Why do I get a blind spot followed by swirling patterns that zig zag in an arc that last for about 15 minutes with no pain?

    It seems like it is quite common. On the back of our eye, the retina is the stuff that detects the light. All the information that the retina picks up is sent to the brain through the optic nerve. The only problem is that the optic nerve needs a way to get out of the eye. The place where it leaves is where we have our blind spot. Since we have 2 eyes that can move around, we don't notice the blind spot often.
