I have no problem getting glass lenses.
I appreciate your point about the danger of glass shattering but I sill
prefer glass because they are less prone to scratching and seem to be better
for my sight (the main reason for preferring them)

Of course plastic lenses are lighter (but not greatly so for my
prescription) and best of all they mist up less when you walk into a warm
room in winter.

I believe that some prescriptions actually require glass lenses, due to
differences in refractive index and the sheer thickness required. This
may have changed.
