With a stroke affecting a visual area of the brain, prolonged loss of blood supply damages the involved tissue. How to flirt with a girl on the street on the extent of brain damage, some restoration of vision can occur while recovering from the stroke.
Arteritis refers to a group of diseases that involve inflammation of arteries, the blood vessels that what causes temporary loss of vision in one eye oxygen-rich blood to the body.

Temporary blindness initially involving one eye is a hallmark symptom of giant cell arteritis, also known as temporal arteritis.
Less commonly, transient blindness can occur with other types of arteritis. Light striking the retina triggers signals that travel via the optic nerve to various areas of the brain, which register and interpret what you see. Several nervous system disorders affecting the optic nerve or visual processing areas of the brain can potentially cause temporary, one-sided blindness. Visual symptoms frequently occur in people with migraines, sometimes even temporary blindness.
Some people have a form of migraines with visual symptoms affecting one eye but without an accompanying headache. Disorders that affect the optic nerve can lead to temporary blindness.
Conditions that cause malfunction of the optic nerve are called optic neuropathies, and numerous disorders and conditions can lead to this problem. Some examples include multiple sclerosis, systemic lupus erythematosus, inflammatory bowel disease and Lyme disease.
A variety of additional nervous system conditions can potentially cause temporary blindness in one eye, including brain or pituitary gland tumors, and conditions that cause increased pressure in the brain, or intracranial hypertension.
