A system and method for evaluating visual acuity using a computerized or otherwise digitalized adaptive vision test is disclosed. The digitalized system presents users with a series of displays wherein each display presents three vertically aligned optotypes wherein the top optotype is the largest, the middle optotype is smaller, and the bottom optotype is of size between the top and middle optotypes. Alternatively, at times all three optotypes are equal in size. The system may adjust the difficulty of the upcoming display(s) based on user responses, such that correct identification of optotypes may trigger a reduction in the middle letter's size, accelerating convergence to the user's acuity threshold while minimizing visual fatigue.

A digital platform for determining a subject's visual acuity, said platform including;
A digital platform for assessing a user's visual performance, the platform comprising a display module configured to present a series of vertically arranged columns of optotypes, wherein each column comprises optotypes of varying sizes, and wherein the selection of each subsequent column is dynamically determined based on the user's response to the preceding column, whereby each display module comprises a vertical single column, wherein the display platform displays optotypes in a single vertical row, with each line of the column comprising a single optotype, whereby the vertically arranged optotypes vary in size relative to one another, with a size difference of approximately 0.1 LogMAR between optotypes.
A method for determining a user's visual performance the method comprising a digital platform wherein the platform displays a series of screens, wherein each screen presents a vertical column comprised of optotypes, such that in each subsequent screen optotypes are grouped and regrouped in vertical columns, wherein the platform first presents a series of screens with shifting optotype sizes to determine a user's general vision threshold, and wherein the platform second presents a series of screens with a narrower size range of optotypes to further refine the users visual performance score.
