1. An apparatus to measure relative refractive properties of an eye, comprising:
one or more light sources configured to emit a light;
projection optics arranged to project the light emitted by the one or more light sources onto a foveal location of a retina and a non-foveal location of the retina;
imaging optics arranged to generate a plurality of images from the light projected onto the foveal location of the retina and the non-foveal location of the retina;
an imaging device configured to capture the plurality of images from the imaging optics; and
a processor coupled to the imaging device, the processor configured to determine refractive properties of the eye for the foveal location of the retina and the non-foveal location of the retina;
wherein the eye comprises a pupil and wherein the light to the foveal location of the retina travels through the pupil at a first angle and the light to the non-foveal location of the retina travels through the pupil at a second angle different from the first angle and wherein the refractive properties of the eye for the foveal location of the retina correspond to the light traveling to the foveal location through the pupil at the first angle and the refractive properties of the eye for the non-foveal location of the retina correspond to the light traveling through the pupil at the second angle.
