  • Patent number: 6076926
    Abstract: Face conforming eyewear includes a rotation limiting hinged bridge and flexible temples with open barrel hinges to reduce the inflexibility of the eyewear frame. The preferred temples have a greater than 90.degree. movement, up to about 105.degree., with respect to the frame. The extra degrees of movement of the temples and the limited rotational movement of the hinged bridge, from about 4.degree. to about 12.degree., allows opposed sides of the frame and the temples to shift and to absorb pressure when contact has been made with the eyewear, especially when worn in active sports. The bridge can incorporate a single or double three barrel hinged.
