Visual Snow Syndrome (VSS) is a neurological condition that causes people to see what appears like static or "visual noise" across their entire visual field—similar to the grainy fuzz of an untuned TV. This static is present even with closed eyes and is often accompanied by other visual disturbances, including afterimages, light sensitivity (photophobia), trailing images (palinopsia), and difficulties in low-light conditions.

One of the most promising symptom-management tools for VSS is precision-tinted lenses, often referred to as therapeutic or specialty tints. These lenses are designed to filter out certain wavelengths of light that may trigger or worsen visual disturbances.
