We consider the bending of light by nonlinear electrodynamics when the magnetic field B exceeds the critical value B{sub c} = m{sup 2}c{sup 2}/e h-bar = 4.4 × 10{sup 9}T. Using the index of refraction derived from the analytic series representation in one-loop effective action of QED, we found the trajectory and the bending angle of light in geometric optics. The angle bent by ultra-strong magnetic field of magnetar was estimated and compared with the gravitational bending. The result may be useful in studying the lensing, birefringence, and other nonlinear quantum electrodynamic effects above B{sub c}.
