light flash phenomenon




A visual effect experienced when a person is exposed to high-energy particles; it appears similar to but brighter than a shooting star in the night sky. Although the exact mechanism that causes the phenomenon is unknown, it is believed that visual flashes result from direct ionizing energy loss as the particle traverses the cells of the eye.
