Problems solved by technology

Therefore, it is possible that the trainer will no longer watch the visual target when he is bored, and may also stop the training action, which has the problem of being difficult to train for a long time
[0023] Moreover, if it is a short-term training, it may not be possible to relieve the tension of the eye ciliary muscles through training, and it may not be able to eliminate fatigue.

Embodiment Construction

[0051] figure 1 It is a configuration diagram showing an eye function training device according to an embodiment of the present invention.

[0052] Such as figure 1 As shown, the eye function training device 1 is composed of an optotype moving part 11 , a dichroic mirror 13 , an eye refraction measurement part 20 , a control part 21 and a display part 22 .

[0053] The optotype moving unit 11 is composed of an optotype 11a, a convex lens 11b, an optical axis direction moving unit 11c, and a left-right direction moving unit 11d.

[0054] Such as figure 1 As shown, the light emitted by the visual target 11a becomes close to the state of parallel light at the convex lens 11b, is reflected at the dichroic mirror 13, and then enters the eye 10 to be trained. Thus, from the trained eye 10, the position of the visual mark 11a appears to be farther than the actual position.

[0055] Although the optotype moving part 11 is not shown in the figure, two for the left eye and the ri...

Abstract

In a visual training device and a visual training method, different targets are displayed for right and left eyes, respectively, and refractivities of the right and left eyes are measured. Based on the measured refractivities of the eyes, positions of the targets displayed for the right and left eyes are moved in the directions of the respective optical axes. At the same time, the targets are moved so that the visual axes of the right and left eyes incline outward toward the end. The directions of the visual axes of the right and left eyes incline outward toward the end, so that it is possible to relax the strain of musculus ciliaris and relieve visual fatigue through short, effective training.

Description

technical field [0001] The present invention relates to an eye function training method and an eye function training device. Displaying an optotype to the trained eye, moving the optotype to the direction of the optical axis (the optical axis connecting the trained eye and the optotype), and moving the optotype to the direction of convergence or divergence (the optical axis to be trained) The left and right direction of the training eyes) to move the visual target, which is suitable for relieving the tension of the trained eyes. Background technique [0002] In today's information society, due to working close to screens such as TVs and personal computers, eyes tend to be abused. [0003] In normal work, the ciliary muscle repeatedly relaxes and tenses to adjust appropriately because the objects viewed by the eyes have various distances. [0004] However, if there is too much close work on a screen such as a PC, the eyes continuously look at objects at the same distance wit...
