To understand the incoherent optical response of La1 - x SrxMnO3 in the ferromagnetic and metallic phase near the metal-insulator transition, we examine the effects of eg-orbital degeneracy, Coulomb interactions, and Jahn-Teller distortions under the perfect polarization of spins, employing the Lanczös diagonalization method. Orbital fluctuations by the Coulomb interaction induce a large and broad structure of the incoherence and suppress Drude weight. The Jahn-Teller distortions work cooperatively to enhance this incoherence.
