Abstract: A method for determining an optical design criterion for designing an optical lens adapted to a sport practice, the method including: defining an evaluation axis for evaluating sensory/motor/cognitive requirement of a sport practice, for each of a plurality of sports; attributing a score to the sport practice on each evaluation axis; determining clusters of sports in which practices have similar score; determining at least one visual need corresponding to each cluster of sports; determining, for each cluster, at least one optical design criterion as a function of the associated visual need; and storing in a memory a record for each cluster, along with each optical design criterion associated with the cluster.

Abstract: A wearable optical device increases a Resolvable Object Distance Range (RODR) thereby reducing focusing demands of a plurality of objects located along a visual angle distance for a user with presbyopia or myopia. The devise includes a negative refractive element and a positive refractive element located along an optical axis. The negative refractive element and the positive refractive element are separated from each other by a separation space and at a separation distance suitable for mounting on a spectacle. A surface of a non-central zone of the negative refractive element or the positive refractive element is a Fresnel surface. The separation space is filled by an intermediate media with a refractive index lower than that of the negative refractive element or the positive refractive element. In one embodiment, the intermediate media is an optical grade resin or polymer. In another embodiment, a spacing seal is located around a periphery of the separation space, and the intermediate media is a low-humidity gas for reducing condensation within the separation space during ambient temperature changes.

Abstract: Apparatuses, systems, and methods relate to technology to identify that a focal length of an adjustable lens is to be modified, where the adjustable lens is supported by a frame. The technology controls a light source to emit light towards the adjustable lens, wherein the light source is supported by the frame and adjusts a curvature of the adjustable lens with the light to modify the focal length of the adjustable lens.

Abstract: A method for designing an eyeglass lens includes: displaying an image upon a display device while maintaining a positional relationship of a face of a subject and the display device; acquiring information in which visual sensitivity of the subject is evaluated on the basis of an impression received by the subject who has viewed the image; and designing an eyeglass lens on the basis of the information in which the sensitivity is evaluated.

Abstract: A progressive lens has an optical center and a geometric center line. The progressive lens further comprises a first surface and a second surface. At least one of the first surface and the second surface is a free-form surface. The free-form surface comprises a nearsight region, a farsight region, and a transition region. The geometric center line passes through the nearsight region, the optical center, and the farsight region. A straight-line distance between a first reference point of the nearsight region and the optical center along a direction of the geometric center line is about 13 mm to about 25 mm. A straight-line distance between a second reference point of the farsight region and the optical center along a direction of the geometric center line is about 2 mm to about 5 mm. The disclosure also provides a progressive glasses.

Abstract: The invention relates to a method for determining a progressive ophthalmic device for personalised visual compensation for an individual, according to which the following steps are performed: a) in a first data acquisition phase, determining at least at a first time preceding the appearance of the presbyopia of this individual, at least one value of at least one individual parameter of said individual, and recording each value of the individual parameter of the wearer in a database, in correlation with an associated temporal indicator, b) in a second determination step of the progressive ophthalmic device for personalised visual compensation, determining a desired value of at least one geometric or optical parameter of said progressive ophthalmic device for visual compensation, taking account of said at least one value of the individual parameter determined in step a) and the associated temporal indicator.

Abstract: Certain embodiments are directed to lenses, devices and/or methods. For example, a lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component C(4,0) and a secondary spherical aberration component C(6,0). The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: (i) a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 0.35, the second RIQ is at least 0.1 and the through focus range is at least 1.8 Diopters; (ii) a RIQ of 0.3 with a through focus slope that improves in a direction of eye growth; and (iii) a RIQ of 0.3 with a through focus slope that degrades in a direction of eye growth. The RIQ may be Visual Strehl Ratio or similar measured along the optical axis for at least one pupil diameter in the range 3 mm to 6 mm, over a spatial frequency range of 0 to 30 cycles/degree inclusive and at a wavelength selected from within the range 540 nm to 590 nm inclusive.

Abstract: An improved method for configuring progressive ophthalmic lenses is disclosed. The method includes computing a traditional merit function with two changes. First, the merit function computation is limited by calculating only a preferred distance from the meridian rather than until 0. Second, an additional term is added to the merit function that calculates the mean sphere at a point that is at a reduced range from the maximum unwanted cylinder, rather than the entire range.

Abstract: Contact lenses incorporate mask lens designs that at least one of slow, retard or preventing myopia progression. The lens includes a first zone at a center of the lens; at least one peripheral zone surrounding the center and having a dioptric power that is different than that at the center; and an opaque mask beginning at a radial distance from the center, thereby providing a lens power profile having substantially equivalent foveal vision correction to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.
