当你上了年纪后，眼睛就会渐渐失去对焦的能力——一个跟人类史一样久远的现象——导致我们需要依靠双焦镜、隐形眼镜和激光手术来恢复视力。电子工程师 Nitish Padmanaban 带来了一款令人赏心悦目的先进科技：动态自动对焦镜片。它可以追踪你的视线并适当对焦，不管是近处还是远处。

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.
