A mold for a front curve of an ophthalmic lens includes an inner region having a non-rotationally symmetric shape, an outer region having a rotationally symmetric shape, and a continuous middle region between the inner region and the outer region. A first portion of the middle region is in contact with the inner region, defining a non-rotationally symmetric rim or edge of a front surface of the ophthalmic lens. A second portion of the middle region is in contact with the outer region and is rotationally symmetrical.

Mold for contact lens with non-rotationally symmetric rim or edge

Contact lenses may be designed with locally thinned regions to increase oxygen transmissibility to the eye. The locally thinned regions are preferably positioned outside of the optic zone and in the thicker peripheral zone. For a contact lens formed from a specific material, creating local thinner regions, for example, dimples in the back curve surface of the lens, provides an effective and efficient means for increasing oxygen diffusion.

Contact lenses with improved oxygen transmission

A mold assembly for manufacturing ophthalmic lenses which comprises an anti-tilt feature that prevent relative movement of one half of the mold assembly relative to the other half of the mold assembly. The anti-tilt feature ensures that the edges of the ophthalmic lenses are symmetric around their periphery.

Reduced-tilt back plastic feature for a contact lens mold

A contact lens or pair of contact lenses may be designed such that the contact lens is circular or non-circular, planar or non planar, continuous or discontinuous, or any combination thereof to improve the fit of the contact lens on eye. This improved fit contact lens provides improved centration, improved rotation and/or translation and improved tear exchange on eye.

Contact lens with improved fitting characteristics

A method for optimizing the performance in centration, rotation and stability of contact lenses makes use of the upper and lower eyelid geometries to maximize the lens-lid interaction for two different contact lens positions on the eye. The contact lenses are non-round lenses for maximum interaction with the eyelids.
