Functional MRI technology is helping us understand how colored lenses can help migraine sufferers.
The research, published in the journal Cephalalgia, shows that looking at the world through tinted glasses can help normalize activity in the brain. Migraine sufferers experience abnormal brain activity when looking at intense patters, but the tinted lenses reduced the phenomenon called hyperactivation. This study built on previous work that found that 42% of migraine patients who see auras experienced a significant decrease in symptoms when they wore precision ophthalmic tints.
