Device-assisted eye imaging and/or measurement

An imaging and/or measuring apparatus comprising:

• at least one light source, the at least one light source comprising a plurality of light sources configured to illuminate respective portions of a subject's eye, the plurality of light sources comprising a first light source configured to illuminate a first portion of the subject's eye and a second light source configured to illuminate a second portion of the subject's eye different from the first portion of the subject's eye;
• at least one imaging and/or measuring sensor;
• and
• at least one processor coupled to the at least one light source and the at least one imaging and/or measuring sensor and configured to:
• transmit instructions to the at least one light source configured to cause the at least one light source to illuminate a plurality of portions of the subject's eye;
• determine a location of a first portion of the subject's eye based on the illumination of the plurality of the portions of the subject's eye;
• after determining the location of the first portion of the subject's eye, select a subset of the plurality of light sources based on the determined location of the first portion of the subject's eye, the selecting comprising:
• including the first light source in the subset of the plurality of light sources based on (i) the determined location of the first portion of the subject's eye and (ii) the configuration of the first light source;
• and
• excluding the second light source from the subset of the plurality of light sources based on (i) the determined location of the first portion of the subject's eye and (ii) the configuration of the second light source;
• after selecting the subset of the plurality of light sources, transmit instructions to the at least one light source configured to cause an adjustment of the at least one light source to selectively illuminate the first portion of the subject's eye with illumination light by turning on the selected subset of the plurality of light sources;
• and
• transmit instructions to the at least one imaging and/or measuring sensor configured to cause the at least one imaging and/or measuring sensor to capture an image and/or measurement of the first portion of the subject's eye while the at least one light source selectively illuminates the first portion of the subject's eye.
