摘要: Programmable smooth junctions are provided for lenses and molds therefor, particularly for toric lens designs, which enable a numerically controlled (NC) machine to be programmed to machine smooth junctions or transitions between adjacent regions of a lens which have different thicknesses or radii of curvature. First and second mathematical functions f(a) and f(b) are defined which specify the curves of first and second segments of a lens surface. The slope dy/dx is derived of the first and second mathematical functions f(a) and f(b) at the transition between the first and second segments of the lens surface. A mathematical function is defined which describes a desired transition between the first and second segments of the lens. The first and second mathematical functions f(a) and f(b), the derived slopes dy/dx of the first and second mathematical functions f(a) and f(b), and the mathematical function describing the desired transition are then utilized to program a numerically controlled machine to machine the first and second segments of the lens surface and the desired transition between the first and second segments.

摘要: Non-ballasted, eyelid rotationally stabilized designs are disclosed for use in toric or multifocal toric contact lenses. The back surface of the lens includes a toric or multifocal toric surface and also thin top and bottom zones (slab offs) to achieve eyelid rotational orientation and stabilization. The advantage of this technical approach is in mold manufacturing, wherein the design allows the use of any chosen power spherical stock front mold.

摘要: Combined multifocal toric lens designs are disclosed which combine a correction for astigmatism, either corneal or lenticular, with a correction for presbyopia. One of the front and back surfaces of the lens defines a toric surface for an astigmatic optical correction, and one of the front and back surfaces, which can be the same surface or the opposite surface, defines a multifocal surface for a presbyopic optical correction, to provide visual acuity for astigmatic presbyopes. Embodiments are disclosed wherein one surface of the lens design has a combined concentric annular ring, multifocal toric surface, and the other surface of the lens design has a spherical or aspherical surface. In other embodiments, one surface of the lens design has a toric surface for a toric correction, and the other surface of the lens design has a multifocal surface to provide a presbyopic correction, which may include concentric annular ring multifocal lens designs, or other presbyopic lens designs which contain more than one spherical or aspherical power such as aspheres, segments, progressive aspheres, diffractive, birefringent or other concentrics.

摘要: A method of manufacturing complex optical surfaces in soft contact lenses includes a first step of defining the complex optical surfaces with a computer assisted drafting program using a mix of patient determined parameters and selected manufacturing process determined parameters to define a mathematical "meta lens". A machine code data set is then generated to machine a plurality of contact lens mold inserts to define a complex optical surface on each of the inserts. The machining step is conducted with a single point diamond lathe having submicron precision and repeatability. A first and second plurality of intermediate contact lens mold halves are then molded with said contact lens mold inserts to define said complex optical surfaces on said mold halves having micron range transitions between optical surfaces. The complex geometric forms and optical surfaces include bifocal lenses, aspheric lenses, and toric lenses wherein the lenses may include parabolic or elliptical geometry. The first plurality of mold halves is assembled with the second plurality of mold halves with a polymerizable monomer therebetween and polymerized to form a plurality of soft contact lenses having said complex optical surfaces defined thereon.
