Ocular migraines are transient, painless episodes that involve visual disturbances, such as blind spots, wavy lines, zigzag lines, moving colors and flashing lights. Although ocular migraines can be alarming, especially on the first occurrence, they usually last less than 30 minutes and have no lasting health consequences, reports All About Vision. Like other types of migraines, episodes can occur during periods of tiredness or following the ingestion of certain foods, such as cheese or red wine. Ocular migraines may have a hereditary basis.

Macular degeneration is a potentially serious, age-related condition that involves the breakdown of the macula, the central portion of the retina. It is the leading cause of severe vision loss and blindness in the United States, reports AMD.org. The condition attacks central vision but spares peripheral vision.
