Which physical change did Vincent NOT make to "become" Jerome?

In the context of Vincent's transformation into Jerome in the film "GATTACA," the physical changes he underwent were primarily designed to create a convincing appearance that aligned with societal expectations for genetically superior individuals. The correct answer indicates that Vincent did not change his eye shape as part of this transformation.

Vincent utilized eye contacts to alter his eye color, underwent significant changes to his hair, and resorted to methods such as surgical procedures or enhancements to increase his height. Eye shape, while a potential area of modification in genetic engineering, was not explicitly depicted as a change made by Vincent. This distinction is critical as it highlights not only the limitations of Vincent's modifications but also emphasizes the lengths to which he went to fit into a society that deemed genetic perfection as the standard. Thus, the lack of alteration in eye shape serves to exemplify the boundaries of Vincent's alterations and the broader themes of identity and societal pressure addressed in the film.
