System and method for the treatment of amblyopia

A system comprising:

• a display system configured to deliver a first image to a first eye of a subject and a second image to a second eye of a subject;
• a data processing apparatus coupled to the display system, the data processing apparatus configured to execute one or more computer programs stored on computer-readable storage medium
• to perform operations comprising:
• receiving the first image and the second image,
• identifying a delay factor associated with the second image,
• presenting the first image on a portion of the display system visible to the first eye of the subject, and
• delivering, in accordance with the delay factor, the second image to the second eye of the subject, wherein at least a portion of the second image is delivered 1-1000 msec before or after the first image, the second image being visible to the second eye concurrently with the first image being visible to the first eye,
• wherein the data processing apparatus is configured to alter a contrast of the second image such that the contrast of the second image is different from a contrast of the first image, and
• wherein the delay factor is identified based on measuring one or more parameters at each of multiple candidate delay factors.
