Strobing light after exercise

Hello Doctor,
I see flashing lights after I exercise. The lights look like I am looking through a ceiling fan and the blades are the dark spots that break up the light.
I have always seen them after exercise, they show up right in the middle of my vision and appear the most notibly when I look at a dark surface. I often workout hard, and sometimes feel qeezy when I am done. They seem to be most noticeable when I am most queezy. The lights seem to only last 20-30 minutes. I do not suffer from headaches after a workout, nor in general.
Can you help me figure out what this is?

Dear Wricardo,

I would recommend that you seek the care of an eyeMD to determine whether you might have migraine or other condition which is causing the lights.
