What Is Visual Snow

Visual snow or visual static is transitory or persisting visual symptom where people see snow or television-like static in parts or the whole of their visual fields, constantly in all light conditions even visible in day-light. The severity or density of the "snow" differs from one person to the next; in some circumstances, it can inhibit a person's daily life, making it difficult to read, drive, perform routine tasks, see in detail (even in bright daylight) or focus correctly because of afterimages and other visual and non-visual symptoms.

Little is known about this rare condition, and it has conventionally been regarded as a variant of migraine aura—though recent research shows this is not the case. Visual snow is now regarded as a unique syndrome—usually presenting with other symptoms, such as persistent afterimages, photophobia, enhanced blue field entoptic phenomenon and tinnitus.


Newly published research has confirmed a “brain dysfunction in patients with visual snow”, located principally in the right lingual gyrus. Before this, no other etiology for visual snow had been identified. Insofar as sufferers of visual snow had undergone ophthalmic, neurological and psychiatric examinations, no systematic problems besides the visual snow were found. The recent research that indicates this disorder occurs in the brain has important ramifications for the possibility of potential treatment. However, standard treatment protocols have yet to be established.

Wether you suffer from this condition or not, donating to this cause would be essential to those who are afflicted by these symptoms. Visual Snow includes Static Vision, Many Eye Floaters, Ghosting After-Images, Enhanced Glare, Halos, Starburts, Loss of Contrast, and often times Blurred Vision.

Visual Snow can also be accompanied by Tinnitus, Hyperacusis, Palinopsia, Entoptic Phenomena, Photophobia, Nyctalopia, Closed-Eye Hallucinations, Derealization, Vertigo, and Abberations and Pupil Size, along with Migraine Auras. 


The Eye On Vision Foundation needs to raise $75,000 for the next phase of visual snow research.
Visual Snow syndrome is a rare neurological condition, which causes patients constant untreatable visual disturbances. These disturbances include, but are not limited to, static across the entire visual field, floaters, after images, light sensitivity, ghosting, trails, double vision, night blindess, flashes, and blue field entopic phenomenon.

The syndrome also causes other physical symptoms in patients including dizziness, tinnitus, migraines, numbness, tingling, head and ear pressure, vertigo, fatigue, depersonalization and several others.
Prof. Peter Goadsby and Dr. Christoph Schankin have begun research into visual snow, but the funding has run out, and more money is needed to continue this crucial research.

The Eye on Vision Foundation is also supporting ground-breaking research into eye floaters. Our goal is to raise a minimum of $50,000 per year for eye floaters research.
Currently there is no research being conducted to find a non-surgical treatment for eye floaters. We are trying to change that! Help make a difference in the sight and lives of many people suffering from impaired vision due to vitreous eye floaters!
