  • Patent number: 8308292
    Abstract: A soft contact lens for fitting to a cornea includes a lens main body made of a light permeable member. The lens main body has a diameter larger than that of a light-shielding portion which shields incident light incident to the cornea. The light-shielding portion includes a main body constituting a light-shielding member, an aperture that allows incident light to be transmitted, the aperture being positioned on a position of the main body of the light-shielding portion, and multiple holes that maintain a scotopic vision and a night vision, the holes being provided around the aperture in the main body of the light-shielding portion and each of the holes having a diameter smaller than that of the aperture.

  • Patent number: 8292430
    Abstract: Provided is a method for manufacturing a tinted semi-finished lens that uses polycarbonate, has high light shielding effect, has impact resistance even after polishing, and can have a uniform tint. In particular, in order to provide a tinted semi-finished lens that has the same light shielding at the lens center and the lens edge when a wearer looks through the tinted lens, and furthermore, that seems to have the same light shielding when a third party looks at the wearer, a tinted layer having a uniform thickness and a transparent layer on the back side are integrally formed. Furthermore, in order to provide the impact resistance to either of the resins included in the layers, a low flow resin having a large molecular weight and a short flow length is used.

  • Publication number: 20120147320
    Abstract: Various embodiments of the present invention provide systems, methods, and processes for constructing a contact lens. In one embodiment, a contact lens assembly is provided, comprising: a curved polymer polarizer with an aperture; a lenslet disposed inside the aperture, wherein the lenslet enables imaging near objects; and a filter attached to the lenslet. In further embodiments, a method for fabricating a flexible contact lens is provided, comprising: fabricating an element having an extrusion; providing a front concave mold, wherein the front mold has an intrusion to accommodate the extrusion of the optical element; affixing the extrusion of the optical element to the intrusion of the front mold; attaching a back convex mold to the front concave mold, thereby forming a mold cavity; and filling the mold cavity with a pre-polymerized liquid, whereby upon polymerization, the pre-polymerized liquid forms the flexible contact lens and the optical element is partially encapsulated within the lens.
