@mikepa this is exactly the same diagnosis my 91 year old cousin received last fall. I went with her to the optometrist and her story sounds just like yours. Although I do remember her saying it was like a film over one eye (not cataracts, that was already taken care of many years ago). The diagnosis was confirmed by an opthalmologist. It was driving her crazy because she likes to read and it was becoming difficult. In December, her blurry vision had actually improved. I remember the optometrist not being overly concerned and she gave us quite a detailed explanation.
