Migraine is an illness with a throbbing pain on one side of the head, and is usually accompanied by photophobia towards sunlight or lighting. It is reported that this photosensitivity is caused by Intrinsically Photosensitive Retinal Ganglion Cell (ipRGC). At night, it is best to avoid light at the peak wavelength of ipRGC (480nm) that may cause migraine.
