  • Patent number: 8292425
    Abstract: A pair of eyeglasses includes a lens, a couple of right and left elastically deformable frames attached to respective side end portions of the lens, and a couple of right and left temples attached to the respective frames. A frame fitting portion is provided at each of the side end portions of the lens and a lens fitting hole is provided in a front portion of each of the frames. The frame fitting portion fits into the lens fitting hole so that the lens is detachably attached to each of the frames. The volume of the frames is reduced to lighten the weight of the eyeglasses as a whole. With the eyeglasses, a forward vision of a wearer is guaranteed when he leans forward, and easy lens exchange is achieved.

  • Patent number: 7490365
    Abstract: Swimming goggles, wherein belts are fitted to an eye protective eye cup portion, a mounting/dismounting mechanism for mounting and dismounting the goggles on and from a head part is fitted to the belts, whereby since the mounting/dismounting mechanism for mounting and dismounting the goggles on and from the head part is fitted to the belt fitted to the eye cup part, a user can mount and dismount the goggles on and from the head part by merely slightly pulling the belt to connect and disconnect the mounting/dismounting mechanism, and must not extend the belt by pulling to such a length as to provide an allowance for installation on the head, and the swimming goggle making it hard for hairs to be disturbed more than before when installed on the head part can be provided.

  • Patent number: 6845521
    Abstract: The length adjusting mechanism includes an elastic headband member and an engaging member to engage with the headband member. The headband member is provided with a plurality of projected parts which selectively engage with the engaging member. The engaging member includes an insertion hole through which the headband member is inserted and one or more fiting grooves in which projected parts may just settle selectively. At the time of putting the goggles on, a wearer may easily adjust the length with less force than for conventional goggles.
