Title
(EN) ADJUSTABLE FOCUS LENSES
(FR) LENTILLES A FOCALISATION REGLABLE
Abstract
(EN)
A lens unit with two lens elements each having special surfaces such that an adjustment of the position of one of the two lens elements relative to the other in a direction generally perpendicular to a viewing direction changes the focusing power of the lens unit. In preferred embodiments two lens units are mounted in a frame to provide eyeglasses with adjustable focus. Several frame designs are described. In preferred embodiments two lens units, each lens unit having two lens elements are mounted in a frame to provide eyeglasses with adjustable focus. Several designs are described. Some designs provide for movement side to side movement of the lens elements relative to each other. In other designs the relative motion is up and down. A simple technique is a thumbscrew adjustment that is operated by the wearer. Another design is based on finger force against a friction force. In some preferred embodiments separate frames holding the lens elements pivot about pivot points on the earpiece of a support frame. In other designs two rear lens elements are mounted in a support frame and the front lens elements are mounted in a separate frame that pivots about a point on the earpiece of the support frame. Another design includes a torsion bar assures that the movements of each lens element in one of the lens units is the same as the movements of the lens elements in the other lens unit. Techniques for automatic focusing of the lenses are also disclosed. Techniques for automatic focusing of the lenses are also disclosed.

L'invention concerne une unité lentille qui comprend deux éléments lentilles possédant chacun des surfaces spéciales telles qu'un ajustement de la position de l'un des deux éléments lentilles par rapport à l'autre dans une direction généralement perpendiculaire à une direction de visualisation modifie la puissance de focalisation de l'unité lentille. Dans des modes de réalisation préférés, on fixe deux unités lentilles dans une monture afin d'obtenir des lunettes à focalisation réglable. L'invention se rapporte à plusieurs modèles de montures. Dans des modes de réalisation préférés, on monte deux unités lentilles, chaque unité lentille comprenant deux éléments lentilles, dans une monture afin d'obtenir des lunettes à focalisation réglable. L'invention porte sur divers modèles. Certains modèles de l'invention permettent un mouvement latéral des éléments lentilles l'un par rapport à l'autre. Dans d'autres modèles, le mouvement relatif s'effectue de haut en bas. L'invention peut faire appel à une technique simple de réglage par vis de serrage à main commandée par l'utilisateur. Dans un autre modèle, on exploite la force d'un doigt s'exerçant contre une force de frottement. Dans certains modes de réalisation préférés, des montures séparées maintenant les éléments lentilles pivotent autour de points de pivotement sur la branche de la monture de support. Dans d'autres modèles, on monte deux éléments lentilles arrière dans une monture de support et l'on monte les éléments lentilles avant dans une monture séparée qui pivote autour d'un point sur la branche de la monture de support. Un autre modèle comprend une barre de torsion qui garantit que chaque élément lentille de l'une des unités lentilles effectue les mêmes mouvements que ceux des éléments lentilles de l'autre unité lentille. L'invention concerne également des procédés de focalisation automatique des lentilles.
