Relieving Symptoms of Visual Snow

Visual snow refers to the constant perception of visual static. Research shows that prolonged exposure to a stimulus can ‘quiet’ the visual system’s response to what follows (Montoya et al., 2023). 

This has led to the theory that visual noise itself might help counteract visual snow.

"Montoya et al. created a very intense high-contrast version of visual noise, presented it to patients, and recorded responses. In most cases, adaptation to the dynamic noise temporarily reduced the snow, often rendering it invisible.” (Linda Seminara Via Journal Highlights)

Online responses highlight the strong potential of adaptation in reducing visual snow, positioning this approach as a valuable tool for diagnostic testing and uncovering its neural origins. However, the Visual Snow Initiative cautions that this method is not universally effective, as some individuals show no response to visual noise. 

Below features a YouTube video by Simon D. Fleming showing a continuous moving pattern that has provided temporary relief for some people with visual snow.
