  • Patent number: 9995948
    Abstract: Apparatus and methods are described, including a corrective optical film for converting a corrective single-focal lens to a multi-focal lens and/or a progressive lens. A thickness and/or a curvature of the corrective optical film is different in different regions of the corrective optical film, such that the corrective optical film is configured, upon being adhered to the single-focal lens, to change a focal length of the single-focal lens differently in different regions of the single-focal lens. Other applications are also described.

  • Patent number: 9983459
    Abstract: A tunable acoustic gradient index of refraction (TAG) lens and system are provided that permit, in one aspect, dynamic selection of the lens output, including dynamic focusing and imaging. The system may include a TAG lens and at least one of a source and a detector of electromagnetic radiation. A controller may be provided in electrical communication with the lens and at least one of the source and detector and may be configured to provide a driving signal to control the index of refraction and to provide a synchronizing signal to time at least one of the source and the detector relative to the driving signal. Thus, the controller is able to specify that the source irradiates the lens (or detector detects the lens output) when a desired refractive index distribution is present within the lens, e.g. when a desired lens output is present.

  • Patent number: 9969135
    Abstract: A method using additive manufacturing technologies and processes to manufacture a three-dimensional ophthalmic lens with a high management level of the homogeneity during the construction of the ophthalmic lens, through a control of two technical characteristics of voxel: the ability to modify their viscosity, and the ability to inter-diffuse together to provide a final homogeneous element. These two technical characteristics are managed by the choice of component(s) used to manufacture each voxel and by the kind of physical and/or chemical treatment apply to each of them.
