What a VCS Score Can (and Can't) Tell You About Mold Recovery

A VCS score can change. The real question is what that change actually means for you.

Visual contrast sensitivity is a real phenomenon, and some studies show it can shift with treatment and with certain exposures. But the published evidence hasn't established serial VCS testing as a clear, reliable measure of mold recovery, especially when so many other things can affect contrast sensitivity too: sleep, eye strain, even how tired you are the day you take it.

That's the pattern with a lot of the tests marketed around mold recovery. A number can move, and it's tempting to read movement as proof, but a test that's sensitive to lots of different things isn't the same as a test that's specific to mold. Something can shift for reasons that have nothing to do with whether you're actually getting better.

What I focus on instead

Rather than leaning on a single score to tell the story, I focus on the information that actually helps guide treatment and next steps: your exposure history, whether your symptoms track with being in or away from a particular building, and the broader pattern across your gut, hormones, sinuses, and energy.

If you're trying to figure out whether a water-damaged building is part of what's going on, the more useful starting point is usually simpler than another test. Look for exposure clues: a history of a damp building, symptoms that ease when you travel or spend time away, a room or building that reliably makes you feel worse. Then look at the whole pattern of what your body's been dealing with, because it's rarely just one thing.
