Lensing statistics gives a method of testing the cosmological constant at intermediate redshifts---at low and high redshifts the possibilities for measuring $\lambda_{0}$ are limited and even at intermediate redshifts $\lambda_{0}$ often cancels out in observable relations---using well-understood lens theory and standard astrophysical assumptions
