Illinois State Troopers will soon be equipped with a new device called EYECHECK.PMD (Pupil Measurement Device), an instrument used to evaluate fatigue-related and drug/alcohol-related impairment of drivers. EYECHECK is a binocular, battery-operated instrument that weighs approximately 14 oz (0.4 kg). When a person peers into the instrument's viewing area, a light flashes to stimulate the pupils before measuring the pupillary response. The instrument's internal software analyzes the data, displays the results on a light-emitting diode (LED) screen and determines the level of fatigue. The device is designed to indicate presence of alcohol, cocaine, marijuana, inhalants, stimulants, and depressants. It is a noninvasive device that can presumptively indicate the presence of, and differentiate between, alcohol, drugs, inhalants, and fatigue of the driver. EYECHECK will not be used as an evidential device in court, but as a pre-arrest screening device.
