Blue wavelengths of light have been proven to both trigger and exacerbate the pain of migraine headaches. Our red migraine relief glasses are specially designed to block over 99% of blue wavelengths, both preventing and alleviating migraines. One study reported that 94% of patients experienced a reduction of migraine pain within 10 minutes of wearing red lenses, with some patients experiencing total relief in as little as 10 seconds. Red tinted anti-migraine glasses are also highly effective for preventing eye strain caused by long term computer use and photophobia caused by fluorescent lighting. In fact, SomniLight's red tinted migraine glasses are the strongest blue blocking migraine glasses on the market, blocking 20% more blue light than similar rose migraine glasses and fl-41 migraine glasses, offering maximum blue light and fluorescent light protection. Caution: do not wear red glasses while operating a motor vehicle, as traffic lights can become difficult to distinguish.
