How Are Prescription Lens Blanks and Glasses Frames Manufactured?

[Wolf105]

Hey everyone, I've been researching for some time now, and I can' find anything about how the actual lens blanks for prescription eyeglass lenses are made, I've looked on websites like this: http://glassescrafter.com/information/how-prescription-glasses-are-made.html but it only explains how the blank is used rather than manufactured... Are they mass produced and if so what machines and machining processes are used? I can't seem to find the information I need for the glasses frames themselves either. I need to know what machines are used for those too. Could anyone provide links please? Thanks in advance!
