Claim 0:
1. A subjective eye test device comprising:
an array of digital display pixels;
a corresponding array of light field shaping elements (LFSEs) shaping a light field emanating from said pixels toward a user pupil location; and
a hardware processor operable on pixel data for a defined optotype to output adjusted optotype pixel data to be rendered via said LFSEs to dynamically adjust user perception at the user pupil location of said defined optotype as rendered therethrough by:
digitally associating with a given pixel, given a corresponding LFSE and the user pupil location, an adjusted optotype pixel value designated for an adjusted image location set for a designated vision correction parameter associated with a given visual acuity level;
rendering each said given pixel according to said adjusted optotype pixel value, thereby rendering a perceptively adjusted version of said defined optotype viewable at the user pupil location that at least partially accommodates said given visual acuity level; and
adjusting said designated vision correction parameter to accommodate for a distinct visual acuity level until an optimal visual acuity level is identified.
