Claim 3:
4. The method of claim 1, further comprising, concurrently with ‘a’ and ‘b’:
d. determining a gaze direction of a second eye of the subject viewing a second eye display screen and providing said determined gaze direction to a computer processor;
e. subsequent to ‘c’, based on said determined gaze direction of the second eye, with a computer processor generating a second display image for display to the second eye on said second eye display screen from said received digital base image, wherein:
i. a central-vision portion of said second display image that corresponds to a portion of the field of view of the second eye that includes said determined gaze direction is either:
unmodified compared to a corresponding portion in said base image; or
modified so that visual characteristics of said central-vision portion of said second display image are changed compared to corresponding visual characteristics of a corresponding portion in said base image which modification improves the image quality of said central-vision portion relative to the corresponding portion in said base image, and
ii. a non-central vision portion of said second display image that is different from said central-vision portion is either:
unmodified compared to a corresponding portion in said base image; or
modified so that visual characteristics of said noncentral vision portion of said second display image are changed compared to corresponding visual characteristics of a corresponding portion in said base image,

wherein as a result of said generating, an image quality of said non-central vision portion of said second display image is lower than the image quality of said central-vision portion of said second display image; and
f. displaying said generated second display image on said second eye display screen so that the second eye of the subject views said second display image on said second eye display screen, wherein said non-central portion of said second display image is modified so that visual characteristics of said non-central vision portion of said second display image are changed compared to corresponding visual characteristics of a corresponding portion in said base image which modification degrades the image quality of said non-central vision portion relative to the corresponding portion in said base image, wherein said modification which degrades the image quality of said non-central vision portion relative to the corresponding portion in said base image includes at least reduced contrast.
