The present invention is directed to a method and means for enabling contact lens wearers to photograph their own eyes using an electronic device with a camera such as an iPhone with a macro lens, for example, Olloclip&#xae; Macro Pro Lens Set 7&#xd7; lens, and a custom three-dimensional printed eyecup attachment. The eyecup attachment is designed to position the camera at a suitable and reproducible distance from the eye to ensure that the system can focus appropriately on the lens details. The eyecup attachment also serves to block stray light and diffuse the ambient lighting. In addition, the eyecup attachment ensures that the camera is held in the correct orientation while photos are being captured. The capture images are analyzed using image processing software to determine the angel of rotation of the contact lens.

Method and means for evaluating toric contact lens rotational stability

A method of measuring the thickness of an ophthalmic lens includes forming an ophthalmic lens over a convexly curved surface of a forming optic, the ophthalmic lens including a light absorptive component, and with the ophthalmic lens remaining over the convexly curved surface of the forming optic, measuring the thickness of the ophthalmic lens using information about the light absorptive component of the ophthalmic lens and an intensity reference value associated with the forming optic. The method includes passing light having a wavelength through the ophthalmic lens and the forming optic, whereupon the light absorptive component of the ophthalmic lens absorbs some of the light passing through the ophthalmic lens. The light passing through the ophthalmic lens and the forming optic, which is not absorbed by the light absorptive component of the ophthalmic lens, is used to generate an image having pixel intensity data.

Systems and methods of using absorptive imaging metrology to measure the thickness of ophthalmic lenses

This invention discloses apparatus for generating an ophthalmic lens with at least a portion of one surface free-formed from a Reactive Mixture. In some embodiments, an ophthalmic lens is formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of Reactive Mixture.

Apparatus for forming an ophthalmic lens

An apparatus and method for forming a contact lens includes submerging a convex optical quality surface of a forming optic in a reservoir containing Lens Reactive Mixture, projecting a first Actinic Radiation with a first wavelength through pre-selected regions of the forming optic that correspond to increased thickness in the lens to be formed for selectively polymerize the Lens Reactive Mixture on a Voxel by Voxel basis; projecting a second Actinic Radiation with a different wavelength through the entire forming optic to selectively polymerize the Lens Reactive Mixture on a Voxel by Voxel basis, removing the forming optic and polymerized Lens Reactive Mixture from the reservoir and applying a Fixing Radiation to form the contact lens.

Multiple-wavelength lens forming system and method

A method of measuring the thickness of an ophthalmic lens includes providing an ophthalmic lens having a light absorptive component, and passing light having a wavelength through the ophthalmic lens whereupon the light absorptive component absorbs some of the light as the light passes through the ophthalmic lens. After the light has passed through the ophthalmic lens, the light is used to generate a digital image for the ophthalmic lens that has pixel intensity data that corresponds to the shape of the ophthalmic lens. Information about the light prior to passing through the ophthalmic lens, the light absorptive component of the ophthalmic lens, and the pixel intensity data is used to calculate a thickness profile for the ophthalmic lens.

Apparatus for formation of an ophthalmic lens precursor and lens

A Free-form contact lens and method of making the same. The lens includes a posterior optical quality surface having a concave shape, an opposing anterior surface having a convex shape both of which join at a lens edge that defines an outer periphery of the contact lens, and at least a first lens feature having a predetermined shape and made of a first polymerized Reactive Mixture. The remainder of the lens is made of a second polymerized Reactive Mixture that is different than the first polymerized Reactive Mixture, and that is covalently bonded thereto.

Methods for incorporating lens features and lenses having such features

This invention discloses methods for generating one or both of an ophthalmic lens precursor with at least a portion of one surface free-formed from a Reactive Mixture. In some embodiments, an ophthalmic lens precursor is formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of Reactive Mixture.
