  • Patent number: 6355124
    Abstract: A method and apparatus for the lamination of two lens blanks to form an ophthalmic lens comprise: a) providing a first ophthalmic lens blanks having two major surfaces thereon; b) applying a hardenable liquid adhesive to less than an entire one of said at least two major surfaces of said first ophthalmic lens blank; c) placing a second ophthalmic lens blank into contact with the hardenable liquid adhesive, forming an association of two lens blanks with the hardenable liquid adhesive between the two lens blanks; d) rotating said association of two lens blanks to assist in spreading the hardenable liquid adhesive; and e) after at least some of said hardenable liquid adhesive has spread, hardening said hardenable liquid adhesive to laminate the two lens blanks into a laminated ophthalmic lens. This method provides a relatively automated process and apparatus for performing that automated process for the lamination of ophthalmic lenses.

  • Publication number: 20010038494
    Abstract: A polymeric front optical element blank is provided which may be laminated to a rear optical element blank. The polymeric front blank comprises an optical element having an exterior convex surface and an interior concave surface, with an edge between the exterior convex surface and the interior concave surface. The optical is provided with at least two projections which extend away from and higher than the edge on a side of the optical element having the concave surface. These projections assist in aligning an back optical element during lamination so that the two lenses will not move out of optical registry during lamination, especially where centrifugal forces are used to spread an adhesive between the front and rear lenses. It is preferred that there are at least three projections extending away from and higher than the edge on a side of the optical element having the concave surface.
