3. 3 . The visual function training system according to claim 1 , further comprises: a configuration information storage unit that stores information indicating which of the user's eyes has higher visual acuity; wherein the display control unit controls to increase the transparency of the object displayed on the first or second display device that displays the image to the eye indicated by the information stored in the configuration information storage unit.
4. 4 . The visual function training system according to claim 1 , further comprises: first and second cameras that capture the user's field of vision; and an image acquisition unit that acquires first and second images captured by the first and second cameras; wherein the display control unit detects the object from the first and second images and increases the transparency of a region of the object in the first or second image.
5. 5 . A visual function training method comprising: a computer executing a step of controlling an object to be operated by a user, which is displayed on a first display device that displays an image to one eye of the user and on a second display device that displays an image to an opposite eye of the user, to have different transparencies on the first and second display devices.
6. 6 . A program for causing a computer to execute a step of controlling an object to be operated by a user, which is displayed on a first display device that displays an image to one eye of the user and on a second display device that displays an image to an opposite eye of the user, to have different transparencies on the first and second display devices.

Description

TECHNICAL FIELD This invention relates to a visual function system, a visual function method and program. BACKGROUND ART A visual function method that changes how the right eye and left eye see using a headset has been proposed (see Patent Literature 1). CITATION LIST Patent Literature [PTL 1] International Publication No. 2017/181010 SUMMARY OF INVENTION Technical Problem However, as in Patent Literature 1, changing the view of the entire space for each eye makes it difficult to concentrate on the work object that should be focused on. Also, changing the contrast, brightness, or darkness of the work object makes the object stand out even more. This invention has been made in view of this background, with the purpose of providing a technology that can train vision. Solution to Problem The principal invention to solve the above problem is a visual function system comprising: a first display device configured to display an image to one eye of a user; a second display device configured to display an image to an opposite eye of the user; and a display control unit configured to control an object to be operated by the user, which is displayed on the first and second display devices, to have different transparencies on the first and second display devices. Other issues disclosed in this application and their solutions will be clarified in the “Description of Embodiments” section and in the drawings. Advantageous Effects of Invention According to this invention, it is possible to train visual function. BRIEF DESCRIPTION OF DRAWINGS FIG. 1: A diagram showing an example configuration of the binocular visual function training system according to this embodiment. FIG. 2: A diagram showing an example configuration of HMD 1. FIG. 3: A diagram showing an example software configuration of computer 2. FIG. 4: A diagram showing an example of an image displayed on HMD 1. FIG. 5: A diagram showing another example of an image displayed on HMD 1. FIG. 6: A diagram explaining the operation of computer 2 in the binocular visual function training system of this embodiment. DESCRIPTION OF EMBODIMENTS Overview The following is a description of a binocular visual function training system according to one embodiment of this invention. In this embodiment of the binocular visual function training system, a user wears a head-mounted display (HMD 1) and performs operations in a virtual space. By making the transparency of the object to be operated on different for the right eye and the left eye, training can be provided for users with amblyopia. FIG. 1 is a diagram showing an example configuration of the binocular visual function training system according to this embodiment. The binocular visual function training system of this embodiment includes computer 2. The computer 2 is connected to HMD 1 and input device 3, can accept data input from input device 3, and can control the display of images on HMD 1. As shown in FIG. 1, the computer 2 can be equipped with CPU 201, memory 202, and storage device 203. The storage device 203 is, for example, a hard disk drive, solid state drive, or flash memory that stores various data and programs. Each functional part of the computer 2 described below is realized by CPU 201 reading a program stored in storage device 203 into memory 202 and executing it, and each storage part of the computer 2 can be realized as part of the storage area provided by memory 202 and storage device 203. The input device 3 is, for example, a controller. The input device 3 can support the user in making predetermined inputs in the virtual space. Input device 3 can be configured, for example, as a set of left-hand and right-hand controllers. Input device 3 can be equipped with, for example, operation trigger buttons, infrared LEDs, sensors, joysticks, menu buttons, etc. The input device 3 can also detect posture and movement using an acceleration sensor (not shown) and input posture and movement data to the computer 2 as input data. The computer 2 can execute control processing to display a virtual object (three-dimensional object) to be operated on in HMD 1, move a virtual hand in response to input from input device 3, and allow the user to perform operations on the operation object through the movement of the virtual hand. FIG. 2 is a diagram showing an example configuration of HMD 1. HMD 1 can be worn on the user's head. HMD 1 is equipped with display devices 11 and 12 to be placed in front of the user's left and right eyes. Display device 11 displays an image to one eye (the right eye in the example in FIG. 2). Display device 12 displays an image to the other eye (the left eye in the example in FIG. 2). For display devices 11 and 12, for example, optical transmissive and non-transmissive displays can be employed. As described below, the transparency of the object to be operated on displayed on display devices 11 and 12 is controlled to be different. FIG. 3 is a diagram showing an example of the software configuration of th
