florescent-light Light sensitivity is a frequent symptom of migraine, but according to a study done earlier this year, a certain kind of light may reduce migraines. A study done by researchers at Beth Israel Deaconess Medical Center (BIDMC) in Boston has found that exposing migraine sufferers to a narrow band of green light can reduce light sensitivity, known as photophobia, and headache severity. The study was published in the May 2016 edition of Brain.

Light is such a potent trigger for migraine that it can intensify an attack within seconds, even in people who are legally blind. Close to 90% of migraineurs have photophobia (light sensitivity), but it was a group of blind migraine sufferers that helped researchers from Beth Deaconess Medical Center in Boston trace the source of a possible problem.

Aura_ss Visual disturbances are most commonly associated with migraine headache. These symptoms can also be related to local eye conditions, such as glaucoma, which can produce a halo effect around objects. Visual disturbances may be warning signs of a stroke, and are termed "transient ischemic attacks." Although these ischemic attacks more commonly occur in older individuals, they can be confused with migraine-related disorders. In migraine, visual disturbances can occur before or during the headache. They may be related to the headache itself, in which case the occurrence of blurred vision and increased headache related to light, or photophobia, are most common.
