evolution of progressive lens design, lens materials and AR coating

Hallo,

I plan to do a presentation regarding to evolution of progressive lens design, lens materials and AR coating since their inventions to present days. My idea is to create a sales toll that will be very usefull among the sceptical optician in my market. Under "sceptical" I mean the people who belive that everithing is the same, the difference is only the marketing and lens envelopes...
Could you, please, help me with info.

Best regards,
George

I am also one of the "sceptical" ones, while admitting that there is a lot of new stuff around, but as you say also a lot of marketing and envelopes.
