I will describe the great potential and possible limitations of using the bending of light by gravity (gravitational lensing) to constrain the mysterious dark energy which seems to dominate the contents of our Universe.

In particular we have to remove the blurring effects of our telescopes and the atmosphere to extreme precision, and account for possibly coherent distortions of galaxy shapes due to processes in galaxy formation.

I will discuss these issues in more detail and review some recent progress in tackling them, putting them into the context of the Dark Energy Survey and Large Synoptic Survey Telescope.
