One embodiment of a contact lens includes a lens body configured to fit directly on the surface of the eye and legible characters positioned on the lens body. Another embodiment of a contact lens comprises a lens body including polymeric material and a lens enhancing material (e.g., ink, silicone material, medicament material, and the like) encapsulated in the polymeric material. The lens enhancing material can be in the form of isolated sections distributed in the surrounding polymeric material. Methods of making contact lenses include forming a first lens layer including a first surface, forming a pattern on the first surface, and forming a second lens layer over the pattern.

A contact lens package assembly includes a sealable primary lens package, at least one contact lens sealed within the primary lens package, and a sealable secondary lens package. The primary lens package is sealed within the secondary lens package to increase a shelf life of the at least one contact lens. The secondary lens package may be resealable. The secondary lens package may be configured to retain a plurality of primary lens packages. The contact lens package assembly may further include at least one inert gas sealed within the secondary lens package and outside of the primary lens package.

A contact lens package includes a multi-layer laminate substrate and a cover sheet. The multi-layer laminate substrate includes a first polymer layer, a first metal layer and at least one pre-formed lens receiving portion that is sized to hold at least a portion of a contact lens. The cover sheet is removably secured to the substrate and configured to seal a contact lens within the at least one lens receiving portion. The substrate has sufficient structural integrity to maintain a shape of the lens receiving portion.

A contact lens package includes a first package layer, a second package layer, a lens receiving area defined between the first and second package layers, and first and second seal portions. The first seal portion extends around a first portion of the lens receiving area. The second seal portion extends around a second portion of the lens receiving area. The second seal portion has different sealing properties than the first seal portion. The first seal portion may include a releasable seal between the first and second package layers, and the second seal portion may include a permanent seal between the first and second package layers.
摘要:
One embodiment of an ocular lens includes a lens body configured to contact an eye where the lens body has an optic zone shaped to direct central light towards a central focal point of a central region of a retina of the eye. At least one optic feature of the lens body has a characteristic that directs peripheral light off axis into the eye away from the central region of the retina. Another has embodiment of an ocular lens at least one isolated feature of the lens body that has a characteristic of directing peripheral light off axis into the eye away from the central region of the retina. Methods of making contact lenses include forming the features during the manufacturing process.
