The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens utilizes and combines non-circularity and thickness differential aspects resulting in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently. |

In particular, the central zone is displaced from the geometric center of the lens. The shape of the central zone is egg or spoon-shaped and is rotationally asymmetrical with one semi-meridian that is shorter than a corresponding semi-meridian. An intermediate transition zone is formed integral with the periphery of the central zone, and a peripheral zone is formed integral with the periphery of the intermediate transition zone, forming a round contact lens. |

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. |

The present invention provides a contact lens having an orientation/stabilization and optionally translation feature that does not provide an prism optical distortion and can effectively maintain a predetermined orientation of the lens on an eye. Like a conventional lens ballast, the orientation feature of the invention works by weighing the lens at its lower half portion, causing it to come to an equilibrium position on the eye. With such orientation feature, the optical zone of the anterior surface can be designed independently to provide an optimal visual performance. |

The present invention is related to a method for designing and making a contact lens which comprises stiffening rib features that provide even distribution of pressure from the lens over the cornea of an eye and/or allows the lens structure to maintain balance of forces for consistent and correct lens orientation on an eye during lens translation or eye lid movement. The invention also provides a soft contact lens comprising stiffening rib features that provides localized directional reinforcements to the lens structure to evenly distribute pressure from the lens over the cornea of an eye and/or to maintain balance of forces for consistent and correct lens orientation on an eye during lens translation or eye lid movement. |

A multifocal soft contact lens has a main carrier lens with a distance vision axis coincident with its geometric center and extending transversely through the intersection of transverse horizontal and vertical reference axes, and a smaller near vision lenslet supported on the carrier lens. The lenslet has a near vision axis extending through the horizontal reference axis in a nasally decentered relationship with the distance vision axis. To facilitate the proper rotational placement of the lens on the eye of a wearer, a nasal indicator mark is appropriately formed on the horizontal reference axis of the lens in a nasally offset relationship with the carrier lens center. |
