This invention relates generally to eyewear, and, in particular, to eyewear having an adjustable nosepiece.
Eyewear typically has a nosepiece that is formed as part of the frame or is secured directly to the lens. Eyewear that incorporates a wraparound lens, commonly referred to as a shield lens, is well known in the art. Eyewear with a wraparound lens is often used by individuals when they are engaged in athletic activities, such as biking, skiing, and running. A problem common with eyewear, such as eyewear with a shield lens, for example, is that the nosepiece is not adjustable. An additional problem is that such eyewear can fog up due to the heat and perspiration generated by the user during athletic activities.
It is an object of the present invention to provide eyewear having an adjustable nosepiece that reduces or overcomes some or all of the difficulties inherent in prior known devices. Particular objects and advantages of the invention will be apparent to those skilled in the art, that is, those who are knowledgeable or experienced in this field of technology, in view of the following disclosure of the invention and detailed description of certain embodiments.

A pair of temple arms is secured to the lens. A nosepiece is secured to the lens and includes a core member having a first end and a second end and a substantially V-shaped body with a closed end of the body being substantially rounded. An outer member substantially encases the elongate member and has a substantially V-shaped body with a closed end of the body being substantially rounded. A first end fitting is connected to the first end of the core member and is received by the first notch, with the first end fitting being substantially flush with the front surface and the peripheral edge surface of the lens. A second end fitting is connected to the second end of the core member and is received by the second notch, with the second end fitting being substantially flush with the front surface and the peripheral edge surface of the lens.
In accordance with yet a further aspect, eyewear includes a first lens having a front surface, a rear surface, a peripheral edge surface, and a notch formed in the recess. A second lens has a front surface, a rear surface, a peripheral edge surface, and a notch formed in the recess. A nosepiece is secured to the first and second lenses and includes a core member having a first end, a second end, and a substantially V-shaped body. An outer member substantially encases the core member and has a substantially V-shaped body. A first end fitting is connected to the first end of the core member and is received by the notch in the first lens. A second end fitting is connected to the second end of the core member and is received by the notch in the second lens.
In accordance with yet another aspect, a nosepiece for eyewear includes a core member having a first end, a second end, and a substantially V-shaped body. An outer member substantially encases the core member and has a substantially V-shaped body. A first end fitting is connected to the first end of the core member. A second end fitting is connected to the second end of the core member.
Substantial advantage is achieved by providing eyewear with an adjustable nosepiece. In particular, certain embodiments provide adjustability for the user, providing improved fit and comfort. Other advantages include an improved aesthetic appearance, the ability to replace the nosepiece with another nosepiece, and improved ventilation.
