Abstract
A camera system on mobile device for automatic eccentric photorefraction to measure potential refraction errors in the human eye. A mobile device such as a smartphone has one or more lenses and one or more illuminators which are used to create, capture, and measure red eye reflexes. The red eye reflex measurements are then used with a machine learning algorithm to determine if refractory error is present in the eye.
