摘要： A contact lens is provided having a substantially concavo-convex lenticular carrier. The carrier has a palpebral anchor portion which is shaped for seating between the conjunctiva of the lower eyelid and the inferior sclera of the eyeball, so that the carrier is held in place with respect to the lower eyelid by the muscles of the lower eyelid. The carrier also has an optical portion which projects upwardly from the anchor portion and which has a reading vision correction area which lies below the pupil of the eye when the wearer of the lens is looking straight ahead and substantially covers the pupil when the eye is moved to a reading position. The junction between the anchor portion and the optical portion extends substantially along the margin of the lower eyelid. The optical portion may consist solely of a reading vision correction area, so that the lens acts as a "half eye" lens, or may also include one or more distance vision correction areas, so that the lens acts as a true bifocal or trifocal lens.

摘要： A contact lens eyeball centering support of soft material for use in conjunction with hard corneal contact lenses. The support has the form and the material of a soft contact lens and is characterized by the fact that the central optical part is absent, to create a free opening without usual system. A hard corneal contact lens can, when the support is in position on the eye, be positioned into the free central opening without adhesion. The preferred embodiment of the lens eyeball centering support of soft material has an external diameter of approximately 15 mm and an internal diameter that corresponds approximately to the diameter of a standard commercial corneal hard contact lens.

摘要： A soft contact lens for use on the human eye formed from a soft material like silicon or a hydrophilic material. The lens has a generally spherical concave inner surface which conforms to the cornea and a generally convex outer surface. To maintain the correct orientation of the lens when placed on the eye it is provided with a flattened region along a portion of its periphery.

摘要： A system of contact lenses includes at least two contact lenses, each lens having a visual correction for a non-rotationally symmetric eye aberration. Each lens has a different level or degree of a stabilization that is characterized by a thickness differential between a thickness of a stabilization zone and a thickness of a non-stabilization zone.

摘要： A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

摘要： The object of the present invention is to provide an annular device superior to a conventional annular device in the stability over an eyeball when being worn, which overcomes problems caused by wearing a conventional annular device.The above object is attained by preparing an annular device to be worn over the surface of the sclera, the annular device including an opening exposing the cornea and one or a plurality of approximately encircling grooves on an intermediate part between an inner rim part and an outer rim part. The annular device has a maximum thickness preferably in the intermediate part.
