It works

More than 20 years of research has gone into Optalert’s drowsiness detection technology. This is why it works.

Optalert’s early-warning drowsiness detection system is designed to detect the early signs of drowsiness. As such, it is capable of objectively detecting drowsiness even before we are aware that we are feeling tired.

Developed through more than 20 years of research into the physiology of drowsiness, Optalert’s drowsiness detection system incorporates the only scientifically validated technology continuously and unobtrusively measuring a person’s alertness.

It is also the only system in the world that can provide a real-time drowsiness score. No more guessing on the fatigue levels of your fleet. Now you know, when and who is at risk of a drowsiness-related incident.

Optalert’s glasses

Optalert technology uses a system of infrared (IR) reflectance oculography housed in a pair of glasses that can monitor the eye and eyelid movements of drivers.

This continuous measurement does not interfere with their performance of the driving task.

Optalert’s technology has enabled several ocular variables to be identified that can be used in combination to quantify drowsiness on the Johns Drowsiness Scale (JDS™).

The Johns Drowsiness Scale (JDS™)

The JDS™ does not require adjustment for individuals. It is these early physiological changes in blinks, particularly the relative velocities of the eyelid closure and re-opening phase of blinks, which characterise the drowsy state.
