From time to time I am not able to see the right side of my field of vision clearly. The left side is perfectly clear, however, the right side is blurred. When I am reading something, for example, a sentence from left to right - the first few words are all clear, but the words on the right are blurred. However the words on the right become progressively clearer from left to right as time passes within 5-10 seconds - and the full sentence slowly reveals itself. BUT - if I go back to the first word of the sentence on the left side of page/screen, and start reading the sentence again, the right side of my field of vision is again blurred, and the process repeats itself.
I am wondering what is causing this behavior where I get blurred vision on one half of my field of vision, but where the blurred vision progressively becomes clearer over a few seconds, from left to right. I have experienced this 2 times already within 2 days.
