Title (EN) A SYSTEM FOR THE DETERMINATION, THE EVALUATION AND THE CONTROL OF THE REFRACTIVE AND ACCOMMODATIVE STATUS OF THE EYE
(FR) SYSTEME SERVANT A DETERMINER, A EVALUER ET A MODULER L'ETAT DE REFRACTION ET D'ACCOMMODATION DE L'OEIL
Abstract:
(EN) The system for the determination, the evaluation and the control of the refractive and accommodative status of the eye according to the present invention consists of: a scanner (AN) to be placed before the eye optically corrected or not, and completely or partially consisting of material polarizing the optical radiation, and divided into two parts with perpendicular polarization axis; an illuminated target (MR), completely or partially consisting of parts out of polarizing material, having the polarizing axis paralllel or perpendicular to each other, whereby said target may comprise means for moving said parts and for rotating said target onto the longitudinal axis.
(FR) Système servant à déterminer, à évaluer et à moduler l'état de réfraction et d'accommodation de l'oeil et consistant en un scanner (AN) conçu pour être placé devant l'oeil corrigé optiquement ou non et constitué, en totalité ou en partie, par un matériau de polarisation du rayonnement optique divisé en deux parties par un axe perpendiculaire de polarisation, ainsi qu'en une cible éclairée (MR) constituée totalement ou partiellement par des pièces en matériau de polarisation dont les axes de polarisation sont parallèles ou perpendiculaires les uns aux autres, ladite cible pouvant comporter des moyens servant à déplacer lesdites pièces et à faire tourner ladite cible sur l'axe de la longueur.
