The present disclosure relates to an eyewear, in particular eyewear suitable for use without nose support/pads.
The following discussion of the background is intended to facilitate an understanding of the present disclosure only. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or is part of the common general knowledge of the person skilled in the art in any jurisdiction as of the priority date of the invention.
Conventional eyeglasses typically include a frame, a pair of temple bars and a nose support, which can be in the form of a pair of nose pads arranged to engage/pinch a bridge of a wearer’s nose. The eyeglasses will be supported on a wearer’s face in part due to the combination of temple bars and nose pads.
However, in some situations the use of nose supports may not be desirable, for example, when the nose bridge is injured. Nose supports may also compromise the aesthetic quality of a wearer’s face. Although some documents may teach the possibility of eyewear without nose support, these documents do not adequately re-distribute weight of the eyewear to avoid the eyewear resting on a wearer’s nose.
There exists a need for an eyewear to alleviate the aforementioned problem.
Other aspects and features of the present disclosure will become apparent to those of ordinary skill in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.
The disclosure seeks to re-distribute the weight of the eyeglass from the nose to the side of the face as posteriorly as possible. The weight is preferably redistributed, via side supports, on a zygomatic region of a person’s face, and more preferably the weight is redistributed on the “zygomatic arch” of a person’s face. In addition, temple cables preferably may be provided so that it can be attached (for example hooked) on to the back of a wearer’s ear. Such temple cables preferably provide a “counterweight” or “support” so the frame of the eyewear does not fall onto the nose when worn. In some embodiments, the support may be shaped and dimensioned so as to contact any part of the wearer’s head.
In an aspect of the disclosure there is an eyewear comprising a frame to receive a pair of lens; a pair of side supports adapted to pivot about a zygomatic region of a wearer’s face; and a pair of temple cables arranged to contact one or more ear portions of the wearer; wherein each of the temple cable is adjustable so as to provide a counter-weight to the frame.
In some embodiments, the eyewear comprises a pair of temple bars extending from the frame, and wherein the pair of temple cables is arranged as an extension from the pair of temple bars. In embodiments where temple bars are present, adjustment to the temple cables may be via movement of the temple cables along a person’s temple bar as desired by a wearer.
In some embodiments, the eyewear comprises a weight attached to an end portion of each of the temple cables.

At least one dimension of the pair of side supports 14 and the temple cables 16 may be adjusted. The said at least one dimension may be a length, a width and/or an angle of the pair of side supports 14 and/or the temple cables 16.
In some embodiments, the material used to form part or whole of the temple cables 16 and/or side supports 14 may be a surgical stainless steel 10/10.
In some embodiments, side support holders may be incorporated in the eyewear 10 to facilitate the attachment of the side supports 14 to the temple bars 18. The side support holders may be attached to the temple bars 18 and may be positioned along various positions along the temple bars 18. In one example, the side support holders include attachments/fasteners in the form of a nickel silver plate or nickel based alloys (e.g. Monel). A plurality of holes may be formed on the plate for fasteners to be attached thereon. For example, four (4) drilled holes each of 1.5 millimeters (mm) diameter may be formed to receive screws. The screws may be 1.4 mm screws.
In some embodiments, the side support holders may incorporate slidable mechanisms to facilitate the movement of the side support holders along the temple bars 18.
In some embodiments, the temple bars 18 and/or the temple cables 16 may be formed of or from an elastic/resilient material.
In some embodiments, the temple cables 16 may be detachable from the eyewear 10. Detachable temple cables 16 can facilitate the replacement and/or removal of the temple cables 16 with relative ease. The detachable temple cables 16 may be achieved by quick-release mechanisms and/or magnetic connectors.
In some embodiments, the side supports 14 and/or the side support holders may be detachable from the temple bars 18. This may be achieved by quick-release mechanisms and/or magnetic connectors.
In some embodiments, the cable temples 16 may be made of or formed from a resilient material of sufficient flexibility to enable a wearer to deform the same when anchored/hooked around the ear portion(s). When the deformation force is removed, it is appreciable that the cable temples 16 will return to its original shape.
The eyewear 100 may comprise a frame 120 for receiving lens 200, a pair of side supports 140 and a pair of temple contacts 160. The temple contacts 160 are pivotably mounted on a respective pair of temple bars 180. The embodiments of
Each side support is in the form of an elongate pad 140. The elongate pad 140 may be attached to an inner surface of the temple bar 180. The elongate pad 140 may be formed from or of silicone material. Compared to the described embodiments, the eyewear 100 is advantageously less bulky and is less conspicuous/visible to a third party. Each silicone pad 140 is suitably shaped and dimensioned to maximize the contact with a zygomatic region, such as a zygomatic arch, of the wearer. It is appreciable that each side support 140 may be customized to the wearer’s head size and/or head profile. A side of the silicone pad 140 may include soft/elastomer material (See
In addition to the side supports 140, each pivotably mounted temple contact 160 may be shaped and dimensioned as an extension of the temple bar 180. The temple contact 160 may be regarded as an integration of functions of the end portion 22 and the temple cable 16 of the earlier described embodiment. The pivot mechanism joining the temple contact 160 to the respective temple bar 180 may be in the form of a hinge 162. The hinge 162 may be a torque or friction hinge operable to resist the pivoting motion so that the temple contact 160 stay in place when adjusted. The hinge 162 may comprise a durable center rivet. The pivotable temple contact 160 advantageously allows a user to easily adjust the contact required with the ear portion (e.g. back of the ear) so that the eyewear may be maintained above the nose to avoid or is arranged to minimize contact with the nose.
It is contemplated that an embodiment of the eyewear without nose support is suited for a variety of applications including the provision of an alternative eyewear for a user who has undergone a nose surgery. In addition, individuals or persons who have acne on their nose may wish to avoid placing eyewear on their nose as that can harbour bacteria causing further spread of acne or preventing proper treatment of acne.
It is further contemplated that an eyewear without nose support may be suitable for the following groups of individuals: individuals who would like to prevent nose dents / marks from occurring on their nose, individuals who like to prevent the weight of the eyeglass contributing to the dark circles around their eyes, and/or women wearing makeup want to avoid ruining their makeup.
It is contemplated that side supports 14 may have more than one cord portions 26 extending from the temple bar 18 and ending with corresponding pads 24. As an example, two cord portions 26 may extend from a temple bar 18 and ending with two corresponding pads 24.
In the described embodiments, the cable temple 16 and/or temple contact 160 may be formed from or of suitable materials that may deform when required but yet maintain certain level of ‘stiffness’ in a manner such as to allow customization to a wearer’s head profile and yet retains its position once adjusted so that the eyewear is elevated above the nose. Examples of such ‘flexible-yet-stiff’ materials include silicone or nitinol. Specific to temple contact 160, the friction or torque hinge 162 may further enhance the ability of the eyewear to be elevated above the nose. It is appreciable that the combination of the cable contact 160 and friction hinge 162 enables a user to adjust the tensile strength / counter force acting on the posterior portion of the ear and opposing the force of gravity so that the eyewear can be elevated above the nose of the wearer.
It should be further appreciated by the person skilled in the art that variations and combinations of features described above, not being alternatives or substitutes, may be combined to form yet further embodiments falling within the intended scope of the invention.
