A wearable ocular surface temperature monitor apparatus used to measure ocular surface temperatures can be mounted around on eye sockets or can be engaged with glasses. The apparatus comprises a frame and an ocular temperature monitor modular disposed on the frame. The ocular temperature monitor modular further includes a plurality of temperature sensors, a signal processing circuit and a transceiver circuit. The temperature sensors are aligned with ocular surfaces for measuring temperatures. The wireless transceiver circuit reads and records the electrical signals output from the temperature sensors, and outwards wirelessly transmits them by the transceiver circuit.
