What does it mean when you close your eyes and see white flashes?

Closed-eye hallucinations are related to a scientific process called phosphenes. These occur as a result of the constant activity between neurons in the brain and your vision. Even when your eyes are closed, you can experience phosphenes. At rest, your retina still continues to produce these electrical charges.
When should you worry about eye flashes?
