What are the benefits of SPINE hinges?
Quite simply; they grip, they flex, they’re durable and they shut automatically. The grip ensures the frames do not slip down your face, a great feature for active lifestyles. The flex means comfort as SPINE flexes in tune with you and your movements. Durability comes from parts working together as there are 5 working SPINE vertebrae constantly interacting seamlessly with each other to create a 90 degree hinge opening. As every element helps the other to take the strain, they rotate only 18 degrees meaning they share the load, making wear from friction virtually non-existent.
