Abstract

This separator device (10) adapted to be positioned between two ophthalmic lenses comprises a housing having a top plate (12) and a bottom plate (14) parallel to the top plate (12). The top plate (12) has at least three circular apertures (16) and the bottom plate (14) has the same number of circular apertures (16) as the top plate (12) and at the same locations. The separator device (10) further comprises, at each of these locations, a ball (18) accommodated between the top and bottom plates (12, 14) in a pair of the apertures, the diameter of each aperture (16) being smaller than the diameter of each ball (18), each ball (18) protruding from the top and bottom plates (12, 14) through the apertures (16) and being able to rotate freely in the apertures (16) thanks to a predetermined clearance between each ball (18) and the edge of the apertures (16) accommodating the ball (18).
