when i mix red light and green light i get yellow light, but QED says that photons do not interact so why am i seeing yellow light, , I know they obey superposition , what does it mean for two photons two superimpose physically . how is the localized energy of the photons interacting .

What you see here is nothing to do with photons interacting.
It is a consequence of the way our eyes are sensitive to light.
The eye has 3 types colour receptor, each sensitive to a different overlapping range of wavelengths of visible light. All the various phenomena relating to the mixing and combining of colours depend on this.
Wiki has a good article on colour vision.
