• Well these little flashes of light are known as Blue Field Entoptic Phenomenon. This disorder is also called “Scheerer's phenomenon”. It's not dangerous at all and is in fact very common, but most people don't even notice it if they're not paying attention to it.


  • 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.
