Oculomotor Neurological Assessment

Your eyes reveal what your brain
is doing right now.

Slip on a pair of specialized diagnostic glasses — comfortable, lightweight, familiar as any eyewear you've worn. In five minutes, without a single needle, blood draw, or complicated procedure, ClearGazeTest measures twelve neurological biomarkers with clinical precision. The result is an objective picture of how your brain and nervous system are functioning. No guesswork. No symptom checklists. Just clarity.

How It Works

As easy as trying on a new pair of glasses.

ClearGazeTest uses lightweight diagnostic glasses — similar in form to today's advanced vision eyewear — with precision infrared optics built inside. There's no discomfort, no preparation, and nothing to fear. You simply wear them, follow a few gentle visual prompts, and the system does the rest.

  1. 1
    Put on the glasses Sleek, lightweight diagnostic glasses — comfortable from the moment you put them on. Think of the elegant simplicity of Apple Vision Pro or Varjo precision optics. Two tiny infrared cameras inside capture both eyes simultaneously.
  2. 2
    Follow gentle visual prompts Small visual targets appear inside the lenses — like soft points of light. You follow them naturally. No buttons to press, no tasks to complete, no effort required beyond simply looking.
  3. 3
    Your eyes tell the full story In five minutes, both eyes are captured at 500 frames per second. Every saccade, every pupil response, every convergence movement — recorded and analyzed automatically with mathematical precision.
  4. 4
    A clear answer, immediately A scored clinical report shows whether each of twelve neurological functions falls within normal range. Objective data. No interpretation left to chance. Your clinician has the information they need to help you.

Who This Is For

Real situations. Real people. Real answers.

ClearGazeTest was built for the moments when a symptom checklist isn't enough — when you need to know, not guess.

My twelve-year-old took a hit at soccer practice on a Thursday. By Saturday she seemed fine. But I wasn't sure. ClearGazeTest showed her brain wasn't quite ready — and saved her from getting back on the field too soon.

I've been told my memory problems were just stress, just aging, just anxiety. For three years. ClearGazeTest picked up something in my eye movements that changed the conversation with my neurologist entirely.

Twenty years of service. Three deployments. I got a TBI diagnosis once, cleared the next physical. ClearGazeTest was the first test that gave me a number — something I could show my VA doctor — instead of just my story.

The Twelve Biomarkers

What your eyes are telling us, and what it means.

Every one of these measurements has been documented in peer-reviewed literature as a sensitive indicator of neurological health. Together, they form a complete picture that no single test — and no symptom questionnaire — can provide.

These are not experimental measures. They are the same functions a neurologist evaluates when they shine a light in your eye, ask you to follow their finger, and watch how your eyes move. ClearGazeTest performs that entire examination automatically, quantifies every result precisely, and produces a documented clinical record — in five minutes.

Saccadic AccuracyHow precisely the eyes land where they aim
Smooth PursuitHow smoothly the eyes track a moving object

The Science

Seventy-five years of neuro-ophthalmic science.
Now available where you need it.

ClearGazeTest is built on the foundational work of Dr. David G. Cogan, MD — the physician who established neuro-ophthalmology as a medical subspecialty and spent his career at the National Eye Institute documenting how every major neurological disease leaves a measurable signature in eye movement.

"Virtually every neurological disease produces a measurable signature in eye movement. The eye is the window into the nervous system." — Grounded in the foundational taxonomy of Dr. David G. Cogan, MD, National Eye Institute, NIH. The ClearGazeTest battery measures the twelve oculomotor functions Dr. Cogan identified as neurological biomarkers.

Established Science, Not Experimental

The twelve oculomotor biomarkers measured by ClearGazeTest are documented in hundreds of peer-reviewed publications spanning seven decades. This is not a new idea — it is validated neuroscience that has never before been portable or accessible outside a research laboratory.

Objective by Design

Symptom checklists and cognitive tests can be minimized, faked, or distorted by fear, pride, or poor memory. Eye movements cannot. The oculomotor system reflects the state of the nervous system directly — beyond the reach of conscious effort or patient motivation.

At the Point of Care, Finally

Until now, this level of neurological assessment required a $40,000 laboratory, a trained technician, and a controlled clinical environment. ClearGazeTest brings the same precision to any clinical setting — and to the places neurological injury actually happens.
