Abstract:
(EN) The invention relates to devices and to a computer program by means of which the spherocylindrical refraction of an eye can be determined. According to the invention, a component (10) having adjustable optics (13) is provided, the refractive power of which can be adjusted via a refractive power adjustment device (14). The spherocylindrical refraction is then determined from the adjustment of the refractive power adjustment device (14) at different orientations of a preferred direction of the optics (10) or a preferred direction of eye test characters.
(FR) L'invention concerne des dispositifs ainsi qu'un programme informatique permettant de déterminer la réfraction sphéro-cylindrique d'un oeil. A cet effet, on fournit un composant (10) pourvu d'une optique réglable (13) dont la puissance optique peut être réglée au moyen d’un dispositif de réglage de la puissance optique (14). La réfraction sphéro-cylindrique est déterminée à partir du réglage du dispositif de réglage de la puissance optique (14) pour différentes orientations d'une direction préférentielle de l’optique (10) ou d’une direction préférentielle d’optotypes.
(DE) Es werden Vorrichtungen sowie ein Computerprogramm offenbart, mit welchem die spharozylindrische Refraktion eines Auges bestimmt werden kann. Hierzu wird eine Komponente (10) mit einer einstellbaren Optik (13) bereitgestellt, welche über eine Brechkrafteinstelleinrichtung (14) hinsichtlich ihrer Brechkraft verstellt werden kann. Aus der Einstellung der Brechkrafteinstelleinrichtung (14) bei verschiedenen Orientierungen einer Vorzugsrichtung der Optik (10) oder einer Vorzugsrichtung von Sehzeichen wird dann die spharozylindrische Refraktion bestimmt.
