发明名称 JUNCTIONLESS OPHTHALMIC LENSES AND METHODS FOR MAKING SAME
摘要 Methods for producing a junctionless ophthalmic lens are provided. Additionally, ophthalmic lenses having junctionless, three dimensional surfaces, for example, asymmetrical anterior and/or posterior surfaces, as well as molding tools used in the production of such lenses are also provided. The method generally include providing sample data points to define a surface contour, and interpolating between these data points using an algorithm to produce a simulated three dimensional surface. The simulated three dimensional surface is used in producing an ophthalmic lens, for example in cast molding a contact lens (10) for use on a cornea (12) of a user.
