    Abstract: The invention relates to an optical lens comprising a substrate having a front main face and a rear main face, at least one main face of which being successively coated with a first high refractive index sheet which does not comprise any Ta2O5 layer, a second low refractive index sheet a third high refractive index sheet, a monolayer sub-layer having a thickness higher than or equal to 100 nm, and a multilayer interferential coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer. A mean reflection factor selected from Ruv for UV light, Rv for visible light and RsNIR for near infrared light is higher than or equal to 10-15% on at least one main face.
