I have a visual issue that is in my brain. I will move my head from one point to another and a single visual frame will stick in my head for longer than it should as if my brain is not refreshing the info coming in quickly enough. In other words if the first thing I look at is a tree, then I look over to the road, but I STILL SEE THE TREE. Then a second later my brain picks up the fact that I'm now looking at the road.

This is not good for driving or riding my bike!
