Now you know. By 50 over half of the people have PVDs (posterior vitreous detachments).

What I experienced were actually arcs of flashing lights in 1 eye. The next day I experienced a large amout of floaters, so I went to the Ophthalmologist. He said it was typical symptoms of a vitreous gel separation. No retinal tear. The flashes / arcs of light are seen when the separation occurs. And the floaters occur because of the shrinkage of the gel. It would probably take a few months before they subside a bit. He recommended a retinal specialist just to be on the safe side and just in case it happens in my other eye. He says too many birthdays cause this common problem.
Could be serious disease of the eyes, heart, brain or blood vessels. Could be TIA Could be eye migraine. Use the search feature and archives to read about both. See an Eye MD ophthalmologist and an Internist, cardiologist or family practitioner.
