Why OPTOVERA
Most systems try to predict whether someone is ready.
OPTOVERA measures worker state directly — before work begins.
A worker can appear ready for duty — and believe they are ready — while their actual state tells a different story.
The gap between appearance and reality is where incidents happen.
Today’s approaches rely on indirect signals — behavior, trends, or visible signs. They estimate readiness.
But they do not measure worker state at the moment decisions are made.
Four requirements. One standard.
What a reliable state measurement must be
Tamper-resistant
The signal cannot be influenced, masked, or consciously controlled. It must come directly from the body — independent of effort or cooperation.
Immediate
Safety decisions happen now.
The measurement must reflect worker state at the point of work — not trends over time.
Preventive
Detection after performance is affected is not prevention. A reliable system must identify state risk before the shift begins.
Non-intrusive
If it disrupts operations, it won’t be used consistently. Consistency is the only way measurement creates value.
Why Other Approaches Fall Short
Wearables
Vehicle Camera
PVT

Psychomotor Vigilance Test (PVT)
The flaw: it measures effort, not worker state.
PVT tests performance under effort.
A worker who is engaged and trying can perform adequately — even if their underlying state is degraded.
A worker who is distracted or uncooperative can underperform — even if their state is not compromised.
PVT measures what someone can do when trying. It does not measure their actual state.
Wearables
The flaw: they track trends, not current state.
Wearables monitor heart rate, oxygen saturation, skin temperature, and similar signals over time. These signals are indirect and influenced by context, variability, and individual differences.
Wearables tell you how someone has been. They cannot tell you the state they are in right now.
Vehicle and Workplace Cameras
The flaw: they are reactive, not preventive.
Camera-based systems analyze facial features, eye closure, and head position to detect visible signs after worker state has already degraded. They are sophisticated. They are also too late.
By the time a camera detects a visible change, performance has already been affected.
Detection at that point is too late. Prevention requires knowing before the shift begins.
Why OPTOVERA Is Different
Where other approaches estimate,
OPTOVERA measures.
OPTOVERA Scan uses Pupillary Light Reflex (PLR) — an involuntary neurological response regulated by the autonomic nervous system.
-
It cannot be consciously influenced.
-
It cannot be masked by effort or behavior.
-
It reflects the actual state of the nervous system at the moment of measurement.
The result is an objective, tamper-resistant, cause-agnostic measure of worker state — available in one minute, at the point of work, before the shift begins.
-
Not a proxy.
-
Not a trend.
-
Not a reaction after performance declines.
A direct measurement of worker state — when it matters most.
