Article Summary
In order to lessen the frequency and severity of their headaches, migraine sufferers are sometimes instructed to wear eyeglasses with precision-tinted lenses. These are known as prescribed precision ophthalmic tints, or POTs. Up until recently, however, the science behind the POTs/headache relationship wasn’t clearly understood. Now, a team of scientists have used functional magnetic resonance imaging (fMRI) to gain an understanding of just what is taking place.
