Visual Snow Syndrome affects people of all ages and backgrounds around the world, with no sex prevalence.
Among patients with Visual Snow Syndrome, males and females are equally represented.
Before 2019, it took an average of up to 9 years for an individual with Visual Snow Syndrome to receive an accurate diagnosis (due to the lack of awareness amongst the majority medical professionals).
For those who experienced the onset of Visual Snow Syndrome during childhood, symptoms started on average at 12.8 years old, with the youngest cases of developing Visual Snow Syndrome being at around 8-9 years old.
Since Sierra Domb founded Visual Snow Initiative in 2018, the number of research and publications for Visual Snow Syndrome has quadrupled.
Chromatic filters reduced palinopsia and photosensitivity by 50% on average.
