English translation:flashes/flashing lights /phosphenes
Explanation:
The appearance of flashing lights comes from the traction of the vitreous gel on the retina at the time of vitreous separation. Flashes look like twinkles or lightning streaks. You may have experienced the same sensation if you have ever been hit in the eye and seen stars.
http://www.hsc.stonybrook.edu/som/ophthalmology/disorders/fl...

A phosphene is an entoptic phenomenon characterized by the sensation of light from mechanical, electrical, or magnetic stimulation of the eye's retina, or from random firing of cells in the visual system, rather than from light.
http://en.wikipedia.org/wiki/Phosphene

Retinal tissue is stimulated by light but also responds to mechanical disturbances. Flashing lights usually are caused by separation of the posterior vitreous. As the vitreous gel separates from the retina, it stimulates the retinal tissue mechanically, resulting in the release of phosphenes and the sensation of light.
