Series of progressive ophthalmic lenses with low divergence and rotation of astigmatism
摘要:
An ophthalmic lens and a method for producing a progressive ophthalmic lens having at least one progressive surface, where by a calculation and optimization step in the production of the progressive lens is performed. The absolute value of the rotation |rot {right arrow over (A)}| and/or the divergence |div {right arrow over (A)}| of a vectorial astigmatism {right arrow over (A)} is as small as possible, and the absolute value |{right arrow over (A)}| of the vectorial astigmatism {right arrow over (A)} is proportional to the absolute value of an astigmatism in the use position of the progressive lens. The direction of the vectorial astigmatism {right arrow over (A)} is proportional to the axial position of an astigmatism in the use position of the progressive lens or a surface astigmatism of the at least one progressive surface of the progressive lens.
