Sudden Loss of Vision
Experiencing a sudden loss of vision can be a frightening and concerning experience. The loss of vision, whether partial or complete, can occur in one or both eyes and can range from mild blurriness to total blindness. Sudden loss of vision is a serious symptom and can indicate a range of underlying conditions, some of which require urgent medical attention.
