Autofocusing reading glasses of the future

Everyone gradually loses the ability to refocus their eyes, a condition called presbyopia that affects two billion people worldwide. Traditional fixes like reading glasses, bifocals, and even LASIK can’t fully restore the eye’s natural flexibility. Recent advances in focus-tunable lenses, combined with eye tracking and distance sensing, now enable glasses that instantly adjust to what a person looks at. Tests with presbyopic users show these dynamic lenses deliver sharper, faster, and more comfortable vision than any static solution.
