Normal vision, or 20/20 vision, means that a person can read the smallest letters or see the pictures on an eye chart when standing 20 feet away from the chart.

Migraine Headaches

This kind of headache is also common. Migraine pain is related to activity in the brain that swells blood vessels of the scalp, causing throbbing pain, nausea, sensitivity to light, sounds, or odors, and pain that increases with movement. The exact cause of migraines is still unknown. About one in 10 people suffer from migraines, and they affect more women than men. Migraines can run in families and can affect young children as well.
