what does it mean if you see light flashes instead of pitch black when you close your eyes?

Retinal phenomenon: Flashes of light can be due to stimulation of the retinal by either external pressure on the eye, or by pulling on the retina by the vitreous strands within the eye. These flashes are generally very short lived. Longer lasting lights that may form patterns can be due to migraine aura. It is a good idea to have a dilated exam if this is a new or common occurence, especially with new floaters.
