Abstract: A vision training device includes a housing having at least one eyepiece unit corresponding to an eye of a user, a display that displays a target image in front of a fixation axis of the user, a lens arranged between the eyepiece unit and the display unit, a movable unit capable of moving at least one of the display and the lens along the fixation axis, and a control unit that sets at least one training range within a movable range of the display and the lens and controls the movable unit such that at least one of the display and the lens is moved within the training range.

Abstract: It is an object of the present invention to provide a vision training device capable of performing color correction for a display and providing elaborate vision training. In order to achieve the above objects, a vision training device according to the present invention includes a color filter having an optical property disposed in a field of view direction of an eye of a user, a display, a user operating unit that adjusts image information of the display, and a control unit that causes a reference color image within a range similar to a color of the color filter to be displayed on the display and stores a correction confirmation signal for the display as a correction value when the correction confirmation signal is input through the user operating unit.

Abstract: It is an object of the present invention to provide a vision training device having an excellent vision training efficiency as vision training is performed in consideration of a status of personal vision.

Abstract: A vision training device includes a main body, a lens unit, a drive motor, and a controller. The lens unit includes a plurality of lenses respectively having different diopter values and a lens holder that supports the lenses. The drive motor moves the lens holder so that one of the lenses of the lens unit is disposed on a line of sight axis. The controller controls the drive motor such that a test lens selected from the plurality of lenses is disposed on the line of sight axis and stores an accommodation time indicating a period of time in which the eye becomes in an accommodated state to the test lens.

Abstract: A fluidic lens according to the present invention comprises: a first membrane and a second membrane which face each other; a first means for forming a magnetic field in the first membrane and a second means which exhibits a magnetic force with respect to an external magnetic field formed in the second membrane; a fluid chamber which forms a space between the first membrane and the second membrane and is filled with fluid; and a supplementary chamber connected to the fluid chamber, wherein the second means generates a magnetic force via the magnetic field generated by the first means, thereby causing attraction and repulsion between the first membrane and the second membrane to adjust the focal length of the lens.

Abstract: At least one of the first display and a second display move at least one of the left eye image and the right eye image such that a distance between the left eye image and the right eye image is increased. A separation confirmation signal is received indicating that the image focuses of the image do not coincide with each other in terms of fusion. Fusional amplitude information is stored indicating a separation distance between the left eye image and the right eye image when the image separation confirmation is input.
