Abstract: An optical lens for use with an eyewear frame includes an inner surface and an outer surface, with the lens being configured to be positionable adjacent a wearer's eye to enable viewing through both the inner and outer surfaces of the lens. The optical lens additionally includes a plurality of magnification regions, with each magnification region extending between the inner surface and the outer surface and being associated with a respective minimum magnification magnitude and a respective peripheral boundary. The peripheral boundaries for the plurality of magnification regions are disposed about a common center of magnification. The lens includes a geometric center residing on at least one of a longitudinal midline of the lens or a latitudinal midline of the lens, with the center of magnification being offset from the geometric center.

Abstract: A progressive addition lens includes a first fitting point, a near vision reference point and a first optical spherical power variation between the first fitting point and the near vision reference point. The lens further includes a second fitting point and a night vision reference point located on a same face of the lens, the night vision reference point being positioned on an eye gaze direction inclined by an upward eye gaze declination angle when the user wears the progressive addition lens mounted in a frame with a downward head declination angle opposite to the upward eye gaze declination angle without moving the frame relatively to the user's face, the progressive addition lens presenting a second optical spherical power variation between the second fitting point and the night vision reference point, the night vision reference point having a lower optical spherical power than the second fitting point.

Abstract: A contact lens (201) and methods of manufacturing such a lens are described. The lens (201) includes an optic zone (202). The optic zone (202) comprises a central region (205), the central region (205) having a first optical axis (219), a base radial curvature power, a base radial sagittal power, and a centre of curvature that is on the first optical axis (219). The optic zone (202) comprises an annular region (203), wherein at a point halfway across the width of the annular region (203) the annular region (203) has a radial curvature power of X, wherein X is greater than the base radial curvature power. The annular region (203) has an off-axis centre of curvature that is a first distance from the optical axis (219) such that, at a point halfway across its width, the annular region (203) has a sagittal power of Y, wherein Y is greater than the base radial sagittal power, and wherein Y is less than X.

Abstract: The invention relates to a method of selection of an ophthalmic lens suitable for correcting at least an optical impairment of an eye of a wearer who observes a screen. According to the invention the method comprises the steps of: determining at least a characteristic of posture of the wearer observing said screen, determining a dioptric power value associated to said vision zone allowing the wearer when wearing the ophthalmic lens to have an easier reading of said screen, determining at least one characteristic of filtering means to adjust the light exposure of the wearer to said screen, and determining the vision zone based on dioptric power value, characteristic of posture of the wearer and characteristic of filtering means so that the vision comfort of the wearer is optimized when wearing the ophthalmic lens while observing a screen

Abstract: A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.
