One of the newest lines I've added to the office is Spine. I have to say I'm loving it and so are my patients. Spine frames feature a patented segmented hinge and cable system that flexes the temples holding the frame in place on the wearers head. It is a great frame for patients of most sizes. I myself have their sunglasses and can say that the frame is extremely comfortable. Not only are they comfortable but the frames are very attractive. I've only had the frames in the office for about 2 weeks and they have been selling like crazy. Check them out!
