    摘要: Aspheric toric lens designs are disclosed which reduce the number of cylindrical axis locations required for stock keeping units in inventory by aspherizing the toric surface thereof. The present invention pertains to ophthalmic lenses, and in particular to contact lenses such as soft hydrogel contact lenses, particularly designed to fit astigmatic patients who are either non-presbyopic or presbyopic. One of the front and back surfaces of the aspheric toric lens defines a spherical surface corresponding at least to the patient's basic distance prescription Rx. The other of the front and back surfaces defines an aspheric toric curve, wherein the toric surface is constructed with aspheric radii, such that the aspheric curve desensitizes axial misalignment of the toric curve by providing an enhanced depth-of-focus. When the aspheric toric surface is on the back surface of the lens, the spherical curve on the front surface of the lens can comprise a single spherical curve corresponding to the patient's basic distance prescription Rx. When the aspheric toric curve is on the front surface of the lens, the spherical curve on the back surface of the lens can comprise a multifocus concentric annular ring spherical surface design.

    摘要: Concentric aspheric multifocal lens designs are disclosed which use a combination of an aspheric front surface, which results in aberration reduction and contrast vision enhancement, along with a concentric multifocal back surface, to produce a lens design which affords clear vision at a distance and also near without a loss in contrast which is generally typical of prior art simultaneous vision, concentric multifocal lens designs. The aspheric surface improves the modulation transfer function (MTF) of the lens eye combination which improves the focus and contrast of both distance and near images. The design form is valid for contact lenses and intraocular lenses.

    摘要: A contact lens incorporating one or more compliant dynamic translation zones fabricated from a material that is readily deformable under eyelid pressure during blinking and which allows for the control over translation of the contact lens on the eye. The one or more compliant dynamic translation zones provide for the comfortable relative movement of the contact lens over the eye.
