1. A device for selecting contact lenses within a cabinet arranged to receive a plurality of contact lenses, the device comprising:
means for storing data based on measurements from an auto refractometer; and data processor means associated with a calculation module for identifying a contact lens on the basis firstly of data from the auto refractometer as previously stored in the storage means, and secondly of additional data relating to the contact lens that is to be identified and that was previously input by the user, said data processor means associated with said calculation module also being arranged to identify the location of the lens within the cabinet, wherein the data processor means associated with the calculation module are also arranged to determine the characteristics of a new lens from the characteristics of a previously identified lens and from additional data measured by the user on a patient wearing said previously identified lens, the additional data comprising at least a measurement of over refraction, said data processor means associated with said calculation module also being arranged to identify the location of this new lens within the cabinet, and wherein when said previously identified lens is a spherical lens, the data processor means associated with the calculation module are arranged to determine the sphere, the cylinder, and the axis of the new lens on the basis of the characteristics of the previously identified lens and of a measurement of over refraction performed on the patient wearing said previously identified lens. |
