Abstract: An optical article may include a frame, a first active lens arrangement coupled to the frame, and a second active lens arrangement coupled to the frame. The first active lens arrangement and the second active lens arrangement may be lined up abreast with respect to each other. Further, the optical article may include a time-based optical power adjustment mechanism coupled to the first active lens arrangement and the second active lens arrangement. The time-based optical power adjustment mechanism may be configured to vary the optical power of the first active lens arrangement and the second active lens arrangement in accordance with a predetermined adjustment.

Abstract: A method for determining, for a given person, an optical equipment among a set comprising a plurality of optical equipments. The method further includes collecting a plurality of N reference datasets associated to at least one corresponding reference person and collecting a given dataset associated to the given person. Each dataset is indicative of a relative ranking of at least two optical equipments forming a reference subset of the set of optical equipments. The method further includes, based on the given dataset, selecting, among the plurality of N reference datasets, a group of R reference datasets, and predicting at least one optical equipment for the given person among the plurality of optical equipments.

Abstract: Disclosed are optical elements that contains two or more near infrared absorbers and methods of producing the same. Two near infrared absorbers with different near infrared wavelengths absorption ranges and residual colors are mixed with a precursor of an optical substrate. The resulting mixture is subsequently processed to produce optical elements that have a broad near infrared wavelength absorption range and a neutral residual color.

Abstract: Disclosed is a method for determining a filter for an ophthalmic lens to be placed in front of the eye of the wearer, the filter being able to improve or maintain the visual comfort and/or the visual performances of the wearer. The determination method includes: a step of measuring a variable representative of sensitivity of the eye or both eyes of the wearer to a characteristic light flow, and a step of determining at least one optical characteristic of the filter according to the representative variable measured.
