  • the high profile bridge saddle 1320 includes a thicker cross-member portion 122 that causes the bridge of the frame to be positioned higher on the wearer's nose, thereby effectively raising the entire frame on the wearer's face.
  • the wearer can easily and conveniently interchange between the normal profile bridge saddle 120 as illustrated in FIGS. 1-12 and the high profile bridge saddle 1320 of FIG. 13, depending on wearer's viewing requirements, without professional assistance.
  • the bottom portion 1302 of the cross-member portion 122 extends a distance downward between the pair of opposing legs 124 that is greater than the normal profile embodiments of the bridge saddle 120 of FIGS. 1-12.
  • the magnets 130 are positioned near the top portion 1304 of the cross-member portion 122 in a similar manner as shown in the normal profile bridge saddle embodiments of FIGS. 1-12.
  • the focal point of the lenses is raised so that the wearer automatically looks through the lower portion of the lenses, as opposed to the central or upper portions of the lenses, which are the focal point when a normal profile bridge saddle is utilized.
  • the bridge saddle will raise the frames so that the wearer looks straight through the lower lens portion while viewing nearby objects.
  • the height of the extended bottom portion 1302 is a matter of design choice based on, for example, the design configuration of the frames, the attachment position of the bridge saddle to the frame, the size and shape of the optical lenses, the positioning of the concave and convex portions of the lenses within the frames, among other design considerations.
  • a wearer can readily interchange the normal profile bridge saddle 120 of FIGS. 1-12 with the high profile bridge saddle 1320 of FIG. 13 in instances where the wearer is viewing nearby objects or reading literature for extended periods.
  • a wearer who is reading printed material such as a book for an extended period can interchange the normal profile bridge saddle 120 with the high profile bridge saddle 1320 to thereby shift the frames upward on the wearer's face.
  • the wearer does not have to tilt his or her head backward and be subjected to discomfort while reading the printed material through the lower lenses.
  • the bridge saddle 120 of the present invention includes at least one magnet for conveniently fastening the bridge saddle to the ophthalmic frame 100.
  • the bridge saddle that is attached to the frame can be selected to customize the fit to a particular wearer of the frames to thereby improve the comfort of the frame on the face of the wearer.
  • the implementation of the magnets in the bridge saddle overcomes the difficulties observed in the prior art by having to fasten the bridge saddles to the eyeglass frames by screws, or other more cumbersome types of fasteners, such as an adhesive, which can be difficult to apply, time consuming to cure, and/or cause discoloring of the spectacle components that it contacts over time.
  • the use of the magnets makes it easier to readily interchange the bridge saddle during the fitting process.
  • the implementation of the magnets allows the optometrist to make fine adjustments while positioning the bridge saddle on the bridge portion and the wearer's face during the fitting process.
