Medications taken could certainly effect one's vision

The general health of a patient as well as medications taken could certainly effect one's vision. There has been several times that patients came in when a sudden change occurred in their vision. In these cases it was undiagnosed diabetes. The vision returned to the patients previous prescription when the condition was treated. Long term diabetes or hypertension could certainly have a dramatic effect on a patient's vision if not treated. Many times the vision worsens and the loss becomes irreversible. Any condition that can affect the body including the heart, liver or kidneys could certainly affect the eyes.
