The usual correction for this was “spotting” of the negative or print using primarily soft graphite pencils or special spotting paints applied with ultra fine brushes - obviously some photographers or their assistants were more skillful at this than others. This problem gradually went away after the turn of the century with the introduction of panchromatic films which were sensitive to all colors and faster as well.

Bob,
Great information... Thanks for explaining the cause of the brightness, and the process of “spotting” they used when enhancing the eyes... You are right, some photographers were much better skilled at this alteration than others...
Best, CSL
