Abstract: This invention relates to an ophthalmic lens comprising a multilayered interferential coating and to a manufacturing method thereof.
The ophthalmic lens comprises:



an organic substrate having a front main face and a rear main face, and
a multilayered interferential coating (30) which is coated on at least one of the front main face and the rear main face,




According to the invention, the multilayered interferential coating (30) comprises at least one graphene layer (2) which has a uniform thickness of between 0,1 nm to 1 nm.
