Do you mean codes like RB2883-S 718/31 58。16 135?! As far as I know, RB2883-S is the model number, while 718/31 the color code and finally 58/16/135 the size information.
The second set of digits is the sizing and lens class. Eg 58/16/135 means the width in mm of one of the lenses at its widest is 58mm. The bridge gap or the smallest gap between the two lenses is 16mm and the last digit is the temple width in mm. There may also be another number after this on the arm which is the lens code. 0 for does nothing up to 5 for NASA anti sun properties!
