Is vision connected to blood pressure -- i.E. If I lower my blood pressure, might my vision improve?

Not usually, unless. Your vision is only affected by extremely high blood pressure, when the effects of high BP affect the retinal vasculature ;/or optic nerve (malignant hypertension). Furthermore retinal blood vessels can be blocked causing loss of vision. Too low of BP usually causes people to feel faint ; pass out. Too low of BP has been thought to contribute to worsening of optic nerve blood flow. Goal bp: 115/70.
