Hello. I am having circle shaped flashes at the corner of my eye only when I look at the side. The flashes are more prominent when I look to the side while turning my head to the same direction. The color varies. Sometimes black, white. I'm guessing that it depends on the lighting conditions. This has been going on for almost 6 months now. I had my eye hit by a ball prior that. I am also myopic. I do have some floaters but I have not experience any veil or shadow in some parts of my vision. Could this be a retinal tear?
