Optalert
Scientifically validated drowsiness detection for mining equipment operators using blepharometry.
About Optalert
Optalert is a Melbourne-based medical technology company that pioneered the use of blepharometry — measurement of eyelid blink velocity — to objectively detect and measure drowsiness in real time. Founded by sleep medicine clinician Dr. Murray Johns, the company developed the Johns Drowsiness Scale (JDS), the only scientifically validated objective measurement of drowsiness, validated by over 130 peer-reviewed publications and deemed commensurate with gold standard laboratory measures by Harvard Medical School.
In mining, Optalert is the established wearable drowsiness detection device commercially validated at scale by Vale (one of the world's largest mining companies), BHP, and Shougang Hierro Peru. The company reports 15+ consecutive years with no major accident at any mine site where its technology is operational, a 95% reduction in drowsiness-related risk, and a 5% increase in production at a large Brazilian iron ore mine after implementation. The technology measures eyelid movement velocity 500 times per second using infrared LEDs embedded in specialised glasses.

by Optalert
A ruggedised in-cab drowsiness detection system comprising Optalert's specialised glasses (wired or wireless) paired with a rugged Android tablet. The system provides continuous real-time JDS drowsiness scores displayed in-cab with audio and visual alerts at medium and high risk levels. Data transmits via 3G or Wi-Fi to the cloud-based IRIS dashboard for remote fleet monitoring by supervisors. Designed for extreme mining conditions with an operating range of -21°C to 60°C.
Eagle Insights
by Optalert
A cloud-based AI analytics platform providing longer-term data analytics to predict and reduce systemic drowsiness risk across mining operations. Features include the real-time IRIS fleet dashboard, SMS and email alerts, and comprehensive reporting at driver, site, and organisational levels. Helps mining organisations quantify the impact of drowsiness from individual operator through to senior management, enabling data-driven fatigue policy decisions.
Eagle Light
by Optalert
A compact, small form-factor drowsiness detection device designed for light vehicles — 4WDs, dual-cabs, and small commercial vehicles used by mine supervisors and field personnel. Based on a rugged handheld device, it automatically starts and shuts down with vehicle ignition and pairs via Bluetooth with Optalert wireless glasses.
