What’s the scientific name of the weird stuff you see when your eyes are closed ?

phosphenes. Phosphenes are visual perceptions of light that can be seen when the eyes are closed, even when light isn’t entering the eye. The word comes from the Greek words phos (light) and phainein (to show). Phosphenes can appear as a variety of shapes, such as sparks, spirals, swirls, squiggles, or glowing circles. They can be caused by a number of things, including:
