A system comprising: a display device; a sensor to measure a property related to a distance between the display device and a user; a computing device comprising: a memory storing computer-executable instructions; and a processor to execute the computer-executable instructions to at least: launch at least one module related to a low contrast visual acuity test; display a graphical user interface on the display device, wherein the GUI corresponds to the low contrast visual acuity test; conduct the low contrast visual acuity test by: calculating the distance between the display device and the user based on the property measured by the sensor; when the distance between the display device and the user is within a test value, administer the low contrast visual acuity test to the user using the GUI by executing the at least one module to present a series of vector-type images that are scaled based on the distance; receiving inputs from the user via the GUI based on the series of vector-type images being presented to the user; determining a score for the user based on a number of the inputs comprising answers within a normal range; and determining a visual status of the user based on the score. a display device; a sensor to measure a property related to a distance between the display device and a user; a computing device comprising: a memory storing computer-executable instructions;
