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 1):
A non-corrective unitary lens eyeglasses or safety helmet for a wearer, comprising:\n a one-piece shield; said one-piece shield defining a front surface having a front surface geometry and defining a back surface having a back surface geometry; a frame wherein said one-piece shield is mounted or which forms a integral part of said one-piece shield; said frame being configured to dispose said one-piece shield in a predetermined local relationship with respect to the wearer's head and eyes; said wearer's head being one of a plurality of standardized head models of the group including: a head model having the Alderson headform, a head model having the headform according to EN 168, a head model having the headform according to ISO 12311:2013, a head model having the headform according to ISO 12312-1 and a head model having the Canadian headform; said standardized head models each having left and right eyes being located at standardized positions thereby providing respective standardized theoretical centers of rotation of said left and right eyes; respective standardized theoretical monocular pupil distances; and, respective standardized normal lines of sight; and, said one-piece shield being disposed in said predetermined local relationship with respect to said wearer's head and eyes establishing non-zero minus power and prism as worn of less than 0.15 prism diopter within a portion of said back surface surrounding an intersection of wearer's standardized normal line of sight of one of said wearer's eyes with said back surface for all of wearer's lines of sight intersecting said back surface within said portion due to eye rotations of said one of said wearer's eyes around said respective standardized theoretical center of rotation of said one of said wearer's eyes, whereby said non-zero minus power within said portion is less than 0.12 D, whereby said portion is larger than 0.1 cm 2 , whereby said portion of said back surface has a freeform surface geometry.
