1. A visual aid device for cooperative coupling to a digital display to render a selected portion of an image rendered thereon to be viewed by a viewer having reduced visual acuity, the device comprising:
a complementary light field display configured to be operatively coupled to the digital display and to receive therefrom pixel data associated with the selected portion of the image to be rendered via said complementary light field display; and
a hardware processor operable on said pixel data to produce a vision-corrected portion of the image corresponding to the selected portion that at least partially addresses the viewer's reduced visual acuity when viewing said vision-corrected portion as rendered by said complementary light field display.
