Patent number: 10690939Abstract: A pair of spectacle progressive lenses configured for a wearer suffering from convergence insufficiency or imbalance. The lens of the pair which is dedicated to the dominant eye has inset values appropriate for matching convergence of the dominant eye, but the other lens of the pair, which is dedicated to the non-dominant eye, has inset values substantially equal to zero. Such lens pair helps in suppressing the non-dominant eye for intermediate and near vision tasks, therefore avoiding or limiting symptoms of convergence insufficiency.Type: GrantFiled: July 29, 2015Date of Patent: June 23, 2020Assignee: Essilor InternationalInventors: Berangere Granger, Sebastien Fricker

Patent number: 7740358Abstract: The invention relates to the determination of a pair of ophthalmic lenses, by measurement of the sagittal plane shift of the wearer for close vision with relation to the standard sagittal plane. Optimisation targets are then chosen as a function of the measured shift. The lenses are determined by optimisation with the chosen targets. Lenses are thus obtained with which the field of close vision is symmetrical with relation to the medial line as perceived by the wearer. A wearer with a displaced sagittal plane thus has a greater close vision field which facilitates binocular vision and increases acuity.Type: GrantFiled: August 5, 2005Date of Patent: June 22, 2010Assignee: Essilor International Compagnie Générale d'OptiqueInventors: Claude Pedrono, Bérangère Granger-Donetti
