Method and apparatus for treating diplopia and convergence insufficiency disorder

A method of treating diplopia or convergence insufficiency disorder in a patient comprising:

• providing a patient having a condition of diplopia or convergence insufficiency disorder with an image pair configured to present a first image to a first weaker eye of said patient and a second image to a second dominant eye of said patient, wherein information content of said first image perceivable by said first eye is different from information content of said second image perceivable by said second eye, and wherein the perceptibility of said information content of said first image is augmented in comparison to the perceptibility of said information content of said second image as a result of a difference in at least one image parameter of said first image and said second image;
• obtaining performance information of said patient when said patient performs a task requiring the perceiving of at least said information content of said first image;
• and
• adjusting, based on said performance information, when said performance information is indicative of an improvement of said patient's diplopia or convergence insufficiency disorder symptoms, said at least one image parameter such that said difference in perceptibility of said information content of said first image and said information content of said second image is reduced.
