The conversation between human and AI assistant.
[|Human|] Yes, I am an advid golfer. Over the last couple of months I become unable to focus over lack of energy in my opinion. But I have eaten apples, oranges, energy drinks (PowerAid/Gatorade, plus some energy bars to help. Most of the time it works ok, but recently the blurry vision needed to complete my putting. I performed admirably, but missed several short putts because of vision problems. I can see the ball in flight of the tee or during approach shots. My doctor is in the process of ordering some tests for irregular heart beat
[|AI|]  Hello! Welcome on Chat Doctor ! I read carefully your question and would recommend first consulting with an ophthalmologist to exclude a possible eye disorder. If the ophthalmologist excludes an eye disorder, I would recommend performing further tests to investigate for the possible causes: - a brain MRI study-visual evoked potentials-vitamin B12 levels-complete blood count for anemia. Hope you will find this answer helpful! Best wishes,
