The cross section of photon-photon scattering at low energy can be written as $\\displaystyle{{d\\sigma\\over d\\Omega} \\simeq {\\alpha^4\\over (12\\pi)^2 \\omega^2} (3+2\\cos^2\\theta +\\cos^4\\theta)}$ with $\\omega$ the energy of photon. The magnitude of the cross section at $\\omega \\simeq 1$ eV should be $10^{37}$ times larger than the prediction of Heisenberg and Euler who calculated the photon scattering by the classical picture of field theory.
