A method and system for treating Presbyopia and pre-Presbyopia are provided that do not compromise the wearer's intermediate or distance vision. The system is a lens and a lens series, wherein the power profiles of the lenses are tailored to provide an amount of positive ADD power in the near vision zone that is slightly less than that which is normally required for near vision accommodation, while also providing an amount of negative spherical aberration in the peripheral optical zone. The dynamic ocular factors of the wearer's eye work in conjunction with the positive ADD power provided by the central optical zone and with the effective ADD gained from the negative spherical aberration provided by the peripheral optical zone to induce a minimally discernible amount of blur that is tuned to maximize the wearer's depth of focus.

L'invention concerne un procédé et un système permettant de traiter la presbytie et la prépresbytie, qui ne compromet pas la vision intermédiaire ou éloignée du porteur. Le système est une lentille et une série de lentilles, les profils de puissance des lentilles étant conçus pour transmettre une quantité de puissance positive ADD dans la zone de vision proche qui est légèrement inférieure à celle normalement exigée pour l'accommodation en vision de près, tout en transmettant également une quantité d'aberration sphérique négative dans la zone optique périphérique. Les facteurs oculaires dynamiques de l'il du porteur travaillent en association avec la puissance positive ADD transmise par la zone optique centrale et avec l'ADD efficace obtenue par l'aberration sphérique négative transmise par la zone optique périphérique pour induire une quantité de flou minimalement perceptible qui est ajustée pour maximiser la profondeur de champ du porteur.
