Using a 3d display to train a weak eye

A method of training a first viewer-eye, comprising:

• causing a 3D display system to display a first perspective of an image and a second perspective of the image;
• determining an eye-strength of the first viewer-eye with respect to an eye-strength of a second viewer-eye, wherein the first perspective is intended for display to the first viewer-eye, and wherein the second perspective is intended for display to a second viewer-eye;
• and
• varying, based at least in part on the determined eye-strength of the first viewer-eye, display characteristics of at least one of the first perspective and the second perspective.

An eye-monitoring system for controlling a 3D display system displaying a plurality of perspectives, the eye-monitoring system comprising:

• an eye sensor configured to detect characteristics of a plurality of viewer-eyes;
• a display-system control interface communicatively connecting the eye-monitoring system to the 3D display system;
• and
• control circuitry configured to:
• (i) generate, based at least in part on characteristics detected by the eye sensor, eye-strength data indicative at least of an eye-strength of a weak viewer-eye from the plurality of viewer-eyes, and
• (ii) output command signals to the 3D display system via the display-device control interface, wherein the command signals instruct the 3D display system to vary the display characteristics of one or more of the plurality of perspectives in accordance with the generated eye-strength data.
