Fine detail Distortion problem

So I know there is a term for this, but I can’t think of it. I have seen other models with fine details, but do not have this problem. The left image is a zoomed in screengrab of the detailed model and the right image is when the same model is pulled further away from the camera. I was wondering if any one knows how to avoid this spiral looking distortion that is present when you zoom out away from the model? Its driving me nuts! Thanks!!
