My husband has a pair of flight glasses that the gold arms/earpieces have turned green. American Optical suggested I contact your company to see if there was any possibility you might carry the arms or know of any way to fix them. These glasses are of great sentimental value, irreplaceable, & he wears them all the time. Our son wore them during the Gulf War while in Saudi Arabia. He is buried at Arlington National Cemetery so you can see why the glasses mean so much to his dad. I was amazed at the compassion that was shown as well as the quick turn-a-round.
