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.
