Abstract

L'invention concerne une lentille optique de correction permettant une correction différentielle en vision de près et en vision de loin. Cette lentille comprend deux parois transparentes 1 et 2, entre lesquelles est disposé au moins un liquide transparent 4 d'indice optique déterminés; la paroi 1 est dotée d'une surépaisseur 5 qui forme au niveau du centre optique un volume capillaire dans lequel est aspiré le liquide lorsqu'on incline la lentille d'un angle déterminé. La lentille conforme à l'invention permet d'assurer une correction différentielle en l'absence de mouvement notable de l'oeil par rapport à celle-ci, par simple inclinaison de la tête ; elle peut notamment être utilisée en lentille souple de contact et être appliquée sur la cornée de l'oeil.
