Problem with transferring UV map from one eye to another

Hi. After copying UV from one eye to another by selecting eyes - OBJECT - MAKE LINKS - TRANSFER UV MAPS eye from the right side has difference in mapping, you see where is the vertices some white lines.

why is it?

why not just duplicate the existing eye object.

sorry, problem is solved. I found that i made some changes to the shape of the second eye before transferring the UV from another eye :smiley:
