The problem they solve
After around 45, the eye's own lens stiffens and near focus fades. Progressive lenses solve this with fixed zones, which means moving your head to find the right part of the lens.
How autofocus lenses work
Sensors estimate how far away you are looking, then the lens changes power electronically. Liquid-crystal designs alter refractive index with a voltage; deformable designs physically change lens shape.
Where the technology stands
Announced and prototyped, not commercially available. Battery life, lens durability, optical quality across the full aperture and price all remain unproven at consumer scale.
