Apparatus and methods for controlling axial growth with an ocular lens
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 embodiment of an ocular lens has 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.
Systems and methods for the production of contact lenses
An apparatus for spin casting lenses includes a rotatable tube, the rotatable tube defining a longitudinal cavity, wherein the longitudinal cavity is configured to receive molds. According to one exemplary embodiment, the rotatable tube is made of metal and includes a plurality of apertures configured to permit the transmission of actinic radiation.
Systems and methods for printing on a contact lens
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.
METHOD FOR MANUFACTURING TORIC CONTACT LENSES
A method of manufacturing of an astigmatic contact lens having a toric portion and a ballast portion such that said ballast portion causes the toric portion of the contact lens to properly orient in the eye of the wearer. The toric lenses are manufactured by an effective process control method for cylinder axis angle in toric lens production by modifying the target cylinder angle for mold rotation by eliminating the accumulative cylinder axis error from all previous steps including tool making, tool assembly, and molding. The amount modifying the target angle is determined by accurately determine the true cylinder axis on the corresponding mold by using a high-resolution interferometer, such as FISBA FS10M or equivalent models from Trioptics Shape vertical series.
