Beschreibung
Zusammenfassung:	The invention relates to an ophthalmic lens having a substrate and a functional coating arranged as the outermost layer on the substrate, the functional coating imparting a tactile smoothness coefficient HGK of at most 0.28, preferably at most 0.25, and/or a tactile smoothness coefficient RHGK of at most 0.85, preferably at most 0.80, to the ophthalmic lens. The invention also relates to a measuring method for determining the smoothness of an ophthalmic lens represented by a tactile smoothness coefficient HGK and/or a tactile smoothness coefficient RHGK, and to a method for producing the ophthalmic lens. 本发明涉及一种眼镜镜片，该眼镜镜片具有基底和被布置为该基底上最外层的功能性涂层，其中该功能性涂层赋予眼镜镜片至多0.28、优选地至多0.25的触觉光滑度系数HGK和/或至多0.85、优选地至多0.80的触觉光滑度系数R_HGK。本发明还涉及一种用于确定由触觉光滑度系数HGK和/或触觉光滑度系数R_HGK表示的眼镜镜片的光滑度的测量方法，以及一种用于生产该眼镜镜片的方法。
