She does not agree with the other doctors I saw that my distorted vision and the numbness on my right side are simply caused the strain of needing stronger glasses. It turns out that my eyes are actually quite fine, thank you, although my prescription has worsened a little in the past two years. I still only need to wear glasses to look into the distance, not for reading, and not all the time.
I'm going back on Friday to be seen by a neurologist she recommends; she suspects a problem with blood flow in the arteries in my head and they'll do more tests. She wasn't worried, though; she thinks it could be treated by some simple medications, more sleep and less stress.
