What does phosphene mean?
A phosphene is a visual phenomenon in which a person sees flashes of light, usually in response to pressure on the eyeball or a change in air pressure. This can occur when the eye is subjected to a sudden change in pressure, such as during a flight or when scuba diving.
Example
"The scuba diver experienced a phosphene when she rapidly changed depth, seeing flashes of light in her vision."
