A few minutes ago I noticed difficulty reading off of the computer. Then, I realized that my vision was disturbed in both eyes. In fact, the jagged pattern I was seeing in both eyes remained even after closing both eyes. It seemed then to me that it must be some kind of problem of interpretation emanating from perhaps my brain. I ve had this happen a couple of times before over the last three months. On these occasions, the jagged pattern went away in just a few minutes.
