1. A system for measuring the refractive properties of the eyes of a subject, said system comprising:

  • an optical system for directing illuminating beams into the eyes of the subject;

    a phoropter comprising separate phoropter assemblies disposed in front of each of the eyes of the subject, such that the vision of each of the eyes of the subject can be subjectively corrected;

    at least one of a lateral adjustment mechanism for the phoropter assemblies, or an angular adjustment mechanism for the angular alignment between the phoropter assemblies for each of the eyes of said subject, anda wavefront analyzer for determining the aberrations of each of the eyes of the subject, said wavefront analyzers being disposed such that light emitted from each of said eyes enters their associated wavefront analyzers after traversing their associated phoropter assemblies,wherein at least one of said phoropter adjustment mechanisms is adapted to enable said illuminating beams to be directed into the eyes of the subject along beam paths not coincident with the optical axes of the eyes of the subject.
