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

Lenses for correcting presbyopia are translating, multifocal contact lenses with pseudotruncations which are asymmetric about the vertical meridian.

Translating presbyopic contact lens

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.

Method for designing non-round soft contact lenses

The invention provides dual stabilization zones that interact with an individual's eyelids so that at least the upper eyelid strikes both stabilization zones of a lens at the same time. The stabilized lenses of the invention maintain their on-eye orientation better as compared to conventionally stabilized lenses.

Rotationally stabilized contact lenses and methods for their design

The invention provides a lens in which the lens periphery is controlled as to each of thickness differential and both the rate of change from thinner to thicker regions and the shape of the transition from thinner to thicker regions within each of the dual thin zones. The lens of the invention substantially reduces the time for the lens' auto-positioning. Additionally, the lenses of the invention maintain their on-eye orientation better as compared to conventionally stabilized lenses.

Rotationally stabilized contact lenses

Contact lenses that have a back edge designed so that the flat portion of the edge does not rest on the wearer's conjunctiva are provided. The lenses of the invention exhibit good lens handling as well as excellent on-eye comfort and movement.

Contact lenses

The invention provides molds useful for the production of lenses with contoured edges. In particular, the molds permit production of a lens with an edge shaped to avoid its impingement on the lens wearer's conjuntival membrane.

Molds for use in contact lens production

The invention provides contact lenses with off-axis bevels. The bevels aid in increasing stability of the lens on the eye and form a smooth junction with the lenticular zone of the lens.

Contact lenses with off-axis bevel

A contact lens and a method of manufacturing a contact lens having areas of different thickness, the contact lens being compensated for differential shrinkage during the manufacturing process. The unwanted toricity induced by the differential shrinkage caused by a particular manufacturing process is experimentally determined, both in terms of angular position and power. The lens compensation is achieved by providing an equal and opposite power to the unwanted toricity induced by the manufacturing process.

The invention provides contact lenses that have contoured lens edges that improve lens handling and comfort.

Contact lenses with contoured edges

The invention provides contact lenses. In particular, the invention relates to contact lenses in which the geometry of the lens periphery remains constant with changes in the optic zone curvature.
