Actually, Hoya is also a lens maker as well as a glass maker. Check
out:

They manufacture glass plates for LCD displays and for masking, both of
which require a far more advanced technology and precision than it is
required for manufacturing photographic lenses. Who knows? Hoya may
have supplied aspherical elements to Leica. Do I care? Not at all, as
long as these puppies produce fine images.
Leica is not a religion, at least to me.
