Description

  The present invention relates to a portable visual acuity recovery training apparatus for training an imaging adjustment function of an eye.

  The decrease in visual acuity is thought to be due to a decrease in the imaging function of the eye due to the accommodation tension and weakness of the eye's regulatory muscles (the ciliary muscles). You can expect. In this method, the ciliary muscle is activated by training, and the perspective adjustment function is activated to restore the visual acuity.

  In view of this, a visual acuity recovery device that attempts to improve the visual acuity recovery effect by activating the function of the control muscle has been proposed (see, for example, Patent Document 1). This visual acuity recovery device reciprocates a gaze plate on which a mark is displayed, and moves the mark toward and away from a user (trainer). When the user of the apparatus gazes at the mark, the focus of the eye moves continuously between the short distance and the long distance, so that the accommodation muscle is efficiently trained. Furthermore, since the size of the mark is controlled so that the size projected on the retina is always constant between the far point and the near point, the trainer can concentrate more on training. However, since the eyesight recovery device reciprocates the gaze plate, the size of the device increases.

  Therefore, a portable visual acuity recovery is performed in which a mark is displayed on the electronic display means of the mobile phone, and the user holds the mobile phone in his hand and focuses and stretches the arm while focusing on the mark. Training devices have been proposed. This portable visual acuity recovery training device changes the size of a mark to be displayed according to the distance from the user. According to this portable visual acuity recovery training apparatus, the apparatus can be downsized and training can be performed easily.
