BACKGROUND

[0006] 1. Field of the Invention

[0007] Exemplary embodiments generally relate to an eyewear system design for enhanced user comfort and ease of use.

[0008] 2. Related Art

[0009] Eyewear is generally designed to fit a pre-determined face shape and anatomical structure, which causes many wearers to experience a poor fit, particularly for eyewear systems that require a precise declination angle for proper use, such as by non-limiting example, when the eyewear system comprises one or more loupes. Conventional eyewear typically relies on a user altering an angle of the bows of the eyewear frame relative to a horizontal axis extending from the top of the user’s ears in order to adjust the declination angle of the eyewear frame which results in an unstable and often uncomfortable fit.

SUMMARY

[0010] Implementations of an eyewear system may comprise an eyewear frame comprising a first side bow component and a second side bow component, an auxiliary frame comprising an auxiliary top bar, an auxiliary first side bow component and an auxiliary second side bar component, the auxiliary first side bow component and the auxiliary second side bow component pivotally coupled to the first side bow component and the second side bow component, respectively. The system may further comprise a declination angle adjuster positioned proximal a bridge of the eyewear frame, the declination angle adjuster comprising a rotatable member therein and a vertical extension member extending from the eyewear frame and at least partially into the declination angle adjuster, the vertical extension member configured to engage the rotatable member within the declination angle adjuster.

[0011] Particular aspects may comprise one or more of the following features. The rotatable member may be threaded. The vertical extension member may be threaded. The vertical extension member may be arced. The rotatable member may comprise a channel at least partially therethrough that is configured to receive a tool that facilitates rotation of the rotatable member. The first side bow component and the second side bow component each may comprise a slot configured to receive a protrusion of the auxiliary first side bow component and the auxiliary second side bow component, respectively. The rotatable member and the vertical extension member may comprise a plurality of complementary teeth and notches. The declination angle adjuster may be further configured to couple a light thereto. [0012] Implementations of an eyewear system may comprise an eyewear frame comprising a first side bow component and a second side bow component, an auxiliary frame comprising an auxiliary top bar, an auxiliary first side bow component and an auxiliary second side bar component, the auxiliary first side bow component and the auxiliary second side bow component pivotally coupled to the first side bow component and the second side bow component, respectively. The system may further comprise a declination angle adjuster positioned proximal a bridge of the eyewear frame and a vertical extension member extending from the eyewear frame and at least partially into the declination angle adjuster, the vertical extension member comprising an arced shape and configured to change an angle of a lens of the eyewear frame relative to the auxiliary first and second side bow components when the length of the vertical extension member within the declination angle adjuster changes.

[0013] Particular aspects may comprise one or more of the following features. The declination angle adjuster may comprise a rotatable member therein. The rotatable member may be configured to engage the vertical extension member. The rotatable member and the vertical extension member may be threaded. The first side bow component and the second side bow component each may comprise a slot configured to receive a protrusion of the auxiliary first side bow component and the auxiliary second side bow component, respectively.

[0014] Implementations of a method of changing a declination angle of an eyewear frame may comprise changing a portion of a length of a vertical extension member of an eyewear frame that extends within a declination angle adjuster positioned proximal a bridge of the eyewear frame and pivoting a first side bow component and a second side bow component relative to an auxiliary first side bow component and an auxiliary second side bow component, the auxiliary first side bow component and the auxiliary second side bow components coupled to an auxiliary top bar, wherein the pivoting is in response to the changing of the portion of the length of the vertical extension member of the eyewear frame that is within the declination angle adjuster.

[0015] Particular aspects may comprise one or more of the following features. Changing the portion of the length of the vertical extension member may comprise rotating a rotatable member within the declination angle adjuster. The rotatable member may be threaded. The vertical extension member may be threaded. The rotatable member and the vertical extension member may comprise a plurality of complementary teeth and notches. The method may further comprise inserting a tool into a channel extending at least partially through the rotatable member. The method may further comprise coupling a light to the declination angle adjuster.

DETAILED DESCRIPTION

[0021] This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended eyewear systems and/or assembly procedures for eyewear will become apparent for use with implementations of the eyewear systems of this disclosure. Accordingly, for example, although particular eyewear systems are disclosed, such eyewear systems and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such eyewear systems and implementing components, consistent with the intended operation of eyewear.

