1. An impairment analysis system comprising:
a handheld image capture device that captures a plurality of images of an eye of a subject illuminated by ambient light over a period of time;
a computing device comprising at least one processor and memory configured to:
control a light source to emit light in a predetermined pattern for guiding the subject's eyes during capture of the plurality of images of the eye over the period of time;
receive, from the image capture device, the captured plurality of images, wherein the images include pixels corresponding to a pupil, iris, background, or other features of the eye of the subject;
maintain a database of machine learning analysis of other subject's normal eye movement in response to an applied light stimulus;
classify pixels from the captured plurality of images as either pupil, iris, background, or other features of the eye of the subject based on the database of machine learning analysis;
track movement of the classified pixels in the plurality of images over the period of time;
analyze impairment of the subject based on the tracked movement as compared to the machine learning analysis in the database; and
present, to a user, a result of the impairment analysis.
