Abstract
An ophthalmic lens with premium vision corrections provides significantly improved visual acuity and contrast sensitivity. The premium vision corrections include precisely correcting for two aberration mode sets simultaneously, second-order astigmatism and fourth-order spherical aberration, instead of correcting for only second-order astigmatism or simultaneously correcting for all aberrations present. Fourth-order astigmatism, sixth-order spherical aberration, and third-order coma are additionally corrected in other premium vision correction schemes. In addition, methods are provided for prescribing and fabricating the premium vision lenses to permit mass customization.
