A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfering surface that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.

There is provided an eyeglass lens processing apparatus including a first rotational shaft which holds and rotates an eyeglass lens, a finishing tool, a chamfering tool which performs chamfering on an angular portion of an edge of the eyeglass lens, a second rotational shaft to which the chamfering tool is attached, an adjustment unit which adjusts a relative positional relationship between the first rotational shaft and the second rotational shaft, a chamfering angle setting portion which sets a chamfering angle formed between a rotational center axis of the first rotational shaft and a processing tool surface, an edge information acquisition portion which acquires information regarding an edge surface shape of the eyeglass lens, an angle correction portion which corrects the chamfering angle based on the information regarding the edge surface shape, and a control portion which controls the adjustment unit and performs chamfering based on the corrected chamfering angle.

Optical articles and methods of manufacturing the same are disclosed herein. In one aspect, the methods and optical articles formed include light-blocking compositions applied to optical substrates in accordance with the optical properties of the optical substrate. In another aspect, a method is disclosed in which the light-absorbing compositions are printed onto the optical substrate in the shape and size of the final lens that is to be formed from the optical substrate. In another aspect, the methods and optical articles utilize at least two different light-blocking compositions to achieve desired functionality of the optical article.

A method for producing an instruction for bevelling an ophthalmic lens, with a view to mounting same in a framework of a spectacle frame into which a bevelled display lens is initially fitted. The method includes the steps of: a) acquiring a correction parameter relative to the play between the framework and the display lens; b) capturing a surface image of the display lens previously removed from the framework; c) determining, on the surface image, an initial contour (C0) of the display lens; d) calculating a corrected contour (C1), by correcting the initial contour according to the correction parameter; and e) deriving the bevelling instruction according to the corrected contour.

An ophthalmic lens processing apparatus is provided that includes a housing, a support structure, and ophthalmic lens processing components configured to perform an ophthalmic process on an ophthalmic lens.
