Abstract

<P>PROBLEM TO BE SOLVED: To allow an ocular training tool to have a function of determining visual acuity and a means for confirming a result. <P>SOLUTION: A plurality of landmarks each to be a target are arranged at a prescribed interval in a string (2) of about 1-5m. One end of the string is fixed to a part of a building, or the like, so as to be horizontally even with eyes. Then, ocular exercise is performed by putting the other end (5) on the upper part of a nose being the center of both the eyes. Thus, it is called a block string. At least one of the landmarks has a disk shape (6), where at least more than one Landolt rings (8) are arranged on at least one plane part (7), and is slidably arranged on the string. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a binocular eyeball training device called a block string.

  A so-called block string, which has recently been introduced on the Internet and the like, has a tip of a thread 2 having a length of about 1 m to 5 m fixed to a wall or the like as shown in FIG. Apply a thread to the center of the nose and place at least one bead or the like (3a, 3b,...) On the thread at an appropriate position from the nose. First, mark the target bead (3c) 1m ahead. If you can see it clearly with your eyes only, and if you see a single thread, check that the other eye looks the same, then look at it with both eyes. In that case, it is said that these two yarns represent the line of sight, and the intersection of the yarns represents the place where both eyes are facing. If the thread 2 appears to intersect at the center of the mark 3c as shown in FIG. 2, it is said that the movement of the eyes of both eyes is normal. In addition, as shown in FIG. 3, if the thread 2 appears to intersect slightly before the mark 3c, the force to be directed outside the eyeball is slightly insufficient, and the force to be brought in is somewhat excessive, as shown in FIG. If it looks like it crosses a little behind the mark 3c, it is said that the force directed outward is slightly excessive and the force directed inward is slightly insufficient. In addition, when the thread 2 is seen just before the mark 3c and the two marks appear as shown in FIG. 5, the force directed toward the outside of the eyeball is insufficient, and as shown in FIG. 6, the thread 2 crosses considerably behind the mark 3c. If you can see, it is said that there is not enough power to get inside. As shown in FIG. 7, each eye looks darker, but when one eye becomes thin or disappears, it is said that both eyes cannot be used well at the same time.

  This is a self-diagnostic exercise that trains and moves the eyes close together (convergence), moves and forces the eyes away from the distance (divergence), and whether the coordinating power works normally. Is for. Training here refers to the image of a mark moving on the thread, moving the line of sight from the front to the back and from the back to the front from end to end of the thread. Reciprocating the eyeballs while gradually shortening the time, so that the yarn crossings do not disappear or shake during the process. This trains the muscles around the eyeball. In particular, this is a device for eye movement that is useful for sports in which a fast ball is followed by a ball game.

  The above-mentioned block string is capable of self-diagnosis and training of the movement and force that brings both eyes close (convergence power), and the movement and force that directs both eyes from near to far (divergence power). The results of discrimination and vision training could not be confirmed.

  Therefore, according to the present invention, several target marker beads are arranged at predetermined intervals on a thread having a length of about 1 m to 5 m, and one end of the thread is fixed to a part of a building or the like substantially horizontally. In the so-called block string in which the other end is applied to the upper nose of the center of both eyes to move the eyes, at least one of the several marks is disk-shaped and at least one or more in at least one plane portion. The above-mentioned problems were solved by providing an eyeball training device characterized in that a Landolt ring was provided and slidable on the thread.

  Further, the disk-shaped body provided with the Landolt ring is provided separately from the target mark, and is slidably and detachably provided on the yarn, and In order to solve the above problems, a distance mark is provided on the yarn or the yarn itself so that the length or distance can be recognized on the yarn having a length of about 1 m to 5 m.

  By adopting the above means, it is possible to move the eyeball from near to far, or from far to near, and not only force the muscles around the eye (convergence power, quiet power) but also immediately You can judge your own visual acuity and confirm the results of your visual acuity training, which is very useful as a dynamic visual acuity training device. .

  Place several target marks on a thread with a length of about 1m to 5m at a predetermined interval, fix one end of the thread horizontally to a part of the building, etc., and close the other end to both eyes. In a so-called block string that moves binocularly by applying to the upper nose at the center of the center, at least one of the several marks is disk-shaped, and at least one Landolt ring is provided on at least one plane portion. The eyeball training device is provided so that it can be attached and detached and slidable on the yarn, and a distance mark is provided on the yarn portion so that the distance can be recognized.

  FIG. 1 shows the state of use of the eyeball training device as described above, and shows the state where the end 4 of the thread is horizontally fixed to a wall or the like, which is sometimes fixed below or above the horizontal. It is also possible to use it.

  FIG. 2 to FIG. 7 are views showing the state visible with eyes as described above.

  FIG. 8 shows an embodiment of the present invention, in which at least one disc-like body 6 having a Landolt ring (8, 8a...) Provided on one plane 7 and target landmark beads or the like (3a, 3b). ..)) Instead, it is a perspective view when thread 2 is passed, and by doing so, it is possible to judge the visual acuity by oneself and to confirm the result of the visual acuity training. In this case, the through-hole 9 provided at the center of the disk-like body is preferably large enough to load the thread 2 passing through the center. Here, the disk-shaped body is not limited to a circle, but may be a polygonal body or other shapes.

  FIG. 9 is a front view of another embodiment of the present invention. In this case, a disk-like body 6a provided separately from the target marker beads (3a, 3b,...) Is inserted from the middle of the yarn. The slit 10 is provided from the edge toward the central through hole 9a so that it can be inserted at a desired location, and there is a convenient effect that a Landolt ring of an appropriate size can be arranged at an appropriate location.

  FIG. 10 is a partially enlarged view of another embodiment of the present invention. In this case, colors 11 and 12 are attached to the thread 2 so as to provide a distance mark on the thread 2 having a length of about 1 m to 5 m. The distance can be understood instantly, and the landmarks and discs can be placed immediately at appropriate positions. Of course, the yarn may be partially colored.

  As in the present invention, the disk-shaped body provided with the Landolt ring can be arranged at an appropriate position, so that the disk-shaped body can be easily moved, and the position of the disk is changed to stare at the Landolt ring. It became possible to train not only the muscles around the eyeball but also the ciliary muscles.
