Abstract:
The invention is directed to non-corrective unitary lens eyeglasses and safety helmets including a one-piece shield and a method for making such a one-piece shield. The method is for designing a one-piece shield for non-corrective unitary lens eyeglasses or a safety helmet, whereby the shield has a front and a back surface, and is computer-implemented with the steps: providing a front surface geometry of the shield; providing a local relationship of the front surface geometry with respect to a center of rotation of a wearer's eye; and, calculating a portion of a back surface geometry attributed to the wearer's eye by establishing non-zero minus power and minimizing prism. The portion of the back surface geometry is a freeform surface geometry.

Claim (Index 12):
A computer-implemented method for designing a one-piece shield for non-corrective unitary lens eyeglasses or safety helmets, said shield having a front surface and a back surface, the method comprising the steps of:\n providing a front surface geometry of said shield; providing a predetermined local relationship of said front surface geometry with respect to a predetermined center of rotation of at least one of a wearer's eyes; and, calculating a predetermined portion of a back surface geometry of said shield attributed to said at least one of said wearer's eyes by establishing non-zero minus power and minimizing prism as worn for a plurality of wearer's lines of sight intersecting said back surface within said predetermined portion and said front surface due to eye rotations of said at least one of said wearer's eyes around said predetermined center of rotation of said at least one of said wearer's eyes, whereby said non-zero minus power within said portion is smaller than 0.12 D, whereby said predetermined portion of said back surface geometry is a freeform surface geometry.
