When I look at the sky or a blank wall, I see clear circles and zig zag lines, but I also see flickering white lights. When I close my eyes I see a group of red and green lights that crossed my eyes, I sometimes see them in the dark as well. I was wondering if this is snow vision. I red and green lights I've always seen since I was a child but not the white flickering lights. I was also wondering if the floaters will ever disappear, I've been seeing them for over a month now.
