Blue field entoptic phenomenon has the appearance of tiny bright dots moving rapidly along squiggly lines in the visual field. It is much more noticeable when viewed against a field of pure blue light and is caused by white blood cells moving in the capillaries in front of the retina.
Likewise, why do I sometimes see tiny moving black dots? Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina. The shadows you see are called floaters.
Beside above, does Visual snow get worse over time?
The symptoms of visual snow syndrome can change over time, with some people noticing an improvement of symptoms (with or without treatment) and some people noticing that their symptoms worsen. However, many find even a lessening of the symptoms can greatly increase their quality of life.
Is visual snow dangerous?
Visual snow syndrome is a rare disease that involves both eyes and the entire field of vision. Visual snow is like seeing static, such as looking at a bad picture on an old television set. It can be an extremely debilitating disease that can vastly impact quality of life and make daily life tasks difficult.
