When the vitreous gel inside your eye rubs or pulls on the retina, you may see what looks like flashing lights or lightening streaks.
Flashes of light in your vision come from inside your eye and not because of lights or anything else outside.
It can be perceived in one or both of the eyes in different colors, shapes, frequency and duration.
A force or pressure on the retina are most often the causes for the flashes of light.
