what’s the little bright things we see when it is dark? Or, why we see them?
In: Biology
The scientific term for these is phosphenes, which refers to any time you see light without light actually entering your eye. The cells in your retina are firing for some reason other than light actually hitting them. They can be caused by many different things, including mechanical stimulation (rubbing your eyes), electrical or magnetic stimulation, or just random firings of the cell in your visual system, which you normally don’t notice because you’re busy looking at other stuff. Astronauts even see them when in space because of high energy particles hitting their eyes!
