With ZEISS SV HD2, single-vision wearers can also enjoy the visual benefits associated with real-time optical optimization for their specific prescription requirements. Once again, variable asphericity is applied at hundreds of points over the entire lens design, immediately prior to fabrication using precision free-form surfacing, in order to virtually eliminate the optical power errors that result from oblique astigmatism during peripheral (off-axis) vision. Wearers will experience the doctor’s specified prescription over more of the lens, resulting in wider, clearer fields of vision with better binocularity.
A powerful optical design engine dynamically manipulates the lens design in real time using computer ray tracing and mathematical optimization algorithms. This allows the applications of independent aspheric optical corrections to hundreds of points over the lens in order to ensure that the intended optical performance is preserved across the entire prescription.
