Penlight
Not quantifiable.
Quantitative pupillometry
Stop guessing.
Start measuring.
Outside the hospital, pupil assessment still means a penlight and an opinion — and studies show 30% or more of abnormalities are missed. LIOR™ is a pocket-sized digital pupilometer that measures pupil size and reactivity in seconds: objective neurological data, wherever the patient is.

Our mission
Objective answers,
from the first assessment.
The pupil is one of the most direct windows into neurological status. Outside the ICU, assessing it has always been subjective: a penlight, a guess, and a note in a chart.
Defibrillators, pulse oximeters, and ultrasound all moved from hospital-only to field-ready to indispensable. Objective pupillometry is on that path now — and LIOR is the device built to take it there.

Applications
Frontline. Institutional. Consumer.
Clinical credibility first, then broader institutional use, then personal wellness at home.
Phase 1
Frontline
Paramedic services, emergency and trauma care, critical care transport, and military field medicine.
- Critical Care TransportObjective pupil measurement during air and ground transport.
- Paramedic ServicesFast, objective pupil assessment at the point of care.
- Emergency & Trauma CareQuantifiable pupil measurements to support assessment and documentation.
- Remote & Rural CarePortable pupillometry where access to hospital based equipment is limited.
- Military & Field MedicineObjective pupil assessment in mobile and austere care environments.
Phase 2
Institutional
Hospitals, schools, sports, workplace health and safety, medical training, and assisted living.
- Schools & UniversitiesA future tool for standardized pupil assessment and documentation.
- Sports & AthleticsObjective pupil measurement to support established assessment protocols.
- Workplace Health & SafetyPortable objective measurement for occupational health settings.
- Hospitals & Health SystemsObjective pupil measurement across appropriate clinical settings.
- Medical Training & SimulationA measurable standard for teaching and practicing pupil assessment.
Phase 3
Consumer
Home monitoring, family health, personal baselines, caregiver support, and remote care.
- Home MonitoringObjective pupil measurements from home.
- Family HealthA simple way to capture and track pupil measurements over time.
- Personal BaselinesCreate a personal reference point for future comparison.
- Caregiver SupportSimple objective measurements for people being cared for at home.
- Remote CareFuture use alongside remote and virtual healthcare services.
The difference
Built without compromise.
Penlights are simple but not quantifiable. ICU units are objective but expensive and not built for the field. Phone apps rely on personal devices and do not fit naturally into medical workflows.
LIOR brings those strengths together in an affordable, field-built device, powered by our patent pending distance independent measurement approach.
