         27 . The electronic device of  claim 26 , wherein a given user profile, and said designated vision correction parameter stored in association therewith, are rendered accessible in response to a corresponding user login via a distinct electronic device. 
     
     
         28 . The electronic device of  claim 26 , wherein the user vision correction prescription is automatically calculated from said designated vision correction parameter. 
     
     
         29 . The electronic device of  claim 21 , wherein said light-field optics layer comprises a lenslet array. 
     
     
         30 . The electronic device of  claim 21 , wherein said light-field optics layer is layered on or spaced from said single digital display screen. 
     
     
         31 . The electronic device of  claim 21 , wherein said hardware processor is operable to, in accordance with an image pre-filtering function, selectively activate individual pixels of the single digital display screen to output, in real-time, said correspondingly corrected adjusted image. 
     
     
         32 . A non-transitory computer-readable medium having instructions stored thereon for execution by a hardware processor to implement an application on an electronic device, the electronic device comprising a single digital display screen and a light-field optics layer, said instructions executable by said hardware processor to:
 adjust an adjustable vision correction parameter corresponding to vision correction prescriptions; and   correspondingly adjust an output image of the electronic device as said adjustable vision correction parameter is adjusted so to   output, in real-time, a correspondingly adjusted output image via said single digital display screen and said light-field optics layer until said correspondingly adjusted output image is observed by a user having a reduced visual acuity, via said single digital display screen and said light-field optics layer, to compensate for the user's reduced visual acuity and thereby define a user vision correction prescription therefor.   
     
     
         33 . A method comprising:
 rendering an output image for visualization by a user via a single digital display screen and a light-field optics layer;   adjusting said output image in accordance with an adjustable vision correction parameter corresponding to vision correction prescriptions to output a correspondingly adjusted output image via said single digital display screen; and   adjusting said adjustable vision correction parameter to output, in real-time, said correspondingly adjusted output image via said single digital display screen and said light-field optics layer until said correspondingly adjusted output image is observed by the user via said single digital display screen and said light-field optics layer to compensate for the user's reduced visual acuity and thereby define a user vision correction prescription therefor.   
     
     
         34 . A network-enabled system for use by users having reduced visual acuity, the system comprising:
 a network-accessible vision correction server; and   a software application executable on each of a plurality of electronic devices, each of said devices comprising a single digital display screen and a light-field optics layer, a hardware processor, a non-transitory computer-readable medium, and a network communication interface,   said software application comprising instructions executable by said hardware processor in adjusting an output image to be rendered by said single digital display screen in accordance with a designated image correction function,   wherein said image correction function receives as input an adjustable vision correction parameter that corresponds to vision correction prescriptions and that is adjusted to output, in real-time, a correspondingly adjusted output image until said correspondingly adjusted output image is observed by a given user via said single digital display screen and light field optics layer of a given one of said devices to compensate for a reduced visual acuity of said given user and thereby define a user vision correction prescription therefor.
