(One of the things I like about The Expanse series is the creation of artificial gravity with thrust)

Something like in Interstellar.. Constant spinning.

A change in eye pressure, i.e., the shape of the eyes, is what changes vision from presbyopic to myopic. It has nothing to do with gravity.
My opinion is that lower than normal air-pressure is cause the eyeball to bulge leading to vision changes, for what it is worth.

Radiation would cause cataracts as it would cloud the lenses in the eyes.
