While standing underwater at night, I noticed a pattern all around me that would slide left and right as I rotated in place. The pattern appears in daytime as well, but is more noticeable at night.

That happens because you're in very shallow water, and is intended. Try again in something deeper.
Added two screenshots of my view at the bottom of a deep ocean, one with night vision.
