Abstract
The invention relates to a progressive ophthalmic lens and to a method of producing one such lens. Variations in the optical power and the astigmatism of a progressive ophthalmic lens () result from (i) spherical and cylindrical variations in the anterior face () of the lens and (ii) variations in another physical unit of the lens. In this way, it is possible to customise the design of the progressive lens as a function of at least one behavioural characteristic of the lens wearer. Said customisation can be repeated by modulating the values of the physical unit between the different points of the lens. As a result, progressive lenses with different designs can be obtained from identical semi-finished lenses. The physical unit can comprise the sphere and the cylinder of the posterior face of the lens ().
