Abstract
A progressive ophthalmic lens for the correction of myopia, that comprises an upper area in which the correction is adapted for peripheral vision of the wearer. Such a lens reduces the risk of long term worsening of myopia for the lens wearer by reducing the defocalisation of an image formed on the retina outside the foveolar area. Also disclosed is a method for making such a lens. According to one improvement, the correction of myopia for the peripheral vision in the upper area of the lens is further adjusted based on a tendency of the wearer to turn the eyes or the head for watching an eccentric object.
