Vision problems please help me!?

Ok so I just got this circle thi ng in my eye (like it made a distinct circle shape in the corner of my eye and it moved in a zig zag way. So it was a moving circle. I'm had things similar to these before and I guess they are called Auroras? But this seems different. after the zig zag seemed to have disappeared I seem to have a lot of blind spot and although cannot see them distinctly My vision definitely seems like I have a lot of blind spots. Will I got blind? Please help!
