Patent number: 11782293Abstract: A progressive addition lens contains a plurality of microlenses for providing simultaneous myopic defocus. The microlenses are superimposed on a power variation surface of the lens, which includes a designated distance portion in the upper section of the lens adapted for distance vision and a fitting cross; a designated near portion located in the lower section of the lens, the near portion including a near reference point having a near dioptric power adapted for near vision; and a designated intermediate corridor extending between the designated distance portion and near portions. Microlenses are excluded from all areas of the surface located below a notional line extending from nasal to temporal limits of the lens at a vertical coordinate above the near reference point where the vertical coordinate lies at a distance above the near reference point with the distance being in a range between 1.5 mm and 3 mm.Type: GrantFiled: January 25, 2023Date of Patent: October 10, 2023Assignee: Carl Zeiss Vision International GmbHInventors: Saulius Raymond Varnas, Ray Steven Spratt, Timo Kratzer, Gerhard Kelch, Siegfried Wahl

Patent number: 8833936Abstract: A progressive ophthalmic lens element is disclosed. The progressive ophthalmic lens element includes an upper viewing zone, a lower viewing zone, a corridor, and a peripheral region disposed on each side of the lower viewing zone. The upper viewing zone includes a distance reference point (DRP) and a fitting cross, and provides a first refractive power for distance vision. The lower viewing zone, which is for near vision, provides an addition power relative to the first refractive power. The corridor connects the upper and lower zones and provides a refractive power varying from that of the upper viewing zone to that of the lower viewing zone. Each peripheral region includes a zone of positive power relative to the addition power which provides therein a positive refractive power relative to the refractive power of the lower viewing zone.Type: GrantFiled: November 9, 2010Date of Patent: September 16, 2014Assignee: Carl Zeiss Vision International GmbHInventor: Saulius Raymond Varnas

Patent number: 7980692Abstract: The present invention involves the prescribing and/or dispensing ophthalmic lenses, such as progressive addition lenses, for a wearer. In one form of the invention lens usage information is obtained from a wearer and entered into a programmed computer. The programmed computer processes the lens usage information to provide a separate weighted lifestyle score for each of one or more respective lifestyle score categories, such that each weighted lifestyle score is a function of a predetermined relationship between the respective lifestyle score category and at least ophthalmic lens design feature. The programmed computer then selects or designs an ophthalmic lens design using one or more of the weighted lifestyle scores such that the selected or designed ophthalmic lens has at least one lens design feature which has been customised using one or more of the weighted lifestyle scores.Type: GrantFiled: December 13, 2002Date of Patent: July 19, 2011Assignee: Carl Zeiss Vision Australia Holdings Ltd.Inventors: Scott Warren Fisher, Saulius Raymond Varnas, John Charles Bonnett
