How to find migraine relief when migraine headaches are very common and affect about 18% of women and 9% of men at some point in their lives. However, this common illness is often misdiagnosed as “tension headache”, “sinus headache”, or allergy. Here are some of the characteristics of migraines that help differentiate them from other headache syndromes: Unilateral headache. A headache that is primarily on one side only, or “unilateral”, is very typical of migraine, but not typical of other headache types. Throbbing. Headaches that throb, or pulse with the heartbeat are more often migraine. Photophobia. Light sensitivity is very common in migraine, but very uncommon in other headaches. Patients often report that light, especially outdoor light, is very bothersome during a headache. FL-41 tint was specifically engineered for migraine patients with light sensitivity. Phonophobia. Sound sensitivity is also common during a migraine. Even the regular sound of the TV can be irritating during a headache. Car Sickness. Adults with migraine often have a history of being carsick or motion sick as children. Note that headache severity is not one of the criteria! Although migraines can be severe, they run on a spectrum – Some people have mild migraines – they might not even take an aspirin for it. Others have severe headaches that land them in the local emergency room. Most migraines are somewhere in-between. The National Headache Foundation supported The National Migraine Treatment Survey, a telephone survey of 500 clinically diagnosed migraine sufferers between the ages of 25 and 45 conducted March 2010. A number of interesting results were reported from this survey: 69% of respondents experienced rapid onset migraine 54% said their prescription oral migraine medication is not useful for every migraine attack 51% are dissatisfied overall with their current medication 41% expressed the need for “the fastest relief possible regardless of form” The idea of “precision” tints has arisen from the May 2011 article in Cephalalgia in which custom optical tints were used to reduce visual sensitivity in migraine patients. In the study, subjects looked into a calorimetry machine and adjusted the mix of different colors they viewed until they found something that they perceived as pleasing. The researchers then used this information to design spectacle tints to give subjects similar effects to what they’d chosen from the calorimeter. To get a “precision tint” would mean visiting an eye care professional who has a calorimetry machine and who can then blend a customized tint for you. This process may cost several hundred dollars and very few eye care professionals have the necessary equipment at this time. Because the FL-41 tint specifically has been shown to be effective for migraine relief, and because the tint can be produced relatively inexpensively and with quality control measures, we’ve chosen to use FL-41. FL-41 blocks light in the blue-green part of the spectrum, which is the color that activates the retinal pathway that modulates migraine and likely other light-sensitive conditions. We are currently using more advanced engineering techniques to produce lens coatings that will perform better than FL-41 for migraine sufferers. These will be available to the public in the future.
