摘要:
A device for measuring a subject's ocular parameters, in particular the interpupillary distance, comprises a front plate against which the face of the subject is placed, comprising two windows substantially corresponding to the lenses of a pair of eyeglasses. A lens is movable along its optical axis, which is perpendicular to the front plate, from an origin position near the front plate. A viewing eyepiece is disposed at the focus of the lens when in the origin position. A semi-reflecting mirror disposed at 45.degree. renders the eyepiece and a point source coincident, as far as the subject is concerned. Parallel to the semi-reflecting mirror, another mirror reflects an image of a cathode ray tube screen to the eyepiece through another lens. Adjustable calibrated voltage sources are used to produce coincidence of the reflections of the source on the corneas of the eyes of the subject and the luminous traces on the screen of the cathode ray tube, as seen by an operator looking through the eyepiece. These traces constitute graticules, and the voltages which generate them constitute basic measurements of the ocular parameters. The appropriate calculations are implemented by a microprocessor.

The peripheral edge of an ophthalmic lens is maintained in contact with a bevelling or grooving wheel while being rotated about an axis of the lens parallel to the axis of the bevelling wheel whereby a bevel or groove is formed in said peripheral edge. The ophthalmic lens is capable of relative axial displacement relative to said bevelling wheel. By way of a force or displacement sensor, the relative axial position of the ophthalmic lens with respect to the bevelling wheel can be made subject to the axial component of reaction forces generated between the lens and the bevelling wheel in their mutual contact zone.
