Title: Bernard Cousyn: Innovator in Ophthalmic Technology
Introduction
Bernard Cousyn is a notable inventor based in Vincennes, France. He has made significant contributions to the field of ophthalmic technology, holding 2 patents that showcase his innovative approach to lens manufacturing and ocular measurement devices.
Latest Patents
One of Cousyn's latest patents is a grinding machine for forming the edge of an ophthalmic lens. This method involves rotating the lens about its own axis while simultaneously displacing it parallel to its axis based on its angle of rotation. The edge of the lens remains in contact with a grinding wheel, ensuring that the point of contact follows a specific path. This path is determined by comparing predetermined paths with two reference paths obtained through prior plotting operations. This innovative method allows for the automatic trimming and bevelling of ophthalmic lenses.
Another significant patent is an ocular parameter measuring device. This device features a conventional optical design, including a front panel, a convergent lens, and a light source. The operator can measure ocular parameters by using a control keyboard to send address signals to liquid crystal matrixes, which display vertical or horizontal lines for measuring interpupillary distance or centering lenses in frames.
