ない。2. Description of the Related Art In recent years, with the accelerated spread of video game machines, the time for children to stare at a display screen of a television has increased. In addition, word processors and personal computers have become widespread in many fields such as business, and the time for staring at a display screen is rapidly increasing.
Staring at a display screen with a small change in luminance for a long time causes the three types of muscles of the eye, namely, the iris, extraocular muscles, and ciliary body to become tensed and stiff, and the eyes undergo pseudo myopia and eventually become pseudomyopic. Progresses to a myopic state. Under the circumstances where the deterioration of children's eyesight due to the spread of video games and the chronic fatigue of eyes due to the occupational use of word processors and personal computers have become major problems, the measures currently being taken are reluctant to limit the use time. It is nothing but a thing.

For example, a method of moving a coin in front of a body in accordance with a certain rule and staring at the coin (Kazuhiro Nakagawa, Paul AA).
Harris) and eye exercises proposed by US ophthalmologist Harold Pepperd based on the theory of ophthalmology by William Horatio Bates. Also, there is a commercially available device called MD-SS type vision training machine developed by Miyoko Sassa (medical doctor, ophthalmologist) for performing focus adjustment function training by automatically changing the distance to the index plate.

Trainees are currently frustrated in the middle of treatment. In addition, the current eyesight recovery training is
Each muscle, i.e., iris, extraocular muscle, and ciliary body, requires a long training time each time to perform the training individually, and the training content also depends on the procedure, time distribution of each training item, and the number of repetitions. It is meticulously determined and it takes patience to get used to training without being aware of them, which can be painful for children.

れている。FIGS. 2 and 3 show an example in which the display screen of the image display 10 changes sequentially every two to three seconds when the visual acuity training processing unit is activated. First, FIG. 2A shows two low-luminance backgrounds (in this example, black) in a state of being gathered at the center of the screen and composed of two different shapes.
A group of figures having a higher luminance (white in this example) than the background is displayed.

As shown in ()), the figure groups are gathered and become the same state as the first (a). At this time, the focal length of the eye changes close to looking far away when looking at a group of figures that are discrete, and changes to a state looking near when looking at a group of figures that gather, It will promote ciliary body movement.

促進されることになる。More specifically, at the time of discrete / set of the group of figures, if the figure on the left side of the group of figures is gazed at the left eye and the figure on the right side is gazed at the right eye, the convergence movement of both eyes will occur when the figures are assembled. (Eye movement in which the eyes of both eyes are directed inward), and divergence movement (eye movement in which the eyes of both eyes are directed outward) when discrete. Here, there is a close relationship between the convergence / divergence movement and the focal length adjusting action of the eye. It is known that even when the distance between the display screen and the eye is constant, the focal length adjusting action is easily induced. For example, when the group of figures is discrete, the distance perceived by so-called binocular parallax tends to change from the near point to the far point, and the ciliary body moves so as to adjust the focal length of the eye accordingly. Will be promoted.

同時に促進することとなる。Next, from (e) to (f) and (g), the figure group is discretely moved at the same time while moving the center of gravity of the figure group to the right of the screen. Subsequently, as shown in (h) and (i), the positions of the centers of gravity of the figure groups are further moved rightward on the screen, and conversely, they are simultaneously gathered. At this time, the movement of the extraocular muscles is promoted by pursuing the group of figures for which the position of the center of gravity is moved by the eyes, and at the same time, the movement of the ciliary body is also promoted as described above.

(Change from white to black in this example). At this time,
The instantaneous switching of the luminance of the background, which occupies a large area of the entire screen, from low luminance to high luminance causes a contraction reaction of the pupil, that is, light reflection. In this embodiment, an example is shown in which the background and the group of figures are switched from black to white and from white to black, respectively. It is not limited to the example. Where (v) to (w), (x),
As shown in the order of (y), (z), (a), (b), (c), and (d), in the state where the background is switched from the low-luminance background to the high-luminance background, the position of the center of gravity is changed. In order to repeat the set while repeating, the opening and closing adjustment movement of the iris, and extraocular muscles,
Ciliary body movement will be promoted at the same time.

Alternatively, the luminance also changes (in this example, the color changes from black to white). At this time, the luminance of the background, which occupies most area of the entire screen, is instantaneously switched from the high luminance to the low luminance. Here, as shown in the order of (e) to (f), (g), (h), and (g), in a state where the background is switched from the high luminance background to the low luminance background, the figure group is the center of gravity of the figure group. In order to change the position from diagonally upper left to diagonally lower right, the opening and closing adjustment movement of the iris,
And the movement of the eye muscles is promoted at the same time. Further, after (g), the screen display state is changed by the parallel execution of the respective means arbitrarily determined in advance.

間変化はこれに限定されるものではない。Here, in the above-mentioned series of screen display changing processes, the figure group display is reduced so that the contrast with the background color is reduced irrespective of the state of the figure group being discrete, set, or the position of the center of gravity. Changing the color in a timely manner is very effective in relieving tension during training, and at the same time, when the display color before the change is restored, that is, when the contrast with the background color increases again, the trainee's It has the effect of raising attention and increasing the concentration of attention to the figure, and is effective in maintaining training under moderate tension until the end. In this embodiment, the contrast with the background color is reduced every other screen in the drawing, that is, in a period of 4 to 6 seconds, such as (b), (d), (f), and (h) in FIG. An example in which the figure group display color is changed is shown. However, the time change of the figure group display color is not limited to this.

