Worrisome: When standing quickly, the blood pressure can temporarily drop causing dizziness and blurred or dark vision. The visual changes should occur in both eyes. If the vision is changing in only one eye, then I would be concerned about a circulation problem with that eye. See an ophthalmologist for evaluation.
