The optic doc diagx it as the cranial nerve to the eye becoming affect. The more fatigued I am the worse the double or triple vision. If I can get sleep, or a nap it is manageable. I do have a prism in that glass lens on the affected eye. It is lateral layering double and triple vision, not side by side.

The blurred vision, once I turned 40 got bad fast. Especially for computer use, I need to take breaks or the neck strain flares me.
