1. A module for use with a mobile device to measure an aberration of a patient's eye, the module comprising:
a light shaft having a proximal end and a distal end, the light shaft comprising a first plurality of optical components arranged to direct light along a first light path from the distal end to the proximal end, and a second plurality of optical components arranged to direct light along a second light path from the proximal end to the distal end, wherein at least a portion of the first and second light paths are coextensive; a light source; and a connector located at the distal end of the light shaft, the connector comprising at least one guide component for positioning the distal end of the light shaft adjacent a light detector of the mobile device, wherein, when the distal end of the light shaft is positioned adjacent to the light detector of the mobile device;
the first plurality of optical components directs light from the light source along the first light path to the proximal end of the light shaft, andthe second plurality of optical components directs light along the second light path from the distal end of the light shaft to the light detector of the mobile device. |
