Eyewear

Safety eyewear is presented which is provided with particulate sealing around the inside periphery of the lens/lenses and having temples that provide adjustment of the eyewear to a pantoscopic angle. The eyewear is provided with an adjustable strap assembly for better fit to the wearer's head. The eyewear lens/frame includes a plurality of projections that define various pantoscopic angles. The temple end piece includes a set of recesses that engage the projections formed on the lens/frame which temple end piece is rotated relative to the lens/frame to set the pantoscopic angle. The adjustable strap assembly further adjust the fit of the eyewear and can be unbuckled for snaplocked attachment of the eyewear directly to other safety equipment such as noise suppression ear muffs, communication head phones, breathing masks and the like.

Protective eyewear with adjustable strap

Eyewear having a temple body that provides for adjustment of the temple length. The temple adjustment housing has an interior cavity. Formed within the interior cavity is a longitudinal groove. The temple adjustment housing has at least one relief cut for receiving at least one projection located on the cylindrical temple tip. The temple tip is inserted into the circular opening and moved horizontally to adjust to the desired length. The temple tip is then rotated to lock into place the projections into the relief cuts.

Temple adjustment device

Safety eyewear is presented which is provided with particulate and liquid sealing around a frame containing lens/lenses and having temples that provide adjustment of the eyewear to a pantoscopic angle. The eyewear is provided with an adjustable strap assembly for better fit to the wearer's head. The eyewear lens/frame includes a plurality of projections that define various pantoscopic angles. The temple end piece includes a set of recesses that engage the projections formed on the lens/frame which temple end piece is rotated relative to the lens/frame to set the pantoscopic angle. The adjustable strap assembly further adjust the fit of the eyewear and can be unbuckled for snaplocked attachment of the eyewear directly to other safety equipment such as noise suppression ear muffs, communication head phones, breathing masks and the like. A plurality of ventilation channels is disposed on the frame to provide indirect ventilation. The frame includes a skirt which is designed to prevent unwanted foreign matter, including liquids, from entering underneath the eyewear and making contact with the eyes of a user.

Piano lenses and associated eyewear incorporating parabolic and hyperbolic arcs are provided which are particularly useful in safety and recreational applications.

Parabolic and hyperbolic aspheric eyewear

Safety eyewear is presented which is provided with particulate sealing around a frame containing lens/lenses and having temples that provide adjustment of the eyewear to a pantoscopic angle. The eyewear is provided with an adjustable strap assembly for better fit to the wearer's head. The eyewear lens/frame includes a plurality of projections that define various pantoscopic angles. The temple end piece includes a set of recesses that engage the projections formed on the lens/frame which temple end piece is rotated relative to the lens/frame to set the pantoscopic angle. The adjustable strap assembly further adjust the fit of the eyewear and can be unbuckled for snaplocked attachment of the eyewear directly to other safety equipment such as noise suppression ear muffs, communication head phones, breathing masks and the like. A plurality of ventilation channels is disposed on the frame to provide indirect ventilation.

Eyewear with hingedly attached strapped head retainer

A novel plano lens and eyewear incorporating such lens is presented wherein the piano lens comprises a front surface curvature which is created by rotating an aspheric shape about an axis which is offset from an axis of the aspheric shape. In a preferred embodiment, the aspheric shape is an ellipse or at least is an aspheric shape, a segment of which has an elliptical arc. This elliptical arc is rotated about an axis spaced (offset) some distance from a major or minor axis of the ellipse. In a more preferred embodiment, the ellipse is rotated about an axis spaced from and parallel to the major or minor axis of the ellipse, but in the same plane as the ellipse. The resulting surface of this preferred lens configuration will have a cross-section in a first axis which is a segment of an ellipse, and a cross-section in a second axis (perpendicular to the first axis) which is a segment of a circle. A significant feature of the preferred front lens configuration is that the surface generated is rotationally symmetric.
