Apparatus for forming optical lenses

摘要: Apparatus for and method of forming ophthalmic lenses and/or semi-finished lens blanks including those the eye contact type. The apparatus includes molds having cooperating first second members each which a longitudinal axis mold surface is symmetrical with respect to such axis. In one embodiment these or halves also include surfaces which, in operation cooperation selected material, both align respective axes axially position member thereby form desired cavity. Further, assembled an annular reservoir surrounds cavity defined by provided on members. This connected via restriction. this restriction aligning operation, holds volume material during polymer reaction, kept flowable state longer than arrangement permits transfer between curing. removing portions cast instances where removal either necessary expedient.
