An eyeglass manufacturing method using epoxy aberrator includes two lenses with a variable index material, such as epoxy, sandwiched in between. The epoxy is then cured to different indexes of refraction that provide precise corrections for the patient's wavefront aberrations. The present invention further provides a method to produce an eyeglass that corrects higher order aberrations, such as those that occur when retinal tissue is damaged due to glaucoma or macular degeneration. The manufacturing method allows for many different applications including, but not limited to, supervision and transition lenses. |

Optical elements are made using micro-jet printing methods to precisely control the type, position and amount of polymer deposited onto a substrate. In preferred embodiments, the proportions of two or more different polymer compositions are varied over the course of the deposition process to deposit adjoining polymer pixels in the form of a film on the substrate surface. The optical properties of each adjoining polymer pixel can be selected to provide a predetermined optical property, including a specific value of index of refraction. Preferably, the film has a radially non-monotonic refractive index profile and/or an angularly non-monotonic refractive index profile. |

An optical wavefront correction plate incorporates a unique, three-dimensional spatial retardation distribution utilizing the index of refraction change of resin mixture in its cured state. The optical wave plate comprises a pair of transparent plates, containing a layer of a monomers and polymerization initiators, such as resin mixture. This resin mixture exhibits a variable index of refraction as a function of the extent of its curing. Curing of the resin mixture may be made by exposure to light, such as ultraviolet light, and may be varied across and through the surface of the resin mixture to create a particular and unique three-dimensional wavefront retardation profile. The optical wave plate provides improved performance in large area mirrors, lenses, telescopes, microscopes, and ophthalmic diagnostic systems. |

Process for obtaining a transparent article with a refractive index gradient, including the steps of: (1) irradiating a crosslinkable liquid mixture of base photopolymerizable monomers which is modulated spatially in intensity and/or irradiation time to form a structure gradient according to a desired index profile until a self-supporting polymer matrix is obtained; (2) swelling the polymer matrix to thermodynamic equilibrium in a swelling composition containing a polymerization initiator and one or several polymerizable monomers producing a polymer of different refractive index from the refractive index of the matrix obtained in step (1); and (3) polymerizing the swelling composition which has diffused into the matrix homogeneously, thereby obtaining a transparent article with a refractive index gradient. |

In a method of manufacturing a transparent polymer material article having a refractive index gradient the polymer base material is caused to absorb a swelling agent including at least a monomer adapted to yield a polymer having a refractive index different than that of the polymer base material. A first preform having a first geometry is formed from the polymer base material sufficiently polymerized for the first preform to be self-supporting. A confinement space is defined between the first preform and an abutment member having facing it a second geometry at least partly different than the first geometry and having a greater volume than the latter. The first preform is brought into contact in the confinement space with a sufficient quantity of swelling agent for the swelling to which it is then subject to cause it to be urged actively into contact with all points of the second geometry. The resulting polymer material is polymerized and the second preform thus obtained is machined, if necessary, to the required final geometry of the required article. The method finds an application in the manufacture of ophthalmic lenses. |

A refractive index of the lens material varies along the main line of vision at least in the intermediate portion so as to at least partially contribute to the increase in refractive power and correction of aberrations. |

A unifocal ophthalmic lens has part-spherical concave and convex surfaces. Its refractive index varies radially from its optical axis to its periphery. The variation of the refractive index is governed by a law such that the absolute value of the optical power of the lens is significantly greater than its geometrical power when the optical power is computed using the refractive index of the lens on its optical axis. |
