Ho - Web page: https://patentgrep.com/patent/US8770740B2 ## CPC - G02C 3/003: {Arrangements for fitting and securing to the head in the position of use} - G02C 5/06: with resilient means - G02C 5/16: resilient or with resilient parts - G02C: SPECTACLES; SUNGLASSES OR GOGGLES INSOFAR AS THEY HAVE THE SAME FEATURES AS SPECTACLES; CONTACT LENSES (trial frames for testing the eyes A61B3/04; goggles or eyeshields not having the same features as spectacles A61F9/00) ## Abstract Eyewear which is suitable for routine wear and within masks which are sealed against noxious environmental gases or penetration by water is provided by a frame made up of resilient metal parts including wires to provide the frame with a shape, which facilitates the placement of the eyewear on the head of the user while limiting the movement of the eyewear when in use so as to avoid breaking the seal of a mask inside of which the eyewear is disposed when the mask is donned by the user. The eyewear has a lens holding frame for holding lenses adjacent the eyes of the user's head and connected by a bridge across the user's nose. Flexible members bent arcuately around and in conformance with the sides of the head of the user have a kink whereby to facilitate acceptance between the sides of the head and the seal of the mask with sufficient tightness against the side of the head to limit movement of the frame and the space between the seal and the head thereby avoiding breaking of the seal when the mask is in operation. ## Claims ### Claim 1 Eyewear wearable on the head of a user and inside a mask without interference with the operation of the mask which eyewear comprising: a lens holding frame for holding lenses adjacent to the eyes of the user's head; and two flexible members extend from said frame to rearwardly arc along a bend and then outwardly along an arcuate curve along the sides of the user's head, said flexible members changing in shape after said bend to being flat in conformance with the side of the head and held sufficiently tightly against the sides of the head to limit movement of the frame and avoid breaking of a seal of a mask when worn by the user. ### Claim 2 (depends on 1) The eyewear according to claim 1 wherein said lens holding frame is disposed in a vertical orientation, and said flexible members are round after said bend and then flat in a horizontal orientation when extending outwards along said arcuate curve. ### Claim 3 (depends on 1) The eyewear according to claim 1 wherein said flexible members have hooked ends for wrapping around the ears of the head of the user, said lens holding frame is disposed in a vertical orientation, and said flexible members are round after said bend and adjacent thereto and then flat in a horizontal orientation when extending outwards along said arcuate curve to said hooked ends. ### Claim 4 (depends on 1) The eyewear according to claim 1 wherein said flexible members each have a hinge member between said bend and said arcuate curve of the flexible member. ### Claim 5 (depends on 1) The eyewear according to claim 1 wherein said lens holding frame has right and left lens holding sections, and a bridge section extending between said right and left lens holding sections, and said flexible members each extends away from said bend along said face and then inwardly to connect to said bridge section. ### Claim 6 (depends on 1) The eyewear according to claim 1 wherein said flexible members each extends inwardly to connect to said bridge section via a kink in the flexible member. ### Claim 7 Eyewear wearable on the head of a user and inside a mask without interference with the operation of the mask which eyewear comprising: a lens holding frame for holding lenses adjacent to the eyes of the user's head; two ear pieces; two flexible members each extending from a different side of said frame, each of said flexible members comprises: a first section outwardly extends from said frame along said face and then bends to further extend partly along the side of the head; a second section extends outwardly along an arcuate curve along the side of the head to a different one of said ear pieces; and a hinge member connecting said first section and said second section, and said second section being flat at least adjacent said hinge member in conformance with the side of the head and held sufficiently tightly against the sides of the head to limit movement of the frame and avoid breaking of a seal of a mask when worn by the user. ### Claim 8 (depends on 7) The eyewear according to claim 7 wherein said second section adjacent said hinge member transitions in shape from being round to flat to enable said second section to conform with the side of the head and to be held sufficiently tightly against the sides of the head along a seal of a mask when worn by the user. ### Claim 9 (depends on 7) The eyewear according to claim 7 wherein said second section adjacent said hinge member transitions in shape from being round to flat to a different one of said ear pieces. ### Claim 10 (depends on 7) The eyewear according to claim 7 wherein said lens holding frame has right and left lens holding sections, and a bridge section extending between said right and left lens holding sections, and said flexible members each extends inwardly to connect to said bridge section. ### Claim 11 (depends on 10) The eyewear according to claim 10 wherein said flexible members each extends inwardly to connect to said bridge section via a kink in the flexible member. ### Claim 12 (depends on 7) The eyewear according to claim 7 wherein resilient metal parts provide said frame, and said first section and said second section of each of said flexible members. ### Claim 13 (depends on 12) The eyewear according to claim 12 wherein said metal is alloyed stainless steel or titanium having a thickness to be flexible to conform to and be yieldable with respect to brows of the user and the sides of the head of the user.
