Systems and methods for adjusting display settings to reduce eye strain of multiple viewers

A system for reducing eye strain for multiple viewers, the method comprising control circuitry configured to:

• detect that a first viewer and a second viewer are consuming content from a device, wherein the content is generated for display according to a first display setting;
• calculate, for the first viewer, based on eye activity of the first viewer, a first metric that represents a degree of eye strain of the first viewer;
• calculate, for the second viewer, based on eye activity of the second viewer, a second metric that represents a degree of eye strain of the second viewer;
• determine whether the first metric is within a first range indicating an acceptable degree of eye strain for the first viewer and whether the second metric is within a second range indicating an acceptable degree of eye strain for the second viewer;
• and
• in response to determining that the first metric is not within the first range, or that the second metric is not within the second range:
• identify, for the first viewer, a first subset of display settings that are known to cause the first metric to be within the first range and, for the second viewer, a second subset of display settings that are known to cause the second metric to be within the second range;
• identify a third subset of display settings wherein the third subset of display settings comprises display settings that are in both the first subset and the second subset;
• select a second display setting that is within the third subset;
• and
• generate for display the content according to the second display setting.
