Abstract
The invention relates to a method for producing a novel progressive glasses lens intended for a presbyopic wearer, which takes into account the postural habits of the wearer, acquired through prior conditions of ophthalmic correction. A design for the novel progressive lens is established by modifying a reference lens in compliance with an aptitude of the wearer to modify his/her postural habits. To this end, variations in a postural parameter are determined using measurements of said parameter, which are carried out on the wearer. The invention enables the reduction of a period of habituation by the wearer to the novel progressive glasses lens.
