Just get my wife and myself new pair of spectacles, which is Nikon as usual 
Only one 'Group', and Three 'Elements' - Multifocal, Transitions and Anti-reflective Coating.
Cost for my wife's over $900, and my one close to $900 for the lens self 
So, all my Canon lenses are REALLY REALLY CHEAP compare to Nikon lens

After all, I'm not getting into the 'war' between Canon Vs Nikon
