Abstract: The disclosure includes core-shell filament composition for additive manufacturing of ophthalmic lenses and ophthalmic lens components. The disclosure also includes a set of criteria for selecting core and shell thermoplastic combinations that exhibit high optical clarity, improved filament inter-strand diffusion, high inter-strand adhesion, and improved manufactured part strength when used in an additive manufacturing method like fused deposition modelling.

Abstract: An optical device including a lens and a control member configured such that motion of the control member produces a change in the optical power provided along an optical axis of the lens. The optical device further includes a framework, a motor and a driving member. The motor includes an output shaft rotatively coupled to said driving member. The motor and the control member are mounted in the framework such that the driving member and the control member mechanically cooperate. The driving member is rotatably mounted in the framework. The optical device comprises biasing means for maintaining the driving member in a predetermined axial position along the output shaft axis and relative to the framework. This optical device can be used in an optometric equipment.

Abstract: The invention relates to a method for determining an ophthalmic lens for a wearer and suitable for correcting the wearer's vision, comprising c) determining a virtual lens by an optimization process involving calculating iteratively a surface of the virtual lens so as to match target optical characteristics of a target lens, checking whether peripheral defocus values of the virtual lens satisfy a predetermined criterion, and if the predetermined criterion is not satisfied, reiterating the calculation of the surface of the virtual lens after modifying the target lens of the previous iteration. The determined ophthalmic lens is defined as being the virtual lens at the end of the optimization process. The invention also relates to an ophthalmic lens for a wearer for correcting the wearer's vision and intended to reduce peripheral defocus.

Abstract: A method of forming an optical lens includes providing a lens having microstructures on a surface thereof and an adhesive layer coated thereon; pressing a coating stack, via a carrier layer attached to a first surface of the coating stack by a release coating, against the adhesive layer, a second surface of the coating stack being in contact with the adhesive layer; and curing the adhesive layer and removing the carrier layer from the first surface of the coating stack via the release coating, wherein a thickness of the adhesive layer is greater than a depth of the microstructures on the surface of the lens.

Abstract: A method comprising providing an article having a non-zero radius of curvature and a thermoplastic film, moving relatively to each other said thermoplastic film and said article to bring them into contact, applying heat to the thermoplastic film so that the heated thermoplastic film shrinks and takes the shape and curvature of the article, resulting in a thermoformed thermoplastic film, and optionally laminating said thermoformed thermoplastic film on a surface of an optical article by means of a layer of adhesive, said layer of adhesive being positioned between the optical article and the thermoplastic film.
