Method for Determining at Least One Parameter of Two Eyes by Setting Data Rates and Optical Measuring Device

Abstract

The invention relates to a method for determining at least one parameter of two eyes (10l, 10r) of a test person (31), the method comprising the following steps:optically capturing of a first eye (10l; 10r) of the two eyes (10l, 10r) by means of a first capturing unit (3l; 3r);optically capturing the second eye (10r; 10l) of the two eyes (10l, 10r) by means of a second capturing unit (3r; 3l);transmitting first signals concerning the captured first eye (10l; 10r) from the first capturing unit (3l; 3r) to an analysis unit (27) and transmitting second sig-nals concerning the captured second eye (10r; 10l) from the second capturing unit (3r; 3l) 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 sec-ond 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.
