Or, it can be a symptom of a stroke that's already occurred. Vision complications due to a stroke depend on where the stroke occurs. The majority of visual processing occurs in the occipital lobe, in the back of the brain. Most strokes affect one side of the brain. If the right occipital lobe is injured, the left field of vision in each eye may be affected. A stroke that affects the left occipital lobe may disturb the right field of vision in each eye. Rarely, both sides of the brain are affected, but this can result in blindness.
Possible warning signs of stroke include: 1  Sudden weakness or numbness in the face, arm, or leg on one side of the body. 2  Abrupt loss of vision, strength, coordination, sensation, speech, or the ability to understand speech. These symptoms may become more marked over time. 3  Sudden dimness of vision, especially in one eye.
