A method for improving the visual acuity of a patient comprising the steps of: determining a vision loss relating to a degradation in a visual field of view of the patient; storing within the memory of a head mounted display a plurality of recipes, each recipe relating to configuration settings comprising a set of image modification software applications to be applied by a microprocessor of the head mounted display for correcting or enhancing the vision of the patient during a visual task of a set of visual tasks; establishing a region of interest for the patient; obtaining first image data relating to a field of view image to be viewed by the patient; obtaining second image data relating to a region of interest image to be viewed by the patient; applying with the microprocessor of the head mounted display a first set of image modification settings to at least one of the ROI image and the FOV image where the first set of image modification settings form part of a current recipe selected by the patient; applying with the microprocessor of the head mounted display a second set of image modification settings to the ROI image where the second set of image modification settings form part of the current recipe selected by the patient; composing a final image by over-writing that portion of either the obtained FOV image or the modified FOV image defined by the established ROI with the modified ROI image; and displaying the final image to the patient upon the head mounted display; wherein the patient can select a recipe using control features of the electronic device; the patient can make and use minor changes to a recipe using the control features of the electronic device; the patient can request either major changes to a recipe themselves or request changes to a recipe associated with a regulated activity using the control features of the electronic device but these cannot be implemented until either approved or activated by a professional ophthalmic oversight clinician; and the composed final image corrects for the determined vision loss of the patient. determining a vision loss relating to a degradation in a visual field of view of the patient; storing within the memory of a head mounted display a plurality of recipes, each recipe relating to configuration settings comprising a set of image modification software applications to be applied by a microprocessor of the head mounted display for correcting or enhancing the vision of the patient during a visual task of a set of visual tasks; establishing a region of interest for the patient; obtaining first image data relating to a field of view image to be viewed by the patient; obtaining second image data relating to a region of interest image to be viewed by the patient; applying with the microprocessor of the head mounted display a first set of image modification settings to at least one of the ROI image and the FOV image where the first set of image modification settings form part of a current recipe selected by the patient; applying with the microprocessor of the head mounted display a second set of image modification settings to the ROI image where the second set of image modification settings form part of the current recipe selected by the patient; composing a final image by over-writing that portion of either the obtained FOV image or the modified FOV image defined by the established ROI with the modified ROI image; and displaying the final image to the patient upon the head mounted display; wherein the patient can select a recipe using control features of the electronic device; the patient can make and use minor changes to a recipe using the control features of the electronic device; the patient can request either major changes to a recipe themselves or request changes to a recipe associated with a regulated activity using the control features of the electronic device but these cannot be implemented until either approved or activated by a professional ophthalmic oversight clinician; and the composed final image corrects for the determined vision loss of the patient.
