Abstract: A wearable device for administering an electroretinography examination to a wearer can have a housing that defines a first and a second compartment. Each of the first and second compartments can comprise: a stimulation light source, a focal light source, an active electrode that is configured to engage skin of the wearer, and a reference electrode that is spaced from the active electrode and configured to engage skin of the wearer. A processor can be communicatively coupled to the stimulation light source, the active electrode, and the reference electrode of each of the first and second compartments of the housing. A memory can be in communication with the processor. The device can perform a method comprising: causing the stimulation light source of the first compartment to flash; and storing a signal from the active electrode of the first compartment. The housing can further comprise a ground electrode.
