Hello Doctor, I recently noticed that when I'm in the outside light and when I look somewhere, I see light gray circles moving and changing fast. It is difficult to describe. I only have it in the outside light. Otherwise, I see well, I was on a dilated eye examination in January and everything was fine except for astigmatism. I don't even know how long I have it, I basically see it mainly when I focus on it or when I think about it, or more often when I stare at something. It's a weird. What could it be? It's not Floaters, this is bigger. Thank you. Male, 20yo.
