  Every astrophysical object (dark or not) is a gravitational lens, as well as
a receiver/observer of the light from sources lensed by other objects in its
neighborhood. For a given pair of source and lens, there is a thin on-axis
tubelike volume behind the lens in which the radiation flux from the source is
greatly increased due to gravitational lensing. Any objects which pass through
such a thin tube or beam will experience strong bursts of radiation, i.e.,
Extreme Gravitational Lensing Events (EGLEs). We have studied the physics and
statistics of EGLEs. EGLEs may have interesting astrophysical effects, such as
the destruction of dust grains, ignition of masers, etc. Here we illustrate the
possible astrophysical effects of EGLEs with one specific example, the
destruction of dust grains in globular clusters.
