I’m not sure what you’re considering the “front” surface, but anti-reflective coating only needs to be applied to the interior surface of eyeglass lenses. The surface facing your eyes. For eyeglasses there’s really no functional purpose to having it applied to the “exterior” surface that faces away from your eyes.

No.

The purpose of having anti-reflective coating on the front surface is to reduce the reflectivity of the spectacles to observers looking at the wearer.

For example, high refractive index materials (which enable thinner lenses) are increasingly 'reflective' - so this becomes a significant and undesirable issue.

So AR coating is partly about vision - and also, partly about 'appearance'.
