1. A subjective eye test device comprising:
an array of digital display pixels;
an array of light field shaping elements (LFSEs) shaping a light field emanating from said pixels toward a user pupil location;
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 of said defined optotype for a designated vision correction parameter associated with a given visual acuity level, and adjust said designated vision correction parameter, and thus said adjusted optotype pixel data, to accommodate for a distinct visual acuity level until an optimal visual acuity level is identified; and
an adjustable refractive optical system, interposed between said array of pixels and the user pupil location so to set a selectable refractive correction and thus further refract and thus redirect said light field, wherein said optimal visual acuity level is identified as a function of said designated vision correction parameter and said selectable refractive correction.
