Abstract: A slip-resistant eyewear system comprising an eyewear frame generally comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second tension adjusters. First and second bows are coupled to first and second tension adjusters. The system may comprise an eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

Abstract: A slip-resistant eyewear system comprising a nose pad comprising a securing member configured to couple to a portion of an eyewear frame and a flap pivotally coupled to the securing member, wherein an angle formed between the securing member and the flap is an acute angle. Implementations of a flap-style nose pad may comprise a pocket configured to house a preexisting eyewear nose pad therein. Other implementations of the nose pad may be configured to adhere to a preexisting eyewear frame. Use of a higher durometer and material and a lower durometer material to form the nose pads allows for a custom fit to accommodate wearers of varying facial topography avoid slippage of the eyewear system.

Abstract: An anti-slip eyewear system comprising a nosepiece configured to couple to a bridge of an eyewear frame, the nosepiece comprising a core comprised of a first material and an outer layer at least partially surrounding or overlapping the core and comprised of a second material, the second material having a lower durometer than the first material, wherein the second material creates a plurality of Schallamach waves on an outer surface of the nosepiece when the outer layer of the nosepiece is in contact with at least a portion of a face of a user. The first material may have a durometer greater than about Shore 40A on the Shore A hardness scale and the second material may have a durometer less than about Shore 40A on the Shore A hardness scale.

Abstract: An eyewear system comprising 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 further comprises 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.

Abstract: A slip-resistant eyewear system comprising an eyewear frame generally comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second tension adjusters. First and second bows are coupled to first and second tension adjusters. The system may comprise an eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

Abstract: A slip-resistant eyewear system comprising an eyewear frame generally comprises a nosepiece comprising a nosepiece material configured to couple to a bridge of an eyewear frame. The frame comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second spring-loaded tension adjusters. First and second bows are coupled to first and second tension adjusters. A first bow extension element is coupled to the first bow and comprises a first fastening element at a first end of the first bow extension element and a second bow extension element is coupled to the second bow and comprises a second fastening element at a first end of the second bow extension element that is configured to mate with the first fastening element to secure the first and second bow extension elements together.
