Optically Decentered Face Shield |
摘要 |
A method of making a protective shield is provided. The method comprises molding an arcuate lens blank having an optical center displaced from an apex of the lens to a position near or beyond the edge of the protective shield. This reduces the object shift as wearer of the lens shifts gaze from a normal straight ahead line of sight to an activity specific line of sight that is vertically displaced from the normal straight ahead line of sight.
