摘要: A method for determining a progressive ophthalmic lens comprising near and far vision area, main meridian separating the into nasal temporal comprising: first second surface of lens; to provide, in combination with surface, correcting properties; spherical area on having constant sphere value including diopter measurement position, wherein position have substantially same mean value; reduce distortion by defining toric extending outside at least one characteristics are related astigmatism.
