What is EyeCheck?

  • EyeCheck™ Pupillometer

    • Analyses Eye Pupil Response

    • Employs simple medical principles

    • Straightforward measurement techniques

    • Rapid, two minute procedure…..

  • Application to:

    • Measurement of fatigue

    • Detection of drugs

What is EyeCheck?

What is EyeCheck?

An easy to use binocular-like device:

  • Non-invasive

  • Non-Gender specific

  • Instant results and analysis

  • Eliminates privacy issues

  • No baseline necessary

  • Medically peer reviewed

  • Easy-to-use, minimal training required

Advanced Aviation Technology

How Does it Work?

  • The eye is allowed to adapt to dark (30 secs)

    • EyeCheck measures initial pupil diameter

  • A brief flash of light:

    • measures reflex amplitude, rate of constriction

    • final minimum pupil diameter, time to min. dia.

  • EyeCheck measures real-time eye dynamics

    • infrared optics, collects IR light scattered by eye

    • 10-2 mm accuracy, 10 samples per second

Normal Pupil Response

Three normal responses (red, blue and green)

Advanced Aviation Technology

Fatigue at 12 Hours

Red is unfatigued, blue and green are at 12 hours

Advanced Aviation Technology

Fatigue at 18 hours

Red is unfatigued, blue and green are at 18 hours

Advanced Aviation Technology

Fatigue at 22 hours

Red is unfatigued, blue and green are at 22 hours

Advanced Aviation Technology

Application Areas

  • Measuring fatigue

  • Fatigue and human performance

  • Impact of duty times, shift patterns

  • Safety monitoring of personnel

  • Sleep hygiene, stress

  • Detection of drugs (pre-screening)

Advanced Aviation Technology

Application Areas

  • Roads, Trains, Boats, Planes

    • Pilots, cabin crew, maintenance, ATC, drivers

    • On duty, in transit, on standby

    • Airlines, airports, rail, maritime, road transport

    • Police, private security

    • Public safety, clubs

    • Research

Why Test for Fatigue?

Fatigue rarely monitored, despite impact on:

  • Known Occupational Hazards

    • Accident rates, poor decision-making

    • Disfunctional behaviour, stress, irritation

  • Major risk in many professions:

    • Pilots, ATC, Doctors, Police, Security etc. etc.

    • Especially as “Sleep Hygiene” is often poor

      Note: 17-19 hrs without sleep equivalent to 0.05 BAC

Causes of Fatigue

  • Causes of fatigue can be complex

    • Onset of fatigue may be due to several factors

  • Fatigue can be caused by:

    • Lack of sleep

    • Poor personal sleep hygiene

    • Disrupted sleep patterns

    • Stress, Overwork, Illness…..

Summary

  • Easy to use…

  • Simply look into the unit:

  • A light flashes, the pupil reacts to stimuli, causing constriction followed by re-dilation.

  • EyeCheck measures, records and evaluates this response….. (include subject data, age)

Summary

  • Minimal Training required

  • Rapid, Accurate, Reliable, Adaptable

  • Benchmarks Fatigue, Duty Time Schemes

  • Whole workforce testing possible

  • Performance improvement

  • Fitness-for-duty testing

Advanced Aviation Technology

Summary

  • Non-invasive

  • Lightweight, portable, user friendly

  • Can sample large numbers quickly

  • Interfaces to PC, Laptop, PDA

  • Records & analyses subject data, results

  • S/W analysis programs supplied

  • “Breathalyzer” for fatigue impairment

Benefits of Screening

  • Enhances operating environment

  • Improves reliability, performance, productivity

  • Reduces incidents, accidents, risk

  • Reduces loss, reduces costs

  • Improves morale

  • Strong deterrence for substance abuse
