    Abstract: A device (1) for cutting an ophthalmic lens (L1) to be mounted onto a spectacle frame, includes: elements (10) for locking and rotating the ophthalmic lens about a locking axis (A1); a tool holder which supports at least one first tool (60) rotatable about a rotational axis (A2) and a second tool (80) rotatable about a finishing axis (A6) and which has a spacing mobility (ESC) for the spacing apart thereof from the locking axis, a shifting mobility (TRA) for the axial positioning thereof along the locking axis, and a pivoting mobility (PIV) for adjusting the orientation of the rotational axis relative to the locking axis; and elements for controlling the three mobilities of the tool holder. The rotational and finishing axes are separate from one another.

    Abstract: An optometry device for testing an individual's eye (E) comprises an imaging module (10) adapted to produce a first image at a variable distance for the individual's eye (E), a beam splitter (26) arranged to combine the first image and a second image for the individual's eye (E), and a screen (22) facing the beam splitter (26). A mirror (24) is arranged in combination with the screen (22) to produce the second image to be visible by the individual's eye via the beam splitter (26).

    Abstract: An optical device including a lens and a control member configured such that motion of the control member produces a change in the optical power provided along an optical axis of the lens. The optical device further includes a framework, a motor and a driving member. The motor includes an output shaft rotatively coupled to said driving member. The motor and the control member are mounted in the framework such that the driving member and the control member mechanically cooperate. The driving member is rotatably mounted in the framework. The optical device comprises biasing means for maintaining the driving member in a predetermined axial position along the output shaft axis and relative to the framework. This optical device can be used in an optometric equipment.

    Abstract: A binocular optoelectronic apparatus for screening defects in the sight and for measuring the visual acuity of a user, includes a casing having a right-hand first aperture and a left-hand first aperture, which apertures are intended to be placed facing the right eye and the left eye of a user facing in a first gaze direction, respectively. This apparatus includes: a touchscreen placed so that a first zone of the touchscreen is located in the interior of the casing and a second zone of the touchscreen is accessible from the exterior of the casing; electronic elements suitable for displaying a plurality of optotypes on a first portion of the first zone; and an optical system configured to form a right-hand first image of the first portion of the first zone in the direction of the first right-hand aperture at a first vision distance along a first optical path.
