If you use the iris to widen depth of field, the lens error doesn't matter as much. The limit is the pinhole camera which has no lens at all.

These headsets come with adjustable lens as well as adjustable irises; if your eye curvature was drifting a bit you’d correct with that. (And if it’s drifting a ton, increasing the depth of field is a poor fix indoors.) The dominant reason to have the iris while shooting is to help you keep three points at different distances in simultaneous focus: the target, far sight, and near sight.
