dynamic visual acuity is performed in the same manner as in the conventional example. However, as shown in FIG. 5, the rotating motor 34 is operated by the remote controller, and the monitor screen 32 is set so as to be in front from the viewpoint. By rotating the handle 86 in accordance with the visual acuity, the monitor 31 is moved back and forth, and stopped at an arbitrary position. By visually recognizing an index that moves vertically, horizontally, diagonally, or randomly on the monitor screen 32 fixed at the front position, it is possible to train a planar dynamic visual acuity. At this time, the motor 61 is stopped, and the reflection image display plate 52 is laid down.

  Next, as another example of the training of dynamic visual acuity, as shown in FIG. 6, the rotating motor 34 is operated by the remote control, and the monitor 31 is set by rotating the monitor 31 rightward from the front by 70 degrees from the viewpoint, The handle 86 is rotated in accordance with the eyesight of each person, the monitor 31 is moved back and forth, and stopped at an arbitrary position. Indices that move vertically, horizontally, diagonally, or randomly on the monitor screen 32 can provide perspective in the front-rear direction and the stereoscopic effect of the index as viewed from the viewpoint by the width of the monitor screen 32. By visually observing the perspective image of the index, training of three-dimensional dynamic visual acuity can be performed. At this time, the motor 61 is stopped, and the reflection image display plate 52 is set to fall down in the same manner as the training of a plane moving body visual acuity.

  Next, in training for myopia recovery, as shown in FIGS. 3 and 4, the monitor rotation motor 34 is operated by the remote controller, and the monitor screen 32 is set so as to be in front of the user from the viewpoint. By rotating the handle 86 in accordance with the human eyesight, the monitor 31 is moved back and forth, and stopped at an arbitrary position. The angle of the reflection plate 42 is set by adjusting the adjustment screw 91 in accordance with the set position of the monitor 31. Then, the motor 61 is operated to cause the reflection image display panel 52 to stand up and down at intervals of 6 seconds. By alternately viewing the image A (far-distance image) on the monitor screen 32 and the image B (short-distance image) projected on the mirror 51 of the reflection image display plate 52, training of distance and distance is possible. In addition, by alternately viewing the image A (large image) on the monitor screen 32 and the image B (small image) projected on the mirror 51 of the reflection image display plate 52, it is possible to perform large and small training at the same time.

  In addition, although not shown, an illuminating device that repeatedly turns on and off at regular intervals is provided in the device so that the monitor screen 32 can be alternately viewed in a bright environment and a dark environment, and the motor 31 is operated in a dark device. By doing so, it is also possible to perform lightness / darkness training such as alternately viewing the image A on the bright monitor screen 32 and the image B projected on the mirror 51 of the dark reflected image display plate 52 at intervals of 6 seconds.

  In addition, although not shown, training can be performed by listening to the audio simultaneously while watching the video by connecting headphones, and by gradually increasing the speed of the audio, training can be performed. When this is combined with the training of the dynamic visual acuity, it is possible to perform training that further enhances the exercise effect in which surrounding sounds can be quickly judged during exercise. Further, by gradually increasing the image speed, it is possible to speed up the transmission of a visually captured image to the brain, and to perform training for reducing the time required to see and judge objects and characters.

  Although the embodiment considered to be a representative example of the present invention has been described above, the eyesight recovery training device of the present invention is not limited to only the above-described embodiment, and includes the above-described constituent elements according to the present invention, and The present invention achieves the object of the present invention and can be implemented with appropriate modification within a range having the effects of the present invention.
