Hi, my right eye seems to pulsate and go blurry/jittery. Throughout the day everyday for anywhere between 1-4hrs. when i cover the affected eye my vision returns to normal. An interesting point is that when i seem to do my resistance exercising the problem goes away almost instantly and will return 2 hours after exercise. I have had 1 or 2 days per week were the problem does not occur. I have seen opticians, had eye drops and nobody seems to know what it could be. Any help would be greatly appreciated. Many thanks, Andy
