1. A light therapy system, comprising:
a lighting assembly operable to create a light output having a controllable illuminance;
a visual display for presenting a visual output to a user; and
a controller for controlling the lighting assembly to deliver a light therapy treatment, wherein the controller is operatively coupled to the lighting assembly and visual display, and adapted to:
receive a data input indicating a target melanopic luminous exposure for administration of the light therapy treatment by the lighting assembly;
receive a further data input indicative of one or more luminous characteristics of a visual output intended for presentation by the visual display;
determine based on the further data input an estimated additional melanopic luminous exposure associated with the intended visual output;
determine an adjusted target melanopic luminous exposure for administration of the light therapy treatment by the lighting assembly, based on reducing the target melanopic luminous exposure so as to compensate for the additional melanopic luminous exposure;
create, based on the adjusted target melanopic luminous exposure, a control schedule for controlling the illuminance of the lighting assembly over time such as to deliver in total over a defined treatment period the adjusted target melanopic luminous exposure; and
control the lighting assembly in accordance with the control schedule.
