The ring itself implicitly ignores that "equipment" and chooses based on their individual willpower.
Better eyesight you mention is meaningless to the ring, as it can choose someone blind, you like to cite Moore, he came up with a Lantern who was blind so the ring channeled sound instead.
What mattered was the beings power of will, not physical attributes.
The ring adapts to the wielder physiology/equipment, big, small, is irrelevant, what it channels is their will.
Yes they use it differently as they should, and it manifests differently not only for different species, but for different individuals within a species.
But what it's recognizing in them and channeling is their will.
