If we ignore the location focus you could have two lenses where you moving a lever rotates one compared to the others focal length. Basically how binocular focusing works, or camera Lens focusing. They are just going to be coke bottle bottom lenses Lol
Well, yeah, but we already know how to do bifocals and progressive lenses, which are basically... well, that but stacked on top of each other.
The point is to replace the need to look through a subsection of the lens to see up close for a solution that will give you the ability to switch depending on whether you're focusing close or far. That's a cool idea and fundamentally different to current solutions.
