what is eyecheck
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
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

why test7
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.]

how does it work
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
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
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
