Vision screening device including color imaging

Abstract

A vision screening device for administering vision screening tests to a patient, to determine the presence of diseases and/or abnormalities in the eye(s) of the patient, is described herein. The vision screening device may include associated methods and systems configured to perform the operations of the vision screening tests. The device may include a radiation source configured to generate near-infrared (NIR) radiation, a sensor configured to capture a grayscale image representing the radiation reflected by the eye(s) of the patient, a white light source, and a camera configured to capture a color image of the eye of the patient. The device may also be configured to generate a composite image based on the grayscale image and/or the color image, determine a difference between a value associated with the eye and an expected value, and generate an output indicative of a condition associated with the eye(s) based on the difference.
