A device of the present invention includes: a means for photograghing an anterior eye segment of a subject; a first display means for displaying an image of the anterior eye segment; means for processing the displayed image to detect each position of a pupil and a contact lens; a calculating means for obtaining the relationship of relative positions between them by calculating; and a second display means for displaying the obtained relationship of the relative positions. If the device is used for inspecting a condition for putting on of the contact lens, in particular, it is possible to measure the relationship of the relative positions between the contact lens at the time of being put on and the pupil.
Un dispositif de mesure et de contrôle ophtalmologique comprend un organe permettant de prendre une image de la partie antérieure de l'oeil d'un sujet, un premier organe d'affichage permettant la visualisation de l'image de la partie antérieure, un organe de traitement de l'image permettant de détecter les positions relatives de la pupille et de la lentille de contact du sujet, un organe de calcul permettant, par calcul, de déterminer les relations positionnelles entre les positions, et un second organe d'affichage permettant d'afficher les relations ainsi obtenues. Lorsque le dispositif sert à contrôler la condition de port d'une lentille de contact, il donne très précisément la relation positionnelle relative entre la lentille de contact et la pupille portant la lentille de contact.
