Abstract
The invention relates to an ophthalmic lens comprising: a substrate having a given refractive index; and a coating that minimizes ultraviolet reflections, said coating having a given refractive index and being deposited on a rear face of the substrate. According to the invention, the thickness of the ultraviolet-reflection-minimizing coating is between I μm and approximately 200 μm and the refractive index of the ultraviolet-reflection-minimizing coating is at least 0.15 units less than the refractive index of the substrate. The invention also relates to a method for the production of such a lens.
