Material Getting Weird Artefacts as it moves away from Grid

The Eye Material on my Character starts to have weird artifacts as it moves away from the Grid. It works as intended at the center. Since I use large sets for Animating the Shots, the character will naturally move away from the Center for certain shots. This primarily seems like a problem in Cycles but in some characters it also happens on Eevee.

In the Link below you will find the same question I posted a while back on Stackexchange but it contains the blend file and images. For some reason the images are not uploading here.
