Method of coating a lens and lens support
The present invention relates to a method of coating a lens, such as a segmented multifocal lens. The method includes, providing a lens support (1), which is in the form of a ring, that includes a central axis (11), an outer wall (14), an inner wall (17) that is positioned between the central axis and the outer wall, an upper beveled surface (20) that converges downward toward the central axis, and a lower surface (29). The method further includes positioning a lens (3) such that an outer edge (74) of a forward surface (65) thereof abuts a portion of the upper beveled surface of the lens support. At least one coating composition is applied over the rear surface (68) of the lens, so as to form a coated lens (3) having at least one coating layer (89) over the rear surface thereof.
Spectacle lens and method for making the same
A method for manufacturing a spectacle lens includes the steps of providing an integral main lens. The integral main lens has a front surface and a back surface and is at least one selected from a group consisting of a spherical power lens, an astigmatic power lens, and a lens having a main curvature of the front surface in a first meridian and a main curvature of the back surface in the first meridian which are different so as to provide for a spherical power different from zero; and applying at least one additional lens element to at least a part of the front surface and/or at least a part of the back surface, wherein the at least one additional lens element includes at least one layer having a multitude of layer elements, in particular printed layer elements. Further, the invention is directed to a corresponding spectacle lens.
Accommodating intraocular lens
An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.

SPECTACLE LENS AND METHOD FOR PRODUCING A SPECTACLE LENS
A spectacle lens, which is manufactured by additive manufacturing, includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.
Surface adhering lens
A lens structure includes an elastomer formed as a lens. The lens has a planar surface and a curved surface opposed to the planar surface. The elastomer of the lens structure may be formed of a base polymer polydimethylsiloxane (PDMS) material. When the lens structure is applied proximate to a camera sensor array of an electronic device, such as a cell phone or a tablet, the combination can function as microscope. By altering parameters of the lens, such as the radius of curvature, it is possible to achieve a wide range of magnification.
