The present invention relates to an optical lens comprising: a lens substrate comprising a cycloolefin copolymer; an optical film comprising a plurality of alternating first and second polymer layers; and an adhesive film disposed on the main surface of the lens substrate and adhering the optical film to the main surface of the lens substrate. The adhesive film is such that an average peel force separating the optical film from the lens substrate is greater than about 100 g/in while at least one outermost major surface of the optical film maintains an average displacement surface roughness Sa of less than about 10 nm and an inclination magnitude error of less than about 100 [mu] rad, and/or a lower spatial frequency tilt magnitude error and a higher spatial frequency tilt magnitude error both less than about 100 [mu] rad. 本发明涉及一种光学透镜，该光学透镜包括：包含环烯烃共聚物的透镜基片；包含多个交替的第一聚合物层和第二聚合物层的光学膜；以及设置在透镜基片的主表面上并将光学膜粘结至透镜基片的主表面的粘结膜。该粘结膜使得将光学膜与透镜基片分离的平均剥离力大于约100g/in，同时光学膜的至少一个最外主表面保持小于约10nm的平均位移表面粗糙度Sa和小于约100μrad的倾斜度大小误差，和/或均小于
