What kind of vision do you need?

Far vision

Near vision

Progressive vision

Simple vision lenses correct myopia, a very common eye condition that causes blurred vision at a distance.
Presbyopia and farsightedness cause blurred near vision, and are also corrected by single vision lenses.
They have three vision zones (far, intermediate and near) and use state-of-the-art technology designed to ensure a gradual transition between these different distances.
