VCS testing involves the presentation of a series of images of decreasing contrast to the patient, and the recording of the contrast levels where patterns, shapes, or objects can or cannot be identified.
The ability to detect contrast is part of the brain’s function. Contrast is your ability to discern black from white, and also between different shades of gray. Toxins affect nerves, and we can measure is the optic nerve by checking its ability to see finer and finer degrees of contrast. Toxins reduce blood flow to the nerves, effectively decreasing oxygen. In later stages; it can cause blurred vision and other functional problems. While the VCS test is not diagnostic, it does give us an idea of what might be important in your treatment, and also gives us a point of reference for future improvement.
