The invention relates to a method for determining at least one parameter of two eyes (10I 10r) of a test person (31) the method comprising the following steps: optically capturing of a first eye (10I 10r) of the two eyes (10I 10r) by means of a first capturing unit (3I 3r) optically capturing the second eye (10r 10I) of the two eyes (10I 10r) by means of a second capturing unit (3r 3I) transmitting first signals concerning the captured first eye (10I 10r) from the first capturing unit (3I 3r) to an analysis unit (27) and transmitting second signals concerning the captured second eye (10r 10I) from the second capturing unit (3r 3I) to the analysis unit (27) determining the at least one parameter of the two eyes (10l 10r) on the basis of the transmitted first and second signals in the analysis unit (27) characterized by the following step: setting a first data rate for the first signals and a second data rate for the second signals wherein the first and the second data rate differ from each other and wherein the transmitting of the first signals is effected at a first data rate and the transmitting of the second signals is effected at a second data rate.
