  We consider an astrophysical system with a population of sources and a
population of lenses. For each pair of source and lens, there is a thin on-axis
tube-like volume behind the lens in which the radiation flux from the source is
greatly increased due to gravitational lensing. Any objects (such as dust
grains) which pass through such a thin tube will experience strong bursts of
radiation, i.e., Extreme Gravitational Lensing Events (EGLE). We study the
physics and statistics of EGLE for the case in which the shear is larger or
comparable to the finite source size. We find that the presence of shear has
only a small effect on the EGLE statistics.
