I've been contemplating the future of opticianry, and I don't see a light at the end of the tunnel. I honestly think the field will be phased out in the next generation or two in exchange for automation and salesmen. Unfortunately, with our leaders and the prevalent "sales technique first" attitude, there really is no incentive for change. Also, I'm betting that there will be tv ads that indicate: 3d printers could allow customers to print out their own frames and insert the lens themselves!
