A comfortability-tension threshold for a user is determined and a current pose of the user and a determined optimal pose are compared. The current pose and the determined optimal pose are mapped to an angle for adjusting on-screen content of a display of the computer system and the on-screen content of the display of the computer system is adjusted based on the angle.

There are provided a function recovery training system, a function recovery training device and a program making it possible to, by quantitatively grasping states of a plurality of biological functions of a subject (specifically, a plurality of functions related to vision including relationships with the brain and the optic nerve), easily, efficiently and effectively perform recovery training for the biological functions of the subject from a composite point of view. There is provided a function recovery training system 10 for performing training to recover biological functions of a subject, the function recovery training system including: evaluation means 11; program generation means 12; and storage means 13; wherein the storage means 13 holds: a standard program 101 capable of evaluating states of the functions to be evaluation criteria based on a plurality of function evaluation items; and evaluation-item-specific programs 102 making it possible to perform training individually for each of the plurality of function evaluation items; the evaluation means 11 executes the standard program 101 and evaluates criterial states of the functions based on a response from the subject; the program generation means 12 selects any of the evaluation-item-specific programs 102 that is for at least one of the plurality of function evaluation items based on the evaluated criterial states to generate a training program 103; and the evaluation means 11 executes the training program 103 and evaluates recovery states of the functions based on a response from the subject.

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.

A method for treating amblyopia in a patient includes: providing a virtual reality headset having a display that provides a first display to a left eye and a second display to the right eye; and manipulating one of the first display or the second display such that the manipulation encourages a patent's amblyopic eye to perform more work than the non-amblyopic eye.

Systems and methods for treating or detecting binocular vision disorders of a patient. The system, via a display, presents a dichoptic presentation with first and second portions of content that are separated on the display. The first and second portions of content are translated horizontally across the display to adjust the vergence demand of the user.
