1. A device to subjectively assess a user's reduced visual acuity, comprising:
a digital display;
a lenslet array disposed relative to said digital display to shape a light field emanating therefrom; and
a hardware processor configured to operate on pixel data for respective optotypes to output respectively adjusted pixel data to be rendered side-by-side by said digital display via said lenslet array so to respectively adjust the user's perception of said respective optotypes as rendered therethrough to thereby render, side-by-side, distinctly perceptively adjusted optotypes corresponding to respective visual corrections to subjectively assess the user's reduced visual acuity.
