A camera viewfinder comprises an electronic display apparatus that is configured for the display of images that are recorded by an image sensor of an electronic camera. The camera viewfinder further comprises two mirrors for reflecting the images displayed by the display apparatus, of which at least one mirror is a free-form surface mirror whose reflective surface is formed as a free-form surface that does not have any continuous translation symmetry or rotational symmetry. At least one of the free-form surface mirrors is adjustable to at least partially compensate a vision defect of a user.

An ophthalmological device according to the embodiments comprises an objective lens, a subjective inspection optical system, and an interference optical system. The subjective inspection optical system includes an optical element capable of correcting aberration of a subject's eye and projects a visual target onto the subject's eye via the objective lens and the optical element. The interference optical system splits light from a light source into reference light and measurement light, projects the measurement light onto the subject's eye via the objective lens and the optical element, generates interference light between returning light of the measurement light and the reference light, and detects the generated interference light.

A therapeutic method can include receiving an initial astigmatism condition of an eye; receiving a target final astigmatism condition of the eye; generating, based on the initial and target final astigmatism conditions, an eye incision pattern by iterating through a plurality of potential corrective combinations; and cutting the eye based on the eye incision pattern. Each of the potential corrective combinations can be defined by one or more of: an intraocular lens selected from a plurality of intraocular lens options, an access incision selected from a plurality of access incision options, and an arcuate incision selected from a plurality of arcuate incision options.

Method, system and computer program for measuring light diffusion in the eyeball or in the ocular region.

The method comprises: projecting a punctiform light beam onto the retina; correcting low-order ocular aberrations of the eye; capturing and recording an image of the retinal plane formed after reflection of the punctiform light beam on the retina and a double passage through the ocular media of the eye; and at the same time as capturing the image of the retinal plane, performing a high- and low-order ocular aberration measurement in the plane of the pupil and performing a light diffusion measurement, combining ocular aberration measurement information with information on the image of the retinal plane.

The system and the computer program are adapted for implementing the method.

A system and method for measuring a characteristic of an eye of a subject receive data pertaining to the subject; assign the subject to an assigned age category based on the data pertaining to the subject; adjust a brightness level of a fixation target according to the assigned age category for the subject; provide the fixation target for a subject to view; and objectively measure at least one characteristic of the eye of the subject while the subject views the fixation target at the adjusted brightness level.

To realize a toric ophthalmic lens including an edge that makes it possible to design a lens contributing to secondary cataract prevention without deteriorating a degree of freedom of lens design. The toric ophthalmic lens is a toric ophthalmic lens in which, in a top view of an optical portion, a substantially flat portion having a substantially fixed edge thickness of the optical portion is provided to overlap a steep meridian of a toric surface of the optical portion.

An ophthalmologic device includes: a visual target presenting unit configured to present a common visual target to be viewed with both subject's eyes; a presenting distance changing unit configured to change a presenting distance of the visual target presented by the visual target presenting unit from a predetermined far vision distance to a predetermined near vision distance; an ocular characteristic acquiring unit configured to objectively acquire an optical characteristic of the subject's eyes; an addition power adding unit configured to add the addition power to the both subject's eyes; and a control unit configured to cause the presenting distance changing unit to change the presenting distance and the ocular characteristic acquiring unit to continuously acquire the optical characteristic, in a state in which an addition power is added to the both subject's eyes by the addition power adding unit.

A laser system that includes a laser source emitting a laser beam along an axis and a keratometer. The keratometer includes a first set of individual light sources that are equally spaced from one another along a first ring and that direct a first light toward an eye and a second set of individual light sources that are equally spaced from another along a second ring and direct a second light toward the eye, wherein the first ring and said second ring are co-planar and concentric with one another about the axis. The laser system includes a telecentric lens that receives the first light and second light reflected off of the eye and a detector that receives light from the telecentric lens and forms an image. The laser system also includes a processor that receives signals from said detector representative of the image and determines an astigmatism axis of the eye based on the signals.
