Dr. Shoemaker Visual Contrast Test

If you're worried that you've been exposed to mold, you can get clear answers in minutes with the Shoemaker Protocol Visual Contrast Sensitivity Test.

You're experiencing strange symptoms; fatigue, headaches, brain fog, and you're wondering if mold is to blame. But you're stuck. Most doctors don’t recognize mold illness. Lab tests are expensive. And you need clarity now... not weeks from now. The Shoemaker Protocol Visual Contrast Sensitivity Test is a trusted screening tool that detects possible biotoxin exposure... right from your device, in minutes. 

The VCS test is a measure of one the neurologic functions of vision known as “contrast.” Biotoxins impair the ability to detect subtle contrast within 24-36 hours after exposure. The Shoemaker Protocol™ VCS testing system is an extremely valuable tool to detect and monitor exposure to toxic environments for individuals with CIRS. 

The VCS test has 92% accuracy rate based on data collected from tens of thousands of tests taken over the years since Dr. Shoemaker first began using it. Your score is recorded and determined according to published criteria.

For the vast majority of the population, when the instructions are accurately followed, the test results have proven to be consistently reliable.

What is a visual contrast test?

Think of it like an eye test... but for your brain.

Instead of checking how sharp your vision is, the VCS test checks how well your visual system (including your optic nerve and brain) can detect contrast — light vs. dark. This is a powerful early indicator of issues affecting the nervous system, like mold or biotoxin exposure.

How It Works: Much like a hearing test plays tones at lower and lower volumes, the VCS test shows a series of patterned images with decreasing contrast — patterns get harder to see as the test progresses. Your responses help determine your contrast sensitivity threshold.

Why It Matters: Exposure to mold and biotoxins can impair how your brain processes visual information — even if your eyesight seems “normal.” That’s why VCS is a valuable screening tool for Chronic Inflammatory Response Syndrome (CIRS), Lyme disease, and other biotoxin-related illnesses.

Does the shoemaker protocol work?

Yes! And it’s the only treatment protocol with peer-reviewed evidence to prove it.

“The only treatment in the published literature documenting clinical efficacy for Chronic Inflammatory Response Syndrome (CIRS) is the Shoemaker Protocol.”

Developed by Dr. Ritchie Shoemaker and refined over two decades of clinical practice and research, the protocol is a step-by-step medical framework that addresses the underlying inflammatory response caused by biotoxins like mold, Lyme, and more.

Why It’s Trusted:

• Backed by peer-reviewed studies and outcome data
• Used by certified practitioners and clinics worldwide
• Built on measurable biomarkers, including visual contrast sensitivity
• Continuously updated based on emerging research

Patients using the protocol report:

• Improved cognition, energy, and mood
• Reduction in inflammation and symptom clusters
• A clearer path to recovery when nothing else worked

The only treatment in the published literature documenting clinical efficacy for the treatment of Chronic Inflammatory Response Syndrome is the Shoemaker Protocol.

How accurate is the VCS test?

Extremely. According to Dr. Shoemaker, if symptoms are present and the VCS test is positive — even in one eye — there’s a 98.5% chance the person has CIRS.

That makes the Visual Contrast Sensitivity (VCS) Test one of the most accurate screening tools in medicine for detecting mold-related biotoxin illness.

✅ It’s simple
✅ It’s fast
✅ It works — with 98.5% predictive accuracy when symptoms and results align
