What does “Phosphene” mean?
Have you ever closed your eyes and then pressed your eyelids with your fingers? Most of us have done it. What happens when we do that is, we feel a sensation of lights. Each of us might see these lights in different ways. Some might see them as spots while some might see them as lines, floating stars, zigzags, swirls, spirals or squiggles. Everyone sees them is different colours too! So, phosphene can be called a phenomenon characterized by the experience of seeing light without light entering the eye.
