What is eyecheck l.jpg
What is EyeCheck?

  • EyeCheck™ Pupillometer

    • Analyses Eye Pupil Response

    • Employing simple medical principles

    • Straightforward measurement techniques

    • Rapid, two minute test…...

  • Application to:

    • Measurement of fatigue

    • Detection of drugs.

What is EyeCheck?

EyeCheck:

  • Non-invasive

  • Non-Gender specific

  • Instant results and analysis

  • Eliminates privacy issues

  • No baseline necessary

  • Medically peer reviewed

  • Easy-to-use, minimal training required

Why test l.jpg
Why Test?

Fatigue:

  • Occupational Hazard

  • Rarely monitored, subjective

  • Accidents, poor decision making

  • Disfunctional behaviour, stress, irritation

  • Major risk in many responsible professions:

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

    • Especially where “Sleep Hygiene” is poor

Advanced Aviation Technology

Why test7 l.jpg
Why Test?

Fatigue due to:

  • Lack of sleep

  • Disrupted sleep patterns

  • Stress, overwork, Illness…..

    17-19 hrs without sleep - Equivalent to 0.05 BAC

[Williamson AM, FeyerA-M. 2000. “Moderate sleep deprivation produces impairments in cognitive and motor performance

equivalent to legally prescribed levels of alcohol intoxication.” Occupational and Environmental Medicine57:649-55. Dawson, D. and K. Reid. 1997. “Fatigue, Alcohol and Performance Impairment.” Nature388 (July 17): 235.]

Application areas l.jpg
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)

Application areas9 l.jpg
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

How does it work l.jpg
How Does it Work?

  • 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)

How does it work11 l.jpg
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

Underlying technology13 l.jpg
Underlying Technology

  • Able to take other measurements:

    • “Fatigue waves”

    • Oscillation of the pupil over 15 minutes

    • Detailed performance of pupil over time

  • Supports studies of human performance

    • Impact of sleep patterns on fatigue

    • Baseline task performance against fatigue

    • Sleep hygiene
