  • Patent number: 11382499
    Abstract: A remote eye examination method includes initiating a remote chat session between a local computing device coupled to a phoropter, and a remote computer, and initializing the phoropter for remote control by the remote computer. Then, a multi-colored lamp is activated in a first color until a determination that a refractory examination utilizing the phoropter has commenced. Thereafter, responsive to a determination that the examination has commenced, the multi-colored lamp changes to a second color, and movement of portions of the phoropter are commanded as directed by the remote computer, data is recorded into a patient record and a progression of the examination monitored. Finally, on condition that a threshold period of time before a conclusion of the refractory examination is detected, the multi-colored lamp changes to a third color and upon conclusion of the examination, a message transmitted to a remote account indicating access to the patient record.
