Systems, devices, and methods for electrophysiological recording from the eye are disclosed herein. An electroretinography device can detect a biopotential signal from an eye of a subject and transmit the same to a processor. Embodiments of the present technology include one or more features directed to improving the use and operability of an electroretinography device. For example, the device can include features for (i) inhibiting multiple devices from adhering or sticking to one another or a different object and (ii) providing tactile feedback to users to help distinguish one side of the device from the other.

Disclosed herein are systems and methods for sensing electrophysiological signals using dynamically changing lead configurations. A garment system is provided, the system having a plurality of electrodes, each disposed to contact a respective body portion of a plurality of body portions of a wearer of the garment system. Electrophysiological signals of the wearer are sensed in a first lead configuration of the garment system using a first subset of the electrodes. At least one change in contact location is detected between the electrodes and the body portions. Upon such detecting, further electrophysiological signals of the wearer are sensed in a second lead configuration of the garment system using a second subset of the electrodes. The second lead configuration may provide an improved signal quality relative to the first lead configuration.
