Abstract: Described are various embodiments of a digital display device for use by a user having reduced visual acuity. In one embodiment, a digital display device includes: a digital display medium including an array of pixels and operable to render a pixelated image; a diffractive light field barrier overlaying said digital display at a distance therefrom and defined by an array of diffractive optical elements, each of said diffractive optical elements defined by a concentrically patterned barrier centered over a corresponding set of said pixels to diffractively influence a light field emanating therefrom and thereby govern a projection thereof from said display medium toward the user; and a hardware processor operable to output corrected image pixel data to be rendered as a function of a stored characteristic of said diffractive light field barrier and a selected vision correction parameter related to the user's reduced visual acuity.
