Abstract: An apparatus for performing optometric measurements includes an opto-adjustable lens, the optical power of which is adjustable, with the lens being controlled by a periodic signal configured for producing a periodic optical power wave over time. The apparatus also includes a component for the adjustment of the mean value of the periodic optical power wave. The apparatus further includes an optical projector system for projecting a plane of the opto-adjustable lens onto a plane external to the apparatus, and in that the periodic signal has an amplitude such that it produces an amplitude of the periodic optical power wave corresponding to a chromatic difference of focus between a first wavelength and a second wavelength of visible light which passes the opto-adjustable lens. A system for the performance of optometric measurements and a method for adjusting the optical power of an adjustable lens are related to the apparatus.

Abstract: A device for measuring the optical power of an optical test system includes an optical-object-generating assembly, a support for the optical test system, a digital image detector, and a deflector assembly. The deflector assembly is intended to generate a lateral movement in respect of the initial optical image, thereby producing a shifted optical image and a reference optical image. The digital image detector captures the shifted optical image and the reference optical image in at least one digital image containing data relating to the lateral movement. The device also includes a processing component to calculate the optical power of the optical test system from the data relating to the lateral movement.

Abstract: Methods, systems, and ophthalmic devices are described for correcting a misperception of depth of a moving object. An example ophthalmic device may comprise a first lens having a first optical characteristic that increases a distance of a focal point of a first eye. The ophthalmic device may comprise a second lens having a second optical characteristic that decreases a distance of a focal point of a second eye. The second lens may have a third optical characteristic that reduces a misperception of a distance of an moving object.

Abstract: The present invention describes a refractive multifocal intraocular lens with aspheric geometry on both surfaces in such a way that the map of local optical strength of the lens, combined with the cornea, has a central region of intermediate optical strength surrounded by a ring of maximum optical strength, with a smooth transition between the two, after which it alternates smoothly between rings of varying strengths.

Abstract: A miniaturised instrument for simulating simultaneous vision by generating masks is provided with a single image-forming optical channel. The instrument comprises: a mask-generating element (EGM) which generates at least two complementary masks, with a temporal frequency of alternation such that when one partially blocks the incident light, the other allows the incident light to partially pass, and vice-versa; an adjustable lens (LA) of variable optical power which generates, with said frequency of alternation, at least two different optical powers corresponding to at least two observation distances. The EGM and the LA are located in a single optical channel via which the incident light circulates, such that each mask of the EGM is temporally synchronised with a power of the LA. The combination of all the masks and optical powers produces, via high-speed temporal fusion, a pupil pattern wherein at least two optical powers corresponding to at least two observation distances are combined.
