| titleOfInvention | Optical article comprising an antireflection coating having low reflection both in the ultraviolet region and in the visible region |
| abstract | The present invention relates to an ophthalmic lens with low reflection in the ultraviolet region, the ophthalmic lens comprises a transparent substrate having a front main surface and a back main surface, the back main surface is coated with a multi-layer anti-reflection coating, the multiple Layered antireflection coating comprising a stack of at least one layer having a refractive index higher than 1.6 and at least one layer having a refractive index lower than 1.55, wherein: for an angle of incidence of 35°, weighted by the function W(λ) The average reflection coefficient R UV on said back between 280nm and 380nm is lower than or equal to 5%, preferably lower than or equal to 4%, for an angle of incidence (θ) of 15°, the chromaticity of the reflected light C* is 4 or lower, preferably 3 or lower. |
