Abstract: A device and method for the controlled processing of at least one workpiece (1), comprising a workpiece carrier (2) on which at least one workpiece receptacle (2.1) is present remote from a rotary shaft (2.0), at least one processing unit (3) and at least one inspection unit (4), which are offset relative to the rotary shaft (2.0) by an angular distance (?n) from one another, are each arranged so that they can be adjusted and moved in a translational manner radially with respect to the rotary shaft (2.0), so that a processing beam (E) and an inspection beam (P), offset relative to one another by the angular distance (?n), describe the same spiral-shaped movement path (S) relative to the workpiece carrier (2), and the inspection results derived at an inspection point (PP) are used to control process parameters in order to change the effect of the processing beam (E).

Abstract: A long-range optical device has at least one optical channel which comprises a housing and an arrangement of optical elements. At least one of the optical elements is movable relative to the housing for image stabilization in the event of perturbing movements of the housing. The device further comprises a stabilization system for the at least one movable optical element, which has an eddy current damper for damping movements of the at least one movable element. The stabilization system, in the event of a displacement of the at least one movable optical element, generates a restoring force proportional to the displacement velocity of the at least one movable optical element. The eddy current damper comprises a magnet system and an eddy current carrier interacting therewith. The restoring force generated by the eddy current damper is dependent on the amplitude of the displacement of the at least one movable optical element.

Abstract: In a process for fitting a contact lens to a human eye, the geometry of the eyeball and the back surface geometry of the lens, and the required optical corrections for the distant and near vision of the eye to be corrected are determined. The measurement for fitting the contact lens takes place with a measuring lens that enables determination of relative pupil motion with respect to a reference system on or near the eye on changing from far vision to near vision. The measuring lens to be used for this measurement process has a substantially spherical lens body that has a substantially convex outer surface and a substantially concave inner surface. This measuring lens preferably serves for fitting multifocal contact lenses. To facilitate the measuring process, arrangements for determining the relative movement of a human pupil with respect to the surface of the measuring lens is provided on the measuring lens.

Abstract: A multifocal contact lens has a substantially spherical lens body that has a substantially convex outer surface, a substantially concave inner surface, and an optical central point, with a horizontal and a vertical axis that intersect in the optical central point. These axes are horizontal and vertical in the sense that the lens being worn on a human eye is in a usually upright position. The lens has a centrally arranged optical zone, a lens outer region, and an rim region, and at least two thickened regions arranged on the outer lens region, between the optical zone and the rim region and laterally of the vertical mid-axis, for setting a given orientation of the contact lens relative to the human eye. A prescribed near vision value, at least in a lower visual region, and a prescribed far vision value in an upper visual region are distributed on the surface of the lens body.

Abstract: Contact lenses having position stabilization are utilized in order to fix the position of the contact lens on the cornea of the eye of a person wearing the lens. For this purpose, thickened regions for adjusting a specific orientation relative to the eye of the wearer are provided on the convex outer surface of the contact lens outside of the optical zone. A reliable position stabilization of a contact lens on the eye is achieved in that at least two thickened regions are provided laterally of the vertical center axis. These thickened regions extend essentially below a horizontal center axis between the optical zone and the edge region and it is very advantageous if these thickened regions lie at least at one point on the lower eyelid when the eye is open. In this way, a rotation of the contact lens is avoided when the eye is open. Furthermore, it is advantageous when the contact of the thickened regions on the lower eyelid is maintained.
