Abstract
The present invention relates to an optical lens comprising a substrate with a front main face and with a rear main face, at least one of the main faces being coated with an antireflection coating, such that in the range [0°-50° ] of angles of incidence θ, the mean light reflection factor Rv(θ) on said coated main face presents a minimum value Rvfor an angle of incidence θ, comprised in the range [20°-50° ], and Rv/Rv(15°)<0.95, Rv(15°) being the mean light reflection factor for an angle of incidence θ of 15° on said coated main face. The optical lens is also useful to inhibit reflection of light in the ultraviolet range.
