Lens blanks and glasses frames

In summary, the conversation discusses the difficulty in finding information about how prescription eyeglass lenses and frames are made. The websites provided only explain how the lenses are used, but not how they are manufactured. The person is specifically looking for information about the machines and processes used in the production of the lenses and frames. Several websites are suggested but the information is still not found.

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!
