Abstract
A process for determining a pair of personalized progressive ophthalmic lenses. and a computer program product associated to these processes. Right-handed persons and left-handed persons behave very differently when executing certain near vision tasks, such as writing on a sheet of paper. However, current lens designs do not take into account these behavior differences. The comfort of wearing a pair of ophthalmic lenses can be improved for the wearer for whom the lenses are intended by adapting his near vision according to his handedness.
