Morphology

objective = object (transparent) = object + ive

The sense 'lens nearest the object' is directly related to 'object' + '-ive' meaning 'relating to the object', so learners can readily infer the sense.

Etymology

Objective for a microscope lens comes from the idea of the object 'thing' you look at, so the objective lens is the part closest to the 'object'. That is why the objective lens looks directly at the thing you want to see.
