Systems and methods for automated subjective refractions

A method of administering a subjective refraction test, the method comprising:

• generating a first set of conditions for a first test and a first plurality of response fields, the first set of conditions corresponding to a first visual reference viewed by a patient through a first combination of a plurality of lenses and the first plurality of response fields configured to receive first feedback from the patient indicative of the patient's vision under the first set of conditions;
• receiving a first input indicative of the patient's vision under the first set of conditions;
• automatically displaying, based on the first input, an updated first visual reference viewed by the patient;
• iteratively updating, based on the first input, a second combination of the plurality of lenses and maintain the first plurality of response fields and receive feedback from the patient until a predefined number of responses are received during the first test to determine an endpoint for the first test;
• automatically generating and displaying, based on the determined endpoint for the first test, a second set of conditions for a second test and a second plurality of response fields, the second set of conditions comprising a second visual reference viewed by the patient and a third combination of the plurality of lenses, and the second plurality of response fields configured to receive second feedback indicative of the patient's vision under the second set of conditions;
• receiving an updated input indicative of the patient's vision under the second set of conditions;
• and
• determining an endpoint for the second test based on a determined a visual acuity during the second test matching a predefined visual acuity value.

A system for administering an automated subjective refraction test, the system comprising:

• a processing circuit coupled to a phoropter having a plurality of lenses that are adjustable and a display device configured to display a plurality of visual references, the processing circuit configured to:
• generate a first set of conditions for a first test and a first plurality of response fields, the first set of conditions corresponding to a first visual reference viewed by a patient through a first combination of the plurality of lenses and the first plurality of response fields configured to receive first feedback from the patient indicative of the patient's vision under the first set of conditions;
• receive a first input indicative of the patient's vision under the first set of conditions;
• automatically display, based on the first input, an updated first visual reference viewed by the patient;
• iteratively update, based on the first input, a second combination of the plurality of lenses and maintain the first plurality of response fields and receive feedback from the patient until a predefined number of responses are received during the first test to determine an endpoint for the first test;
• automatically generate and display, based on the determined endpoint for the first test, a second set of conditions for a second test and a second plurality of response fields, the second set of conditions comprising a second visual reference viewed by the patient and a third combination of the plurality of lenses, and the second plurality of response fields configured to receive second feedback indicative of the patient's vision under the second set of conditions;
• receive an updated input indicative of the patient's vision under the second set of conditions;
• and
• determine an endpoint for the second test based on a determined a visual acuity during the second test matching a predefined visual acuity value.
