Mechanical phosphene. Mechanical phosphenes result from exposure of the eyeball to a stimulus that is not capable of causing the classic phosphene sensation.
Mechanical phosphenes are also known as "fantastic visual sensations" or "pseudo-epileptic phenomena". Such phenomena occur mainly in young people and can be associated with head injuries, taking certain medications, as well as working with computers - a way of life familiar to modern youth. This is how mechanical types of phosphenes appeared. They differ from the type of phosphene visual image that people are accustomed to from birth. This is primarily due to medications and brain damage, including those resulting from severe trauma.
