It is shown that physical manifestations of any optical singularity are, in one way or another, related to a specific temporal behaviour of the field, no matter scalar or vector cases are realized. Polarization singularities of the vector field are associated with a presence or absence of angular momentum of electromagnetic field. In the vicinity of -point the orbital angular momentum is observed if the sings of topological charge of the vibration phase and the handedness factor are different.

Key words: polarization singularities, Poynting vector, angular momentum.
