So, sometimes maybe I'm playing PS3 for a long period of time or I was simply sitting down. Recently I was at the driving range, reached down to pick up a golf ball and when I got back up I periodically almost lost my full sight in both eyes, weird fuzzy figures starting encroaching from the sides of my eyes. Then It slowly went a way and I finished off my bucket of balls. Although over the year I've noticed that this happens sometimes when I'm getting up from doing other things, say maybe playing PS3 for an extended period of time. Although it never got to the point where it almost covered the middle of my eyes. The feeling of it is almost blissful but I'm worried if this is a bad thing.
