The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a sensor and a processor operably connected to the sensor. The processor may be configured for receiving, from the sensor, sensor data representative of a vibration caused by the user. The vibration may be caused at least in part by one or more of a mouth of the user or an extremity of the user. The processor may be configured for determining a user instruction based on the vibration. The processor may be configured for causing the ophthalmic device to be controlled based on the user instruction.
