You leave readers with the wrong impression once again. Some glass has bubbles. Some has other physical and chemical imprefections of manufacturing that can create undesirable side effects. And the magic mixes today that produce rare-earth glass, high dispersion glass, and exotic elements like flourite all make today's lenses much different than anything available in the past. Companies spend millions perfecting glass. They patent and guard their creations. All glass is not the same.
