Abstract
In nonparaxial vector optical fields, the following topological events are shown to occur in apparent violation of charge conservation: as one translates the observation plane along a line of circular polarization (a line), the points on the line ( points) are seen to change not only the signs of their topological charges, but also their handedness, and, at turning points on the line, paired points with the same topological charge and opposite handedness are seen to nucleate. These counter-intuitive events cannot occur in paraxial fields.
