Question about EFIELD in VASP

Hi,
I found the unit of EFIELD in VASP is eV/A;however,in many papers,the the unit of EFIELD is V/A. What is the difference between the two units?
In addition.can VASP be used to calculate polarization change of a system ?and,how to set in INCAR ?

Cf. e.g. the tread:

Thank you for your reply，But I think E = F / q
The force on an electron charge （-e）
eV/A = -V/A instead of
eV/A = V/A.
right?
