Abstract
Systems, devices, and methods for conducting an eye examination for visual acuity are provided. In one example, a system may include an optical subsystem positioned in front of one or both eyes of a user. The optical subsystem may comprise a handheld device or a head worn device, a visual indicator, and a plurality of vision modifiers. The system may determine a distance between the optical subsystem and the display based on comparing a fixed size of the visual indicator to a detected size of the visual indicator in an image obtained by a camera. The system may output an eye examination image for visual acuity based on the distance being within a valid range. The eye examination image may include a visual stimulus having an output size determined based on the distance. The system may receive an input from the user indicating a selection of the visual stimulus.
