Publication number: 20080036963Abstract: A variable lens geometry is constructed through a series of spaced vertical curves on and perpendicular to a horizontal curve. Variable geometry is attained by varying the size of the vertical curves along the horizontal curve. In one embodiment, at least one vertical curve more towards the end or temple region of the lens is smaller than at least one vertical curve more towards the interior or bridge region. In another embodiment, the sizes of the vertical curves decrease along the horizontal curve from the bridge portion to the temple portion.Type: ApplicationFiled: June 10, 2005Publication date: February 14, 2008Inventors: Glen Stanley, Keith Fecteau

Patent number: 6511177Abstract: 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.Type: GrantFiled: December 28, 1999Date of Patent: January 28, 2003Assignee: Cabot Safety Intermediate CorporationInventors: James Hall, Keith Fecteau, Raoul Desy, John Salce

Patent number: 6019469Abstract: 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.Type: GrantFiled: September 8, 1998Date of Patent: February 1, 2000Assignee: Cabot Safety Intermediate CorporationInventors: Keith Fecteau, James Hall, Raoul Desy, John Salce, David M.
