Test for signs of issues with your sleep in minutes.
It's easy. Count the diamonds that appear and immediately get a result.
Perform a test for issues with your sleep in minutes.
The Owl Eye test is super simple. First, you go somewhere quiet with good lighting. When the test begins, a circle appears on the screen and every few seconds it flickers to either a diamond or square. You simply count the number of diamonds that appear. After a few minutes, the app shows if it detects signs of sleep issues and suggests next steps.
In the background, Optalert’s ingenious algorithm is processing your every eyelid movement – every blink, every micro-flutter. It then detects the subtle impairment that arises from breathing issues during sleep. The video itself is discarded and only your head and eye data is retained. This builds on Optalert’s world-renowned biomarker, the Johns Drowsiness Scale, that detects drowsiness and is used in sleep laboratories around the world.
The Owl Eye app was created by leading medical technology innovator Optalert. The underlying technology is based on data collected from leading sleep laboratories at Monash Medical Centre, the Monash Biomedicine Discovery Institute, and the Institute for Breathing and Sleep (IBAS).
