Abstract
A unitary lens structure is provided which is employable with spectacles as well as goggles and safety eyewear. The lens is formed as a unitary structure with projections having surfaces which are machinable for prescription eyewear extending from a first side surface of a larger shield. Damage from cracking of the shield at the intersections with the projection perimeters is prevented by non linear connections between the two surfaces.
