Conventional aspheric and atoric single vision lenses can only be designed for a very limited number of "average" sphere powers across the Rx range. As a result, most prescriptions suffer some degree of power error in the lens periphery.
The ZEISS 3D Single Vision uses ZEISS freeform technology to eliminate the visual compromises found in conventional single vision designs.
ZEISS 3D Single Vision lenses are designed for each consumer‘s prescription including: sphere, cylinder, axis, prism and prism base. Point-by-point optimization is applied over the entire lens, leading to an even more comfortable single vision design.
