University of California, San Diego (UCSD) researchers have enabled screening for neurological diseases through an eye-scanning smartphone application. The app employs the near-infrared camera built into many newer smartphones in combination with a conventional selfie camera to measure changes in the pupil's diameter, which could be used to evaluate a person's cognitive condition. The infrared camera allows the app to estimate pupil size with sub-millimeter accuracy across various eye colors, while the selfie camera records the stereoscopic distance between smartphone and user. Said UCSD's Colin Berry, “We hope that this opens the door to novel explorations of using smartphones to detect and monitor potential health problems earlier on.” .. .
