Claim 21:
22. A non-transitory computer-readable medium comprising digital instructions to be executed by one or more digital processors to digitally implement a subjective eye test, by:
setting a designated vision correction parameter associated with a given visual acuity level;
adjusting user perception of a defined optotype rendered by an array of digital display pixels via a corresponding array of light field shaping elements (LFSE) to at least partially accommodate said given visual acuity level by:
digitally associating with a given pixel, given a corresponding LFSE and a user pupil location, an adjusted optotype pixel value designated for an adjusted image location set for said designated vision correction parameter; and
rendering each said given pixel according to said adjusted 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.
