Facts About Visual Snow


Visual Snow is a devastating neurological condition that can affect an individual’s vision, hearing, and cognitive functioning. Most often, the condition causes a person to process visual information abnormally, making normal life more difficult.

The cause of Visual Snow Syndrome is unknown and diagnosis of Visual Snow is difficult because eye examination results show normal results. There is not yet an evidence-based treatment or current cure for Visual Snow.
