Abstract: A method of coating an edge surface of an optical lens is provided. The method includes providing an optical lens comprising a first optical surface and an opposing second optical surface, wherein the first and the second optical surfaces are connected by an edge surface, disposing at least one temporary protective material on at least a portion of a perimeter portion of one or both of the first and the second optical surfaces abutting the edge surface, disposing at least one coating material on the edge surface of the optical lens to obtain at least one edge coating, and removing any excess coating material disposed on the at least one temporary protective material. An optical lens having at least one temporary protective material disposed on only at least a portion of a perimeter portion of one or both of the first and the second optical surfaces abutting the edge surface is also provided.

Abstract: An ophthalmic lens is provided. The ophthalmic lens includes a first optical surface, an opposing second optical surface and an edge surface connecting the first optical surface and the second optical surface, wherein the edge surface is planar. The ophthalmic lens further includes a first layer disposed on the edge surface, wherein the first layer includes a coating material effective to reduce a reflection caused by a profile of the edge surface, and wherein (a) the first layer defines a structural element for fastening the ophthalmic lens to an eyewear frame, or (b) the ophthalmic lens further includes a second layer disposed on the first layer, wherein the second layer defines a structural element for fastening the ophthalmic lens to an eyewear frame. A method of manufacturing the ophthalmic lens and an eyewear including the ophthalmic lens are also provided.

Abstract: This invention relates to an ophthalmic lens comprising a substrate with a front main face and with a rear main face. said rear main face being coated with a multilayered antireflective coating comprising a stack of at least two layers having a refractive index higher than or equal 1.55, defined as “HI layer” and at least two layers having a refractive index lower than 1.55, defined as LI layer, characterized in that said multilayered antireflective coating is such that: —the mean reflection factor in the near infrared (NIR) region RmNIR is lower than or equal to 8% at an angle of incidence of 35°, and 10—the mean reflection factor RUV (280-380 nm). weighted by the function W(λ) defined in the ISO 13666:1998 standard, is equal to or lower than 5% at an angle of incidence of 35°.
