Abstract

Merté (1950) described lens forms that correct oblique astigmatism at all ocular rotations. The front surfaces of all lenses were flat, and the back surfaces were made aspherical as conicoids. Merté did not provide a derivation of his formulae for the appropriate conicoidal surfaces. We show that Merté's formula is correct and describe the nature of appropriate conicoidal back surfaces of spectacle lenses.

摘要

默特（1950年）描述了在所有眼球转动时矫正斜散光的镜片形式。所有镜片的前表面都是平的，而后表面制成非球面的二次曲面。默特没有给出他关于合适二次曲面公式的推导过程。我们证明了默特的公式是正确的，并描述了合适的眼镜镜片二次曲面后表面的性质。
