  We recently hypothesized that a distortion parameter exists such that its
signed sum for all images of singular gravitational lensing of a source
vanishes identically [K. S. Virbhadra, Phys. Rev. D {\bf 106}, 064038 (2022)].
We found a distortion parameter (the ratio of the tangential to radial
magnifications) that satisfied the hypothesis for the images of Schwarzschild
lensing with flying colors. We now show that another distortion parameter (the
difference of tangential and radial magnifications) also magnificently supports
our hypothesis when we perform computations with the primary-secondary and
relativistic images. The distortion parameters, which satisfy the aesthetically
appealing hypothesis, will likely aid in developing gravitational lensing
theory. Finally, we discuss the conservation of distortion of images in
gravitational lensing.
