The cracks in glass are better quality, I guess? :-)
i prefer plastic it doesnt shatter, it is lighter and i cant tell the
difference in quality, any problems i have got is down to how good the
original prescription is! you dont get a choice they all plastic
nowadays- no one asked me "would you like glass sir? or a poke in the
eye with a blunt stick!" LOL

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

I prefer glass for the same reason. In my job, plastic and grinding dust
don't go well together. A few days and plastic lenses will start to show
scratches. Glass is far more scratch resistant.

They apply a scratch resistant coating to mine.

As they do to mine. I suppose it does make a difference, but they still
scratch quite easily.
Carborundum grinding dust will even scratch glass lenses unless any dust is
wiped of carefully without using any pressure.
