AB  - The present study delves into the gravitational lensing phenomena in the weak field limit of a charged black hole in the mimetic Euler-Heisenberg theory. The deflection angle of light is computed for the specified asymptotically flat spacetime assuming that the observer and the light source are both located at finite distances from the lens using the Gauss-Bonnet theorem. Additionally, the Einstein ring radius is analytically derived as a direct implementation of the deflection angle. The relevant influence of the Euler-Heisenberg parameter and the charge parameter on the Einstein ring radius is briefly discussed. We also investigate the observational implications of lensing in the weak gravitational limit of the black hole. The magnification and distortion parameter are also analyzed in this manuscript. Furthermore, the time delay of light due to gravitational lensing is also briefly discussed. Our study reveals the significant influence of the model parameters of the specified black hole on the gravitational lensing signatures.
