1. An eye drop bottle storage unit for eye drop administration compliance, the eye drop bottle storage unit comprising:
one or a plurality of eye drop bottle pods, wherein each eye drop bottle pod of the one or said plurality of eye drop bottle pods is configured to hold an eye drop bottle, and comprises one or a plurality of capacitive sensors, and a housing with a first set of connectors on a first side of the housing and a second set of connectors on a second side of the housing;
a memory configured to store data of an eye drop administration regime of a subject; and
a processor configured to receive signals from the one or said plurality of capacitive sensors of each eye drop bottle pod, and to determine from the received signals whether the subject administered eye drops into eyes of the subject from each eye drop bottle respectively held in each eye drop bottle pod of the one or said plurality of eye drop bottle pods in accordance with the eye drop administration regime data by computing change in the volume of a liquid in each eye drop bottle using capacitance measurements computed from the signals received from the one or said plurality of capacitive sensors.
