Anti-reflective coatings work by cutting the unwanted reflection/scattering/diffusion of light (where it should not go) at each and any air-to-glass surface. So the coating has to be wehere it can do its work, i.e. on each and any air-to-glass surface. Perhaps even between glasses of different refraction indexes. A filter in front of the whole lens cannot do that.

Has anyone come out with a set of "HD" filters that might contribute a similar image improvement?