運動させることを目的としたものである。In the background color switching, the reason why the display time of the low-luminance background is relatively long and the display time of the high-luminance background is relatively short is that the pupil diffusion speed at the time of light-shielding reflection is high. Because it is very slow compared to the contraction speed at the time of light reflection, it is necessary to secure enough time for the pupil to dilate, and to stare at the high-luminance screen for a long time before training by the vision training apparatus according to the present invention. In many cases, the pupil is in a state of contraction for a long time, so that the iris is moved more in the direction in which the pupil is dilated.

点では同一である。FIGS. 4 and 5 show another example in which the display screen of the image display 10 changes sequentially. Compared with the above-described embodiment shown in FIGS. 2 and 3, the order of the figures is different, but a group of figures having two different shapes moves the position of the center of gravity of the group of figures, and discretely sets, or Both occur at the same time, and the background color of the figure group instantaneously changes from low luminance to high luminance, or from high luminance to low luminance, so that the opening and closing adjustment movement of the iris, the extraocular muscle, and the hair They are the same in terms of effectively promoting body movement.

非常に有効である。In the embodiment shown in FIGS. 4 and 5,
Unlike the embodiment shown in FIGS. 2 and 3, when the group of figures is discrete, the area of each figure constituting the group of figures decreases, and when the group of figures collects, The area of each figure constituting the group increases. This means that it is possible to easily recognize that the figure group has transitioned from the discrete state to the aggregate state or from the aggregate state to the discrete state by the size of each figure constituting the figure group. ,
Since the operation of the next screen can be easily predicted, it is very effective in reducing the tension during the training of the trainee and enhancing the effect of the training for preventing vision loss.

下防止訓練の効果を高めることも可能である。In addition to this, for example, the contrast between the display color and the background color of each figure is increased when the group of figures is discrete, and the contrast is reduced when the groups are aggregated. By increasing the contrast at the time of gathering, it is also possible to easily predict the operation of the next screen, reduce the tension during the training of the trainee, and enhance the effect of the training for preventing vision loss.

労回復等に極めて有効である。In particular, of the three muscles of the eye, the iris is a muscle involved in opening and closing the pupil, the extraocular muscle is a muscle involved in omnidirectional movement of the eyeball, and the ciliary body is a muscle involved in a focusing movement that changes the thickness of the lens. However, there is a clinical report that considerable focusing is possible even with an aphakic eyeball ("Ophthalmology Mook", 3
Page 7, no. 3, 1978), and the eye of William Horatio Bates, who contracts and relaxes the extraocular muscles to change the shape of the entire eyeball and adjusts the focus by changing the distance from the lens to the retina. As is suggested by myology, it has been found that focusing movement alone acts not only on the ciliary body but also on other muscles. Since the device of the present invention acts on three types of muscles of the eye simultaneously and comprehensively as described above, it is extremely effective in preventing a decrease in visual acuity and recovering from asthenopia.

運動のみを意識することが肝要である。In addition, due to the convergence / divergence movement of the eyes, the ciliary body relaxes and contracts in a healthy person, which is equivalent to a focus adjustment usually from about 20 cm to about 5 m (“Three-dimensional / depth perception” Kenya Uomori) Others, Journal of the Institute of Television Engineers of Japan, Vol.
No. 12 1994). Therefore, by gazing at the discrete / set of figures in the apparatus of the present invention, the focal length adjusting action of the eye, that is, the relaxation / contraction movement of the ciliary body, can be promoted over a wide range. However,
The distance between the display screen of the figure group and the eyes is usually almost constant (2
(Approximately 0 to 30 cm), when the group of figures is discrete, it gradually falls outside the depth of focus, causing a phenomenon that the figures appear blurred. If you try to see this forcibly, it will strain your eyes,
It is important to take blurring as a matter of course and be aware of only convergence and divergence movements.

である。In the light reflection, when the illuminance gradually increases, the pupil does not easily contract even if the illuminance difference is large, but if the illuminance increases rapidly, the pupil contracts even if the illuminance difference is small. Conversely, in light-shielding reflection, rapid light shielding causes pupil dilation, but the reflection speed (the speed from the light-shielding to the maximum pupil diameter) is low (75% of the maximum pupil diameter). There is a fact that it takes 5 seconds to enlarge ("Physiology of the eye" by Ryosaku Otsuka, 1966, published by Medical Shoin). Therefore, it is necessary to give a sharp luminance change (from high luminance to low luminance or from low luminance to high luminance) on the display screen in order to start the opening / closing adjustment movement of the iris in the training for preventing eyesight deterioration, and also to make the pupil sufficiently It is effective to make the display time of the low-luminance screen relatively long in order to increase the display time.

It has a further effect on preventing fatigue.
