The influence of screening by confined free electrons on the exciton binding energy in the asymmetric double quantum well is calculated for var­ious values of applied electric field perpendicular to the layer plane. The dependence of the exciton binding energy on carrier concentration is found to be stronger for lower than for higher fields. The drop of field-dependent exciton energy is less remarkable at higher densities of free electrons. Calcu­lations were performed at 10 and 300 K, and up to densities of 10^{14} m^{-2} and 7 × 10^{14} m^{-2}, respectively.
