Screen filters for Visual Snow Syndrome modulate visual cortex neural processing by reducing high-contrast luminance and chromatic stimuli, potentially mitigating aberrant neural hyperexcitability. These filters aim to decrease visual noise and sensory overload by attenuating specific wavelengths and light intensities that may trigger or exacerbate visual perception disturbances. Their mechanism involves selectively filtering visual input to minimize cortical hyperactivation and normalize sensory signal processing.
