Light field device, pixel rendering method therefor, and adjusted vision perception system and method using same

Abstract

Described are various embodiments of a device to subjectively assess a user's reduced visual acuity. In one embodiment, the device includes: a digital display; a lenslet array disposed relative to the digital display to shape a light field emanating therefrom; and a hardware processor. The hardware processor operates on pixel data for respective optotypes to output respectively adjusted pixel data to be rendered side-by-side by the digital display via the lenslet array so to respectively adjust user perception of the 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.
