Ophthalmic Lens With Depth-Modulated Optical Structures and Methods of Forming
Subsurface optical elements are formed within an ophthalmic lens using modulation of depth to which refractive index change inducing laser pulses are focused within the ophthalmic lens. A system for forming one or more subsurface optical structures within an ophthalmic lens comprises a control unit operatively coupled with a laser pulse source and a focusing assembly. The control unit is configured to control operation of the focusing assembly to sequentially focus each of the sequence of laser pulses onto a respective sub-volume of a sequence of sub-volumes of the ophthalmic lens. The sub-volumes of the sequence of sub-volumes have modulated depths within the ophthalmic lens and varying transverse locations within the ophthalmic lens.
Lens supply system and related methods
The supply systems for providing spectacle ophthalmic lenses have improved efficacy, in particular with respect to lens blank picking performance and/or lens manufacturing performance.
METHODS OF MANUFACTURING AN OPHTHALMIC LENS
Methods of manufacturing an ophthalmic lens are described. The methods include a step of providing an ophthalmic lens; and a step of providing a photocurable film.

At least one actinic radiation source (34) is located in the interior (28) of the container (12). At least one deactivation radiation source (36) is located in the interior (28) of the container (12). A method of customizing a photochromic article (14) includes inserting a photochromic article (14) having at least one non-thermally reversible photochromic material into a container (12) having at least one actinic radiation source (34) and actuating the at least one actinic radiation source (34) to activate the at least one non-thermally reversible photochromic material.
METHOD FOR OBTAINING CONTACT LENSES WITH DYNAMICALLY CONTROLLED SAGITTA AND CLEARANCE
The disclosure generally describes methods, systems and products relating to the development and manufacture of scleral contact lenses. A number of dimensions for the scleral lens is generated based on control points and attendant curvature parameters. Any change to one or more of the curve parameters imparts an improved anterior and posterior surface of the scleral lens and associated thickness, while undesired modifications to control points and other curve parameters remain static inasmuch as the sagittal depth component is an input parameter of the present disclosure.
FORMING A COMBINED LENS
Apparatus and methods are described including adhering a first lens to a second lens such as to form a combined lens having a given optical design, by placing the first lens and the second lens in respective first and second pressure chambers with an adhesive layer disposed between the first lens and the second lens, bringing a convex surface of the first lens into contact with the adhesive layer, and bringing a concave surface of the second lens into contact with the adhesive layer. Other applications are also described.
ASPHERICAL LENS DESIGN WITH POWER DEPENDENT SPHERICAL ABERRATION
Described herein are soft contact lens sets and methods of designing soft contact lens sets based on incorporating different levels of spherical aberration into the lens design depending on the target spherical power. The different levels of spherical aberration are equal to or less than zero D/mm.sup.2, and account for clinically measured population-average ocular spherical aberration, manufacturing variations and generalized accommodative ability.
