SAFETY - DROWSINESS MEASURING GLASSES
Fatigue monitoring can save lives
Optalert drowsiness monitoring glasses work by measuring a driver’s eyelid movements 500 times a second using a small LED built into the frame of the glasses.
Key measurements track how fast and how far the eyelid opens and closes. The measurements are translated into a score, which the driver sees inside the cab, on the Optalert Dashboard Indicator.
The lightweight frame of Optalert glasses is said to provide comfortable all-day wear, with an interchangeable lenses to suit day and night driving.
The scratch-resistant, polycarbonate lenses come in five colours, with UV protection that is said to comply with Australian and New Zealand Standards.
There is also a prescription lens adaptor for those who wear prescription glasses when driving.
All Optalert glasses are custom made to suit face shape and nose bridge.
