Hi Strizzlow - to be honest I feel it is the same strained feeling like I can't see if I cover one eye....but I looking at your example I do kinda get where your coming from. I feel my vision looks patchy but if I look at the patchy area it is ok?? Is this making any sense!! haha. so maybe it is a form of the shifting you describe?? How are you getting on with finding your answers???

With the blurring and even more bizarrely if I look through a crack in my fingers my blurred vision resolves itself...strange??
