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 50nm, and a multilayer interferential coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer. The reflection performance on at least one main face is improved in scotopic conditions,fornear infrared light or for a wide range of angles of incidence.
