Thank you for posting this. I am having a terrible time seeing. I got a new prescription maybe the end of last year or so. That is all a blur and so is my eyesight. I had covid 3 years ago and my body and brains have been haywire ever since. I have the same issues that you are talking about. The confusion, brain fog, fatigue, unable to communicate what you mean, lack of memory all of it and more. You are not alone. It sounds like your doctors are taking very good care of you and that is a very, very big piece of this oddly shaped puzzle!
To better days and good health -XO
