Saturday, I was just sitting on the couch having some coffee when all of a sudden my left eye filled up with a dark swirling cloud. It cleared up slightly and was a lot less Sunday morning. I was still seeing a smaller swirly cloud and when looking at brightness, it would look like gray snow falling. I just got home from the eye Dr. What has happened is my vritnious has pulled away from my retina in a spot in my left eye. Dr said there's no treatment but it will get a lot better over 3 to 4 months. Common from getting older. If something like this happens to any of you , get to an eye Dr , because if it was detached retina it needs immediate attention. Don't play around with your eyes.
