In poetry:

And now a writhing worm am I,
Beneath a doomed love’s lensing eye,
Let me but stagger, far from sight,
To hide my anguish, in the night.

The fairies dance each full-mooned night,
Would we but doff our lenses strong,
And trust our wiser eyes' delight.

In science:

Finally, assuming we are indeed seeing lensing, we have made an initial attempt to deduce the mass of the ob jects doing the lensing and the mass of the group in which they reside.
Observations of cluster substructure using weakly lensed sextupole moments
The mass of the group is easier to estimate than the mass of the lensing ob jects themselves, in that the former depends only on the i) the size of the observed group, ii) the fraction of background galaxies that are lensed, and iii) the average induced quadrupole moment.
Observations of cluster substructure using weakly lensed sextupole moments
One main conclusion from this study was that the extrapolated lensing rate could not be explained by the visible matter; however, one cannot determine if the increased rate is a result of lensing dark matter in the disk or halo.
Dark Matter in the Local Galactic Disk
Several known lensing degeneracies are summarized in Saha (2000), along with a derivation of the arrival-time interpretation above, but apart from steepness and the obvious monopole degeneracy, none of them are applicable in the context of lensed quasars.
Gravitational lensing model degeneracies: Is steepness all-important?
In 8 lenses we let the models be asymmetric, either because secondary lensing galaxies have been identified or because symmetric and asymmetric assumptions led to very different mass distributions.
Gravitational lensing model degeneracies: Is steepness all-important?
De flectors in motion have been considered several times in gravitational lensing analyses, the main motivation being that most astrophysical lenses are actually not at rest in the observer’s frame of reference.
On aberration in gravitational lensing
Furthermore, under an astrophysical point of view, the scenario of a static lens and a moving observer can often provide a more immediate representation of the real lensing system, as for the case of lensing by the supermassive black hole in the Galactic center.
On aberration in gravitational lensing
The comparison between lensing mass and dynamical mass is given in Table 2. (θ/θ0 ) is a measure of how close the lensing system is to the deep MOND or the Newtonian regime.

Finally, since the results of the paper are for generic general mappings, not just generic lensing maps, the findings are expected to be applicable not only to gravitational lensing, but to any system in which these singularities appear.

One of the key signatures of gravitational lensing is the occurrence of multiple images of lensed sources.

These data have enabled the confirmation of an additional 15 grade ‘A’ (certain) lens systems, bringing the number of SLACS grade ‘A’ lenses to 85; including 13 grade ‘B’ (likely) systems, SLACS has identified nearly 100 lenses and lens candidates.

The background source is modeled as single or multiple Gaussian or Sersic ellipsoid components which are lensed by ray-tracing through the SIE mass model of the lens; this lensed source is fit to the observed images in the lens galaxy-subtracted frame.
