I know you all are tired of hearing me preach about Essilor Definity glasses. They are progressive lenses, developed by Johnson & Johnson and sold to Essilor. I was on the R&D team that developed them. They are different from progressive lenses made in the past. Instead of two plastic pieces bonded together, they are cut on CNC lathes and Polished on CNC robotic polishers and coated with the hardest coating in the market and Anti-reflective coated. They have the widest range of any lenses made. They are a little pricy but you can see the front and rear sight and distance better and wider peripheral view than any other lenses. In a couple weeks wearing them, you won't even realize you're wearing progressive lenses. I'm retired from them, and there's nothing in it for me.
