Non-linear interaction between the electromagnetic fields (EMF) occurs whenvacuum polarization in quantum electrodynamics (QED) happens. The field ofnon-linear electrodynamics, which may result from this interaction, could haveimportant effects on black hole physics. This paper considers theasymptotically flat black hole solution in Einstein-nonlinear electrodynamics(NLE) fields. We study the effect of the NLE parameters on the black holedeflection angle using the Gauss-Bonnet theorem in weak field limits, shadowcast using the null geodesics method, and thin accretion disk using theNovikov-Thorne model. In particular, we studied the time-averaged energy flux,the disk temperature, the differential luminosity, the different emissionprofiles, and infalling spherical accretion. Then we show how the physicalquantities depend on $\beta$ and $C$ parameters of NLE and provide someconstraints on the NLE parameters using the observations of M87* and Sgr A*from EHT.
