Ovation lenses deliver clear, seamless vision for every wearer – whether farsighted or nearsighted • A true aspheric lens, Ovation provides great looks combined with a flatter lens profile and the comfort of thinner, lighter materials Customized progression lengths Hyperopic and myopic patients need different progression lengths to accommodate the vertical prismatic effect of plus and minus progressive lenses • With a plus lens, light from a near object is converged or deviated upward toward the base or center of the lens, displacing the object lower in the lens • With a minus lens, light from a near object is diverged or deviated downward toward the base or edge of the lens, displacing the object higher in the lens Customized near-vision decentration Hyperopic and myopic patients need near-vision decentration to accommodate the lateral prismatic effect of plus and minus progressive lenses • With a plus lens, light from a near object is converged or deviated laterally toward the base or center of the lens, causing the wearer’s eyes to converge more in a corrective lens • With a minus lens, light from a near object is diverged or deviated laterally toward the base or edge of the lens, causing the wearer’s eyes to converge less in a corrective lens