[0022] FIGS. 1-8 depict an implementation of an eyewear system 100 comprising a declination angle adjuster 108. Traditionally, when a user desires a change in the declination angle of the eyewear lenses 120, the user must adjust the angle at which the bows contact the user’s head proximal the user’s ears which results in an unstable and uncomfortable fit of the overall eyewear frame 101. The declination angle adjuster 108 of FIGS. 1-8 is configured to allow a user to simultaneously adjust the declination angle of the eyewear lenses 120 without the need to adjust the positioning of the bows of the eyewear frame 101 that are in contact with the sides of a user’s head thereby creating a securely fitting, stable, and comfortable eyewear system

100, particularly when the eyewear system 100 also supports the added weight of one or more loupes 119 coupled to one or more lenses 120 of the eyewear system 100. While the declination angle adjuster 108 is shown here positioned proximal to the bridge 109 of the eyewear frame

101, it may be located anywhere along the eyewear frame 101. In addition to the top bar of the eyewear frame 101 that holds the lenses 120 in place and the side bow components 102, 103 of the eyewear frame 101, the eyewear system 100 comprises an auxiliary frame having an auxiliary top bar 105 and auxiliary first and second side bow components 106, 107. The first and second side bow components 102, 103 of the eyewear frame 101 are pivotably coupled to and are configured to move independently of the auxiliary side bow components 106, 107 such that the declination angle of eyewear frame 101 may be adjusted independently without movement of the auxiliary top bar 105 and auxiliary side bow components 106, 107. As shown in FIG. 1, this may be accomplished using a slot 113 in the first and second side bow components 102, 103 of the eyewear frame or the auxiliary first and second side bow components 106, 107 that is configured to mate with a protrusion 114 of the first and second side bow components 102, 103 or the auxiliary first and second side bow components 106, 107. The first and second auxiliary side bow components 106, 107 maybe configured to couple to additional bow elements and/or a strap or other device configured to secure the eyewear system to the user’s head when in use.

[0023] FIGS. 5-6 provide cross-sectional views along Section A of the declination angle adjuster 108 of FIG. 2. The top bar of the eyewear frame 101 comprises a vertical extension member 111 comprising a slight arc along the vertical extension member 111 and comprising a plurality of teeth 116, protrusions, notches 117, or threads 115 along the outer surface of the vertical extension member 111. When a user desires a change in the declination angle of the eyewear frame 101, the user simply adjusts the positioning of the vertical extension member 111 by rotating a rotatable member 110 to raise or lower the vertical extension member 111. This may be accomplished by inserting a tool 121 into a channel 112 extending at least partially into the rotatable member 110, the channel 112 configured to receive the tool 121 to facilitate rotation of the rotatable member 110. When only a slight change in the declination angle is achieved, the number of teeth, protrusions, notches, or threads of the vertical extension that are engaged with the corresponding teeth 116, protrusions, notches 117, or threads 115 of the rotatable member of the declination angle adjuster remain unchanged or only slightly changed. When a greater change to the declination angle is achieved, the rotatable member 110 may be sufficiently rotated to engage more or fewer teeth 116, protrusions, notches 117, or threads 115 of the vertical extension member 111 with the corresponding teeth 116, protrusions, notches 117, or threads 115 in the rotatable member of the declination angle adjuster 108 as shown in FIGS. 5-6. In other embodiments, rather than using a rotatable member 110, the vertical extension member 111 may be held in place using a clamping mechanism or other appropriate securing mechanism within the tension adjuster.

[0024] In some implementations, as shown in FIGS. 7-8, the eyewear system 100 may be configured to allow the optional placement of a light 118 on the declination angle adjuster 108 or auxiliary top bar 105. In some implementations, when inserted, the light 118 may be connected to an internal electrical system. Alternatively, the light 118 may be powered by a battery within the light housing. The light may also have an adjustable declination angle which may be achieved using a metal wire core that retains its shape and positioning until sufficient force is applied to change the shape and positioning of the metal wire core; however other suitable materials and structures may also be used to allow for adjustment of the positioning and declination angle of the light 118.

[0025] It will be understood that implementations are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of a method and/or system implementation for eyewear may be utilized. Accordingly, for example, although eyewear systems may be disclosed, such components may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and/or the like consistent with the intended operation of a method and/or system implementation for eyewear may be used. In places where the description above refers to particular implementations of eyewear, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other eyewear systems.
