Description
I will discuss the theoretical modelling of line-of-sight perturbations in strong gravitational lensing. Two points will be highlighted:
1. There exists a notion of line-of-sight shear that is, in principle, distinguishable from properties of the main lens.
2. Distortions beyond convergence and shear (flexion, etc.) could play an important role.
