One of the main goals in double star research is the calculation of stellar masses. So a double star observer must study the nature of double stars rejecting optical pairs due to their lack of astrophysical interest. LIADA's Double Star Section used several professional methods to classify visual double stars in optical or physical pairs. In this work the Aitken criterion is explained in detail and its effectiveness studied. The Aitken criterion is possibly the easiest of several possible criteria to apply, but may be one of the less efficient and rigorous. This criterion is very useful when an observational program is being designed because it allows us to increase the astrophysical interest of stars to be included in the program.
