Is there a purpose to AR on the back side of a lens?
Is there a purpose to AR on the back (closer to eye) side of the lens? My understanding is this would only be useful if the lens was large enough where light from behind the lens would strike it. Light coming from in front of the lens would be seen no differently whether the lens had antiglare on the rear side correct?
people do this on sunglasses to reduce reflections ................

However it is another gimmick to make more sales for more money.
