Abstract

Claims (13)

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.

2. The device of claim 1 , further comprising an adjustable refractive optical system disposed relative to said digital display so to set a selectable common refractive correction and thus further refract and thus redirect said light field, wherein each of said respective visual corrections is further defined as a function of said selectable common refractive correction.

3. The device of claim 2 , wherein said selectable common refractive correction is selectable to define a common coarse refractive correction for each of said respective optotypes, whereas said respectively adjusted pixel data further refines said respective visual corrections.

4. The device of claim 2 , wherein said adjustable refractive optical system comprises a tunable lens.

5. The device of claim 1 , wherein said respective optotypes comprise identical optotypes that are distinctly perceptively adjusted for subjective comparison.

6. The device of claim 1 , wherein said respectively adjusted pixel data digitally maps each of said respective optotypes to a corresponding virtual image plane virtually positioned relative to the digital display at respectively corresponding perceived image depths.

7. The device of claim 1 , wherein said respectively adjusted pixel data digitally maps each of said respective optotypes to a retinal plane in accordance with said respective visual corrections based on respective eye focus parameters.

8. The device of claim 1 , wherein said distinctly perceptively adjusted optotypes are rendered side-by-side in respective quadrants.

9. The device of claim 1 , wherein said distinctly perceptively adjusted optotypes are rendered side-by-side in a 2-dimensional grid.

10. The device of claim 1 , wherein said respective visual corrections are dynamically variable so to subjectively assess the user's reduced visual acuity.
