What visual disturbance is commonly associated with migraines?

The visual disturbance commonly associated with migraines is characterized by flashes and zigzag lights. This phenomenon, often referred to as a visual aura, can occur before or during a migraine attack. These visual disturbances result from the brain’s abnormal activity and can manifest as shimmering lights, zigzag patterns, or even temporary loss of vision in some cases. Understanding this visual symptom is crucial for distinguishing migraines from other types of headaches, as it often precedes the onset of a migraine and serves as a warning sign for the individual.

While halos around lights, blurry vision, and ocular migraines can also be associated with various eye conditions or headaches, they are not as specifically linked to the typical presentation of migraines as the flashes and zigzag lights are. Therefore, recognizing these patterns as a hallmark of migraine-related visual disturbances is important in the context of optometry and patient care.
