However, these phenomena remain largely unexplored beyond classical Brewster\u2010angle configurations. In this work, we establish a unified theoretical framework to describe topological transitions\u2014from an ideal vortex to a deformed off\u2010axis vortex\u2014near reflection singularities and provide experimental validation of the predictions. Through a full\u2010wave model, we demonstrate that the transition is governed by three independent degrees of freedom: the incident angle, the incident polarization state, and the reflected polarization state. This triple\u2010control mechanism enables precise manipulation of vortex deformation and lateral shifting. Furthermore, we extend this approach to multilayer systems by designing a PT\u2010symmetric bilayer structure satisfying\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>s<\/jats:italic>\n                    <\/jats:sub>\n                    \u00a0=\u00a00.
