Abstract By undergoing Varma's phenomenological constraints a calculation of the optical conductivity σ(ω) in polaron model has been performed in order to interpret the infrared absorption features in high T_c superconductors. The temperature and phonon relaxation effects have been included. The agreement between our theoretical results and experiments is satisfactory.
