Collection of ophthalmic lens pairs and ophthalmic lenses having residual reflections exhibiting colors of different intensity

摘要

Each lens of a pair of lenses is provided on at least one of its faces with an antireflection coating having a luminous reflection factor R_v that is 2.5% or less, having residual reflections exhibiting the same perceived color, the hue angle (h) for the antireflection coating of one lens varying by not more than 60° as compared to the antireflection coating of the other lens, and: the antireflection coating of one of the lens having an intensely colored residual reflection, a mean reflection factor R_m 1 >=1.20% and a chroma value C* 1 >=15, the antireflection coating of the second lens having a weakly colored residual reflection, a mean reflection factor R_m 2 <=1.65% and a chroma value C* 2 <=15, AND |R_m 1 -R_m 2 |<=2.2% and C* 1 -C* 2 >5. The invention can be applied to spectacle glasses.
