About Visual Snow Syndrome
The underlying cause of visual snow syndrome remains unclear, but it is believed to be due to a problem with how your brain processes visual images. The flickering tiny dots associated with the condition are typically black and white, but they can be flashing, colored, or even transparent. Most people with visual snow syndrome see these tiny dots in both eyes all the time. Your symptoms may seem to worsen after long periods of looking at a screen or during times of high stress.
