1. A method for adjusting flash intensity based on retinal pigmentation, the method comprising:
determining a retinal pigmentation of a retina of an eye positioned at an imaging device by:
commanding the imaging device to obtain feedback by flashing an infrared signal at the retina;
receiving the feedback from the imaging device, the feedback indicative of absorption of the infrared signal by the retina; and
determining the retinal pigmentation of the eye based on the feedback;
commanding the imaging device to adjust an intensity of a flash component from a first intensity to a second intensity based on the retinal pigmentation;
commanding the imaging device to capture an image that is illuminated by the flash component at the second intensity; and
receiving the image from the imaging device.
