Persona PRO Sigma is the premium progressive lens that provides the user with improved binocular vision, especially in the intermediate and near areas.

Persona PRO Sigma lens is optimized con­sidering the natural convergence of the eyes when looking at a nearby object.

Positioning the near area in accordance with this convergence improves the user’s vision because it increases the binocular field of vision. However, this generates a non-homogeneous distribution of astigmatism.
