    摘要: An apparatus and method for measuring wavefront aberrations. The apparatus comprises a reflecting device for reflecting selected portions of the wavefront, an imaging device for capturing information related to the selected portions, and a processor for calculating aberrations of the wavefront from the captured information. The method comprises reflecting selected portions of a wavefront onto the imaging device, capturing information related to the selected portions, and processing the captured information to derive the aberrations.

    摘要: A method is provided which is used to design soft contact lens via corneal topographic analysis. The topography of the cornea is matched to a corresponding topography of a soft contact lens. A geometrical transformation which maps the corneal elevation onto the back surface of an unflexed soft contact lens is used to minimize errors induced by flexure of the lens. The mapping transformation takes into account the effects of flexure. As a result, the contact lens has a back surface with a curvature which matches the specific elevations of the cornea, while the front surface can be spherical or any desired symmetrical or asymmetrical shape.

    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: Translating, multifocal contact lens pairs with optical power zones which are dissimilar between the first and second lenses of the pair are utilized for correcting presbyopia in the wearer. Each lens may differ in segment height, power, asphericity, shape, orientation and/or inset of the optical power subzones thereby providing clear and comfortable vision at far, intermediate and near distances.
